The special publication “Ichnology of Latin America - Selected Papers" arose after the Latin American Symposium on Ichnology 2010 (SLIC 2010) that was held from October 30th to November 7th, 2010, in Sao Leopoldo, south of Brazil. About eighty participants attended the conference, representing 21 institutions from South America, 1 from Central America, 3 from North America, 3 from Europe, and 1 from Asia. The ichnologic community of Latin America is not only one of the largest, but also one of the most active. In that sense, it was worthy to produce this special volume as a synthesis of the current knowledge of ichnology in Latin America. <br />Two papers address the importance of the trace fossils in the terminal Proterozoic-early Phanerozoic successions of South America. Netto (p. 14-25) synthesizes the knowledge of biogenic structures, body fossils and microbially induced sedimentary structures of the terminal Proterozoic basins of southern Brazil, and discusses the possible relationship between these beds and those from the Avalonian terrane. Buatois & Mángano (p. 27-36) review the ichnology of the Ediacaran-Cambrian Puncoviscana Formation of the North of Argentina from a paleoecologic and macroevolutionary perspective, emphasizing the importance of the feeding strategies related to microbial matgrounds recorded in this succession, as well as the appearance of new body plans and sophisticated feeding strategies. <br />The other contributions explore part of the Phanerozoic ichnologic record in Latin America. Netto et al. (p. 37-68) make a synthetic review of the ichnology of the Paraná Basin in southern Brazil, with emphasis in the invertebrate record. Alonzo-Muruaga et al. (p. 69-81) present the state-of-art of the ichnology of the Upper Paleozoic deposits of Paganzo and Callingasta-Uspallata basins, in the northwestern Argentina. Carmona et al. (p. 83-97) characterize the most representative trace fossils from the Neogene marine deposits of Patagonia (southeastern Argentina), providing an analysis of this ichnofauna considering local paleoceanographic conditions and exploring its relation with the establishment of the Modern Evolutionary Fauna. VillegasMartín & Rojas-Consuegra (p. 99-106) synthesize the knowledge of the Cuban ichnology through the analysis of the existing literature and the material available in collections. These authors also discuss the future perspectives of this discipline in Cuba. Finally, Souto (p. 107-115) overviews the records of vertebrate’s coprolites found in different units of Latin America, providing a general evaluation of morphologic aspects necessary to describe these structures, and introducing the new methods to study them. <br />Some case studies are also presented herein, reflecting the emergent ichnological research in Latin America. Invertebrate and vertebrate bioturbaton as well as bioerosion are the main addressed themes. Souza et al. (p. 119-128) present an initial approach to the ichnology of the Lower Devonian Maecuru Formation (Amazonas Basin, northern Brazil).  Dentzien-Dias et al. (p. 129-139) describe vertebrate trace fossils from the Upper Jurassic Guará Formation (south of Brazil) and the Batoví Member of the Tacuarembó Formation (north of Uruguay), which contain numerous dinosaur tracks, dominated by theropod and sauropod tracks and different vertebrate burrows. Frank et al. (p. 141-157) synthesize the present knowledge of large tunnels assigned to Cenozoic vertebrates in the southern states of Brazil, and try to identify the possible tracemakers among the South American Megafauna representatives. <br />In the field of bioerosion, Richiano et al. (p. 159-177) focus on the bioerosion structures in Quaternary marine mollusks from the Atlantic Argentine coast (from Rio de la Plata to the south of Santa Cruz province) while Lopes (p. 179-194) describes the bioerosion and bioincrustation in Quaternary body fossils from the Coastal Plain of Rio Grande do Sul State (CPRS), in southern Brazil. <br />There is much more of the ichnology of Latin America than what is presented in this book. Several high quality papers have been published in indexed journals in the last 30 years, and innumerous papers were published in local journals since the 1950s. An important part of this knowledge is missing in this book, but future editions of the Latin American Symposium on Ichnology will help to fill this gap. To all contributors that helped to construct this compendium, our sincere gratitude. Our special thanks to Jordi M. de Gibert, who was a great enthusiast of the ichnologic research developed in Latin America and who contributed to make this book a reality until his passing, last September. <br /> <br /> <br />Renata G.

The special publication “Ichnology of Latin America - Selected Papers\" arose after the Latin American Symposium on Ichnology 2010 (SLIC 2010) that was held from October 30th to November 7th, 2010, in Sao Leopoldo, south of Brazil. About eighty participants attended the conference, representing 21 institutions from South America, 1 from Central America, 3 from North America, 3 from Europe, and 1 from Asia. The ichnologic community of Latin America is not only one of the largest, but also one of the most active. In that sense, it was worthy to produce this special volume as a synthesis of the current knowledge of ichnology in Latin America. \r\nTwo papers address the importance of the trace fossils in the terminal Proterozoic-early Phanerozoic successions of South America. Netto (p. 14-25) synthesizes the knowledge of biogenic structures, body fossils and microbially induced sedimentary structures of the terminal Proterozoic basins of southern Brazil, and discusses the possible relationship between these beds and those from the Avalonian terrane. Buatois \u0026 Mángano (p. 27-36) review the ichnology of the Ediacaran-Cambrian Puncoviscana Formation of the North of Argentina from a paleoecologic and macroevolutionary perspective, emphasizing the importance of the feeding strategies related to microbial matgrounds recorded in this succession, as well as the appearance of new body plans and sophisticated feeding strategies. \r\nThe other contributions explore part of the Phanerozoic ichnologic record in Latin America. Netto et al. (p. 37-68) make a synthetic review of the ichnology of the Paraná Basin in southern Brazil, with emphasis in the invertebrate record. Alonzo-Muruaga et al. (p. 69-81) present the state-of-art of the ichnology of the Upper Paleozoic deposits of Paganzo and Callingasta-Uspallata basins, in the northwestern Argentina. Carmona et al. (p. 83-97) characterize the most representative trace fossils from the Neogene marine deposits of Patagonia (southeastern Argentina), providing an analysis of this ichnofauna considering local paleoceanographic conditions and exploring its relation with the establishment of the Modern Evolutionary Fauna. VillegasMartín \u0026 Rojas-Consuegra (p. 99-106) synthesize the knowledge of the Cuban ichnology through the analysis of the existing literature and the material available in collections. These authors also discuss the future perspectives of this discipline in Cuba. Finally, Souto (p. 107-115) overviews the records of vertebrate’s coprolites found in different units of Latin America, providing a general evaluation of morphologic aspects necessary to describe these structures, and introducing the new methods to study them. \r\nSome case studies are also presented herein, reflecting the emergent ichnological research in Latin America. Invertebrate and vertebrate bioturbaton as well as bioerosion are the main addressed themes. Souza et al. (p. 119-128) present an initial approach to the ichnology of the Lower Devonian Maecuru Formation (Amazonas Basin, northern Brazil). Dentzien-Dias et al. (p. 129-139) describe vertebrate trace fossils from the Upper Jurassic Guará Formation (south of Brazil) and the Batoví Member of the Tacuarembó Formation (north of Uruguay), which contain numerous dinosaur tracks, dominated by theropod and sauropod tracks and different vertebrate burrows. Frank et al. (p. 141-157) synthesize the present knowledge of large tunnels assigned to Cenozoic vertebrates in the southern states of Brazil, and try to identify the possible tracemakers among the South American Megafauna representatives. \r\nIn the field of bioerosion, Richiano et al. (p. 159-177) focus on the bioerosion structures in Quaternary marine mollusks from the Atlantic Argentine coast (from Rio de la Plata to the south of Santa Cruz province) while Lopes (p. 179-194) describes the bioerosion and bioincrustation in Quaternary body fossils from the Coastal Plain of Rio Grande do Sul State (CPRS), in southern Brazil. \r\nThere is much more of the ichnology of Latin America than what is presented in this book. Several high quality papers have been published in indexed journals in the last 30 years, and innumerous papers were published in local journals since the 1950s. An important part of this knowledge is missing in this book, but future editions of the Latin American Symposium on Ichnology will help to fill this gap. To all contributors that helped to construct this compendium, our sincere gratitude. Our special thanks to Jordi M. de Gibert, who was a great enthusiast of the ichnologic research developed in Latin America and who contributed to make this book a reality until his passing, last September.\r\n\r\n\r\nRenata G.

New discoveries based on the examination of 323 specimens include eldoniids, echinoderms, trilobites, monoplacophorans, and non-biomineralizing arthropods that are associated with trace fossils. Based on the observed effects of bioturbation on the preservation of five different animal groups, it is clear that infaunal scavengers/deposit feeders were periodically active on the Kaili sea floor and were able to reach historic layers yielding exceptionally preserved fossils. In general, the average level of infaunal activity is absent to moderate (Ichnofabric Index [i.i.] = 1 to 3) in the Kaili substrate; by contrast, the “Phycodes beds” are completely disturbed by infaunal activity (i.i. = 5). Observed burrow diameter ranges from diminutive (∼ 0.2 mm) to normal (up to 4.2 mm). Computed tomography allows us to visualize the precise geometry of the trace fossil–body fossil association in three dimensions. We concluded that although some Kaili infaunal animals could bore through the biomineralized echinoderms, they did not appear to have scavenged upon these echinoderms based on our three-dimensional reconstruction. Furthermore, Kaili burrowers can reach the historic layers containing exceptionally preserved fossils without altering soft-tissue preservation. On the other hand, we used conventional techniques to reveal that one burrow is filled with fecal pellets (100–200 μm) at its terminal end. Because most burrows are filled with yellow/brown “coarse sediment”, and because there is no compositional difference between the fecal pellets and the surrounding coarse sediment within the burrow, the origin of the yellow/brown “coarse sediment” is interpreted here as parautochthonous and/or autochthonous and as a result of sediment reworking by deposit (or suspension) feeders. The relative scarcity of soft-part preservation in the Kaili Biota compared to the older Chengjiang Biota and the younger Burgess Shale Biota may be the result of post-burial bio-disturbance due to the relatively high intensity of local bioturbation. It is plausible that oxygenation in deeper sediments (facilitated by bioturbation) allowed carcasses in the Kaili biota to undergo a more extensive period of ‘normal’ decay prior to final burial than in other Cambrian Konservat-Lagerstätten.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/350527" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="3d5e7c8e1d32401a9fcae6e4ada20d50" rel="nofollow" data-download="{"attachment_id":2739672,"asset_id":350527,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/2739672/download_file?st=MTczMjc4MDk1Niw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="267468" href="https://nhm.academia.edu/ImranRahman">Imran Rahman</a><script data-card-contents-for-user="267468" type="text/json">{"id":267468,"first_name":"Imran","last_name":"Rahman","domain_name":"nhm","page_name":"ImranRahman","display_name":"Imran Rahman","profile_url":"https://nhm.academia.edu/ImranRahman?f_ri=95531","photo":"https://0.academia-photos.com/267468/55902/97856770/s65_imran.rahman.jpg"}</script></span></span></li><li class="js-paper-rank-work_350527 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="350527"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 350527, container: ".js-paper-rank-work_350527", });

It is plausible that oxygenation in deeper sediments (facilitated by bioturbation) allowed carcasses in the Kaili biota to undergo a more extensive period of ‘normal’ decay prior to final burial than in other Cambrian Konservat-Lagerstätten.","downloadable_attachments":[{"id":2739672,"asset_id":350527,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":267468,"first_name":"Imran","last_name":"Rahman","domain_name":"nhm","page_name":"ImranRahman","display_name":"Imran Rahman","profile_url":"https://nhm.academia.edu/ImranRahman?f_ri=95531","photo":"https://0.academia-photos.com/267468/55902/97856770/s65_imran.rahman.jpg"}],"research_interests":[{"id":162,"name":"Paleobiology","url":"https://www.academia.edu/Documents/in/Paleobiology?f_ri=95531","nofollow":false},{"id":417,"name":"Paleontology","url":"https://www.academia.edu/Documents/in/Paleontology?f_ri=95531","nofollow":false},{"id":1648,"name":"Computed Tomography","url":"https://www.academia.edu/Documents/in/Computed_Tomography?f_ri=95531","nofollow":false},{"id":95531,"name":"Bioturbation","url":"https://www.academia.edu/Documents/in/Bioturbation?f_ri=95531","nofollow":false}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_16259390" data-work_id="16259390" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/16259390/Breaking_the_boundary_The_key_to_bottom_recovery_The_role_of_mysid_crustaceans_in_oxygenizing_bottom_sediments">Breaking the boundary — The key to bottom recovery?

de los sitios arqueológicos de la llanura Interserrana argentina The role of the vizcacha (Lagostomus maximus) in the formation processes of archaeological sites from the Argentinian interhill plains Resumen El movimiento de sedimentos que generan los mamíferos cavadores constituye uno de los principales procesos de formación que sufren los sitios arqueológicos de la región pampeana. En este trabajo se presentan los resultados de un estudio actualista realizado sobre una colonia de vizcachas ubicada en la localidad arqueológica El Trebolar, provincia de Buenos Aires. El objetivo principal fue describir el impacto que estos roedores generan sobre el paisaje, con el fin de identificar su accionar en los sitios arqueológicos de la región. A partir del relevamiento de 21 vizcacheras se pudo establecer que las vizcachas afectan al registro arqueológico de diferentes maneras. Por un lado, su actividad cavadora altera las secuencias estratigráficas y genera asociaciones de materiales de distinta cronología. Por otra parte, las vizcacheras son ocupadas por otros animales, dando lugar a conjuntos faunísticos con alta riqueza taxonómica. Además, estos roedores acarrean a sus madrigueras objetos disponibles localmente. Por último, un alto porcentaje de especímenes óseos presentan surcos que generan las vizcachas para mantener funcionales sus incisivos. En conclusión, las distintas evidencias presentadas permitirían reconocer el accionar de este roedor en el registro fósil, diferenciándolo de otros animales fosoriales que habitan la región pampeana. <br />The movement of sediments generated by digging animals/burrowing mammals is one of the main formation processes affecting the archaeological sites in the Pampas region. In this article, we present/report the results of an actualistic study conducted on a vizcacha colony, in the archaeological locality El Trebolar, province of Buenos Aires. The main objective was to describe the impact that these rodents generate on the landscape in order to identify their action on the archaeological sites of the region. The analysis of 21 vizcacheras showed that the vizcachas affect the archaeological record in different ways. Firstly, their digging activity alters stratigraphic sequences and generates associations of material of different chronology. Secondly, the vizcacheras are occupied by other animals, producing/giving rise to taxonomically rich faunal assemblages. In addition, these rodents carry locally available objects to their burrows.

En este trabajo se presentan los resultados de un estudio actualista realizado sobre una colonia de vizcachas ubicada en la localidad arqueológica El Trebolar, provincia de Buenos Aires. El objetivo principal fue describir el impacto que estos roedores generan sobre el paisaje, con el fin de identificar su accionar en los sitios arqueológicos de la región. A partir del relevamiento de 21 vizcacheras se pudo establecer que las vizcachas afectan al registro arqueológico de diferentes maneras. Por un lado, su actividad cavadora altera las secuencias estratigráficas y genera asociaciones de materiales de distinta cronología. Por otra parte, las vizcacheras son ocupadas por otros animales, dando lugar a conjuntos faunísticos con alta riqueza taxonómica. Además, estos roedores acarrean a sus madrigueras objetos disponibles localmente. Por último, un alto porcentaje de especímenes óseos presentan surcos que generan las vizcachas para mantener funcionales sus incisivos. En conclusión, las distintas evidencias presentadas permitirían reconocer el accionar de este roedor en el registro fósil, diferenciándolo de otros animales fosoriales que habitan la región pampeana. \nThe movement of sediments generated by digging animals/burrowing mammals is one of the main formation processes affecting the archaeological sites in the Pampas region. In this article, we present/report the results of an actualistic study conducted on a vizcacha colony, in the archaeological locality El Trebolar, province of Buenos Aires. The main objective was to describe the impact that these rodents generate on the landscape in order to identify their action on the archaeological sites of the region. The analysis of 21 vizcacheras showed that the vizcachas affect the archaeological record in different ways. Firstly, their digging activity alters stratigraphic sequences and generates associations of material of different chronology. Secondly, the vizcacheras are occupied by other animals, producing/giving rise to taxonomically rich faunal assemblages. In addition, these rodents carry locally available objects to their burrows. Finally, a high percentage of bone specimens present/shows grooves generated by vizcachas to keep their incisors functional. In conclusion, evidence would allow recognizing the action of this rodent in the fossil record, distinguishing it from other fossorial animals that inhabit the Pampas region.","downloadable_attachments":[{"id":66726245,"asset_id":47783622,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":716200,"first_name":"María Clara","last_name":"Alvarez","domain_name":"unsl","page_name":"MaríaClaraAlvarez","display_name":"María Clara Alvarez","profile_url":"https://unsl.academia.edu/Mar%C3%ADaClaraAlvarez?f_ri=95531","photo":"https://0.academia-photos.com/716200/243591/32834623/s65_mar_a_clara.alvarez.jpg"}],"research_interests":[{"id":15780,"name":"Taphonomy","url":"https://www.academia.edu/Documents/in/Taphonomy?f_ri=95531","nofollow":false},{"id":82933,"name":"Tafonomía, sedimentología, paleoambientes","url":"https://www.academia.edu/Documents/in/Tafonomia_sedimentologia_paleoambientes?f_ri=95531","nofollow":false},{"id":87213,"name":"Vertebrate taphonomy","url":"https://www.academia.edu/Documents/in/Vertebrate_taphonomy?f_ri=95531","nofollow":false},{"id":95531,"name":"Bioturbation","url":"https://www.academia.edu/Documents/in/Bioturbation?f_ri=95531","nofollow":false},{"id":111113,"name":"Rodents","url":"https://www.academia.edu/Documents/in/Rodents?f_ri=95531"},{"id":293196,"name":"Actualistic Studies in Taphonomy","url":"https://www.academia.edu/Documents/in/Actualistic_Studies_in_Taphonomy?f_ri=95531"},{"id":315179,"name":"Burrows","url":"https://www.academia.edu/Documents/in/Burrows?f_ri=95531"},{"id":341366,"name":"Tafonomia","url":"https://www.academia.edu/Documents/in/Tafonomia?f_ri=95531"},{"id":504194,"name":"Roedores Subterraneos","url":"https://www.academia.edu/Documents/in/Roedores_Subterraneos?f_ri=95531"},{"id":809582,"name":"Fossorial","url":"https://www.academia.edu/Documents/in/Fossorial?f_ri=95531"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_15364958 coauthored" data-work_id="15364958" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/15364958/Recurrent_constructional_pattern_of_the_crustacean_burrow_Sinusichnus_sinuosus_from_the_Paleogene_and_Neogene_of_Spain">Recurrent constructional pattern of the crustacean burrow Sinusichnus sinuosus from the Paleogene and Neogene of Spain</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">New occurrences of Sinusichnus sinuosus described in the Cenozoic of Spain evidence the almost continuous fossil record of this ichnospecies from the Upper Cretaceous to the Lower Pliocene.

These records are known to imperfectly inscribe the true sequence of events, yet there is large uncertainty regarding the corrections that should be employed to accurately describe the sedimentary history. Here we show in recent records from the Gulf of Aqaba, Red Sea, how events of the abrupt disappearance of the planktonic foraminifer Globigerinoides sacculifer, and episodic depo-sition of the artificial radionuclide 137 Cs, are significantly altered in the sedimentary record compared to their known past timing. Instead of the abrupt disappearance of the foraminifera, we observe a prolonged decline beginning at core depth equivalent to $30 y prior to its actual disappearance and continuing for decades past the event. We further observe asymmet-ric smoothing of the radionuclide peak. Utilization of advection–diffusion–reaction models to reconstruct the original fluxes based on the known absolute timing of the events reveal that it is imperative to use a continuous function to describe biotur-bation. Discretization of bioturbation into mixed and unmixed layers significantly shifts the location of the modeled event. When bioturbation is described as a continuously decreasing function of depth, the peak of a very short term event smears asymmetrically but remains in the right depth. When sudden events repeat while the first spike is still mixed with the upper sediment layer, bioturbation unifies adjacent peaks. The united peak appears at an intermediate depth that does not necessarily correlate with the timing of the individual events. In a third case, a long lasting sedimentary event affected by biotur-bation, the resulting peak is rather weak compared to the actual event and appears deeper in the sediment column than expected based on the termination of the event. The model clearly shows that abrupt changes can only endure in the record if a thick sediment layer settled on the sediment–water interface at once or if bioturbation rates decreased to very low values for a prolonged period of time. In any other case smearing by bioturbation makes an abrupt event appear to have started shortly before the real timing and end long after its true termination.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/29727396" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="6a159d58ff6b03b6acd274c867adc177" rel="nofollow" data-download="{"attachment_id":50182618,"asset_id":29727396,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/50182618/download_file?st=MTczMjc4MDk1Niw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="33341046" href="https://ifm-geomar.academia.edu/ZviSteiner">Zvi Steiner</a><script data-card-contents-for-user="33341046" type="text/json">{"id":33341046,"first_name":"Zvi","last_name":"Steiner","domain_name":"ifm-geomar","page_name":"ZviSteiner","display_name":"Zvi Steiner","profile_url":"https://ifm-geomar.academia.edu/ZviSteiner?f_ri=95531","photo":"/images/s65_no_pic.png"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-29727396">+2</span><div class="hidden js-additional-users-29727396"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/JonathanErez">Jonathan Erez</a></span></div><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/RevitalBookman">Revital Bookman</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-29727396'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-29727396').html();

In any other case smearing by bioturbation makes an abrupt event appear to have started shortly before the real timing and end long after its true termination.","downloadable_attachments":[{"id":50182618,"asset_id":29727396,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":33341046,"first_name":"Zvi","last_name":"Steiner","domain_name":"ifm-geomar","page_name":"ZviSteiner","display_name":"Zvi Steiner","profile_url":"https://ifm-geomar.academia.edu/ZviSteiner?f_ri=95531","photo":"/images/s65_no_pic.png"},{"id":33301795,"first_name":"Jonathan","last_name":"Erez","domain_name":"independent","page_name":"JonathanErez","display_name":"Jonathan Erez","profile_url":"https://independent.academia.edu/JonathanErez?f_ri=95531","photo":"/images/s65_no_pic.png"},{"id":45960904,"first_name":"Revital","last_name":"Bookman","domain_name":"independent","page_name":"RevitalBookman","display_name":"Revital Bookman","profile_url":"https://independent.academia.edu/RevitalBookman?f_ri=95531","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":30505,"name":"Planktonic Foraminifera","url":"https://www.academia.edu/Documents/in/Planktonic_Foraminifera?f_ri=95531","nofollow":false},{"id":61960,"name":"Red Sea","url":"https://www.academia.edu/Documents/in/Red_Sea?f_ri=95531","nofollow":false},{"id":95531,"name":"Bioturbation","url":"https://www.academia.edu/Documents/in/Bioturbation?f_ri=95531","nofollow":false},{"id":446711,"name":"Lead-210 Dating","url":"https://www.academia.edu/Documents/in/Lead-210_Dating?f_ri=95531","nofollow":false},{"id":1260546,"name":"Cesium 137","url":"https://www.academia.edu/Documents/in/Cesium_137?f_ri=95531"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_29725225 coauthored" data-work_id="29725225" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/29725225/Identifying_fossil_rabbit_warrens_Insights_from_a_taphonomical_analysis_of_a_modern_warren">Identifying fossil rabbit warrens: Insights from a taphonomical analysis of a modern warren</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The European rabbit is a small burrowing mammal that is particularly abundant in Western Europe since the Pleistocene and introduced around the world over the last few centuries.

Rabbit bones are regularly recovered from archaeological and palaeontological sites; however, demonstrating their contemporaneity with associated material is often difficult. Additionally, determining the origin of rabbit remains in fossil sites is equally problematic due to the lack of reference collections for natural accumulations. In order to address these issues, we excavated a modern rabbit warren in southwestern France using modern archaeological field methods and techniques. The bone accumulation was analysed using a taphonomic approach in order to determine the most relevant criteria for identifying fossil warrens. The assemblage is heavily fragmented and dominated by individuals less than three months old and, unlike what could be expected, no preserved anatomical connections were documented. Bone concentration is low and connected to occupation duration. Taken together, the criteria we identify aide in better identifying fossil warrens in fossil sites as well as evaluate the integrity of the deposits. Finally, our results also add precision to environmental, biostratigraphic and palaeoethnographic interpretations.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/29725225" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="b466d538f612fdc273cb44b0f257790d" rel="nofollow" data-download="{"attachment_id":50179839,"asset_id":29725225,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/50179839/download_file?st=MTczMjc4MDk1Niw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="3068630" href="https://oulu.academia.edu/MaximePelletier">Maxime Pelletier</a><script data-card-contents-for-user="3068630" type="text/json">{"id":3068630,"first_name":"Maxime","last_name":"Pelletier","domain_name":"oulu","page_name":"MaximePelletier","display_name":"Maxime Pelletier","profile_url":"https://oulu.academia.edu/MaximePelletier?f_ri=95531","photo":"https://0.academia-photos.com/3068630/1008706/24401247/s65_maxime.pelletier.jpg"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-29725225">+3</span><div class="hidden js-additional-users-29725225"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://otmed.academia.edu/JeanphilippeBrugal">Jean-philippe Brugal</a></span></div><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://u-bordeaux1.academia.edu/DavidCochard">David Cochard</a></span></div><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/JeanBaptisteMallye">Jean-Baptiste Mallye</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-29725225'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-29725225').html();

We report field observations of an Upper Cretaceous submarine channel–levee complex within the Rosario Formation, Baja California, Mexico, which provide high-resolution data of lithofacies and ichnofacies distribution, and levee depositional thickness decay along transects perpendicular to the channel axis. Within the levee, both sandstone thickness and the overall proportion of sandstone decrease according to a power law away from the channel axis. Spatial variation in sedimentary structures away from the channel axis is predictable and provides an important link to the depositional flow regime. In channel-proximal locations, structureless sands, parallel lamination, overturned ripples, and ripple cross-lamination (including climbing ripple cross-lamination) are common; in channel-distal localities starved ripples are abundant. Sandstone bed thickness generally increases up stratigraphy within the levee succession, which is interpreted to indicate increasing turbidity current magnitude and/or contemporaneous channel floor aggradation reducing relative levee relief. However, in the most channel-proximal location sandstone bed thickness decreases with height; combined with evidence from both facies and palaeocurrent analysis this allows the position of the levee crest to be inferred. The thickest beds occur at higher levels with increasing distance from the channel axis, using this evidence we present a model for levee growth and migration of the crest.Quantitative analysis of ichnofacies distribution reveals that traces typical of the Cruziana and Skolithos ichnofacies are superimposed over the ‘normal’ background Nereites ichnofacies, forming a ‘bioturbation front’ which is indicative of proximity to the channel. By analogy with modern canyons and channels, the association of Cruziana and Skolithos ichnofacies with the channel may be attributed to oxygen and nutrient enrichment and possible turbidity current transport of organisms responsible for these ichnofacies.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/10472321" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="c2df09665920ea60415ab41fd793f24c" rel="nofollow" data-download="{"attachment_id":47366708,"asset_id":10472321,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/47366708/download_file?st=MTczMjc4MDk1Nyw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="25698937" href="https://rocks.academia.edu/IanKane">Ian Kane</a><script data-card-contents-for-user="25698937" type="text/json">{"id":25698937,"first_name":"Ian","last_name":"Kane","domain_name":"rocks","page_name":"IanKane","display_name":"Ian Kane","profile_url":"https://rocks.academia.edu/IanKane?f_ri=95531","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_10472321 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="10472321"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 10472321, container: ".js-paper-rank-work_10472321", });

By analogy with modern canyons and channels, the association of Cruziana and Skolithos ichnofacies with the channel may be attributed to oxygen and nutrient enrichment and possible turbidity current transport of organisms responsible for these ichnofacies.","downloadable_attachments":[{"id":47366708,"asset_id":10472321,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":25698937,"first_name":"Ian","last_name":"Kane","domain_name":"rocks","page_name":"IanKane","display_name":"Ian Kane","profile_url":"https://rocks.academia.edu/IanKane?f_ri=95531","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":406,"name":"Geology","url":"https://www.academia.edu/Documents/in/Geology?f_ri=95531","nofollow":false},{"id":409,"name":"Geophysics","url":"https://www.academia.edu/Documents/in/Geophysics?f_ri=95531","nofollow":false},{"id":4850,"name":"Migration","url":"https://www.academia.edu/Documents/in/Migration?f_ri=95531","nofollow":false},{"id":10770,"name":"Biostratigraphy","url":"https://www.academia.edu/Documents/in/Biostratigraphy?f_ri=95531","nofollow":false},{"id":37434,"name":"Quantitative analysis","url":"https://www.academia.edu/Documents/in/Quantitative_analysis?f_ri=95531"},{"id":63798,"name":"Cretaceous","url":"https://www.academia.edu/Documents/in/Cretaceous?f_ri=95531"},{"id":65140,"name":"Models","url":"https://www.academia.edu/Documents/in/Models?f_ri=95531"},{"id":70354,"name":"Mesozoic","url":"https://www.academia.edu/Documents/in/Mesozoic?f_ri=95531"},{"id":93027,"name":"Nutrient Enrichment","url":"https://www.academia.edu/Documents/in/Nutrient_Enrichment?f_ri=95531"},{"id":95531,"name":"Bioturbation","url":"https://www.academia.edu/Documents/in/Bioturbation?f_ri=95531"},{"id":95611,"name":"Turbidity Currents","url":"https://www.academia.edu/Documents/in/Turbidity_Currents?f_ri=95531"},{"id":113890,"name":"Power Law","url":"https://www.academia.edu/Documents/in/Power_Law?f_ri=95531"},{"id":125083,"name":"Ichnofossils","url":"https://www.academia.edu/Documents/in/Ichnofossils?f_ri=95531"},{"id":148653,"name":"Upper Cretaceous","url":"https://www.academia.edu/Documents/in/Upper_Cretaceous?f_ri=95531"},{"id":208618,"name":"Phanerozoic","url":"https://www.academia.edu/Documents/in/Phanerozoic?f_ri=95531"},{"id":224515,"name":"ARENA","url":"https://www.academia.edu/Documents/in/ARENA?f_ri=95531"},{"id":239810,"name":"Field Study","url":"https://www.academia.edu/Documents/in/Field_Study?f_ri=95531"},{"id":289260,"name":"Channels","url":"https://www.academia.edu/Documents/in/Channels?f_ri=95531"},{"id":309086,"name":"High Resolution","url":"https://www.academia.edu/Documents/in/High_Resolution?f_ri=95531"},{"id":350162,"name":"SAND","url":"https://www.academia.edu/Documents/in/SAND?f_ri=95531"},{"id":394912,"name":"Flow Regime","url":"https://www.academia.edu/Documents/in/Flow_Regime?f_ri=95531"},{"id":453368,"name":"Spatial Variation","url":"https://www.academia.edu/Documents/in/Spatial_Variation?f_ri=95531"},{"id":484658,"name":"Submarine Canyons","url":"https://www.academia.edu/Documents/in/Submarine_Canyons?f_ri=95531"},{"id":641216,"name":"Quantitative Analysis","url":"https://www.academia.edu/Documents/in/Quantitative_Analysis-1?f_ri=95531"},{"id":849646,"name":"Sedimentary Structures","url":"https://www.academia.edu/Documents/in/Sedimentary_Structures?f_ri=95531"},{"id":976620,"name":"Sedimentary Rocks","url":"https://www.academia.edu/Documents/in/Sedimentary_Rocks?f_ri=95531"},{"id":1144386,"name":"Laminations","url":"https://www.academia.edu/Documents/in/Laminations?f_ri=95531"},{"id":1298252,"name":"Aggradation","url":"https://www.academia.edu/Documents/in/Aggradation?f_ri=95531"},{"id":1843318,"name":"Lamination","url":"https://www.academia.edu/Documents/in/Lamination?f_ri=95531"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_1127931" data-work_id="1127931" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/1127931/Effects_of_hypoxia_on_benthic_macrofauna_and_bioturbation_in_the_Estuary_and_Gulf_of_St_Lawrence_Canada">Effects of hypoxia on benthic macrofauna and bioturbation in the Estuary and Gulf of St. Lawrence, Canada</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The bottom water in the > 300 m deep Lower St. Lawrence Estuary (LSLE) is persistently hypoxic in contrast to the norm oxic bottom waters in the Gulf ofSt. Lawrence (GSL).

We photographed the seabed at 11 stations in the Estuary and Gulf of St. Lawrence (EGSL) during the summers 2006 and 2007 and analysed the images to identify bioturbation traces (lebensspuren) and benthic macrofauna. The objective was to identify the environmental variables that influence the density and diversity of benthic <br />macrofauna and bioturbation traces, and the differences that exist among regions with high, medium and low oxygen levels in the bottom water. The bottom water oxygen concentration is the variable that best explains the densities of total-traces as well as surface-traces. However, the density of these traces was higher in hypoxic regions than in well-oxygenated regions. The higher density of traces in the hypoxic region of the LSLE is mainly due to the activities of the surface deposit feeder Ophiura sp., which occurs in large numbers in this region. Possible explanations explored are stress behaviour of the organisms in response to hypoxia and different benthic macrofauna community structures between the <br />hypoxic regions of the LSLE and the normoxic regions of the GSL. In the former, surface deposit feeders and low-oxygen tolerant species dominate over suspension feeclers and low-oxygen intolerant species.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/1127931" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="b6bcb7ab6ecabd23a7f302c105e35e1c" rel="nofollow" data-download="{"attachment_id":6964265,"asset_id":1127931,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/6964265/download_file?st=MTczMjc4MDk1Nyw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="994468" href="https://nature.academia.edu/JeanMarcGagnon">Jean-Marc Gagnon</a><script data-card-contents-for-user="994468" type="text/json">{"id":994468,"first_name":"Jean-Marc","last_name":"Gagnon","domain_name":"nature","page_name":"JeanMarcGagnon","display_name":"Jean-Marc Gagnon","profile_url":"https://nature.academia.edu/JeanMarcGagnon?f_ri=95531","photo":"https://0.academia-photos.com/994468/68959336/57350210/s65_jean-marc.gagnon.jpg"}</script></span></span></li><li class="js-paper-rank-work_1127931 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="1127931"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 1127931, container: ".js-paper-rank-work_1127931", });

Ichnofabric analysis of the member indicates that relatively small examples of Skolithos terminating at the same foreset boundary were formed during a brief colonization window after a single depositional event, that particularly long Skolithos specimens are equilibrichnia, and that palimpsests of Skolithos represent the marginal, slightly deeper water fringes of the Pipe Rock Member depositional environment. Nearest neighbour analysis, however, suggests that such palimpsests were uncommon. A much more diverse trace fossil assemblage is present in the overlying Fucoid Member (An t-Sròn Formation), comprising Cruziana barbata, Dactylophycus, Didymaulichnus, Halopoa imbricata, ?Margaritichnus, Monocraterion, Monomorphichnus, Palaeophycus striatus, P. tubularis, ?Phycodes, Planolites montanus, ?Polarichnus, Rusophycus ramellensis, ?Psammichnites, Skolithos and various unidentified traces, and represents the Cruziana ichnofacies. Above the Fucoid Member, the Salterella Grit Member ichnofauna is more impoverished, yielding only Cruziana, Monocraterion, Rusophycus, Skolithos and ?Spirophyton. The ichnological variations between the Pipe Rock, Fucoid and Salterella Grit members are interpreted as being driven by changes in sea level. The low trace fossil diversity in the Pipe Rock Member indicates opportunistic colonization of laterally extensive, shoreface sediments deposited by regular influxes of terrigenous material, which were overlain by more distal, ichnologically diverse sediments (Fucoid Member) as sea level rose. A minor regression then caused an increase in terrigenous sediment input, producing an impoverished, proximal Cruziana ichnofacies (Salterella Grit Member).</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/9213703" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="0c8153b4068d3c3fb7f336ed6aed5fda" rel="nofollow" data-download="{"attachment_id":47849642,"asset_id":9213703,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/47849642/download_file?st=MTczMjc4MDk1Nyw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="21116207" href="https://bgs.academia.edu/RobertRaine">Robert Raine</a><script data-card-contents-for-user="21116207" type="text/json">{"id":21116207,"first_name":"Robert","last_name":"Raine","domain_name":"bgs","page_name":"RobertRaine","display_name":"Robert Raine","profile_url":"https://bgs.academia.edu/RobertRaine?f_ri=95531","photo":"https://0.academia-photos.com/21116207/5826828/6620446/s65_robert.raine.jpg_oh_a130da7e52741090561fe6f777cbfe22_oe_54da498d___gda___1423061165_1ce5519ea36a718c49226d09c25660ff"}</script></span></span></li><li class="js-paper-rank-work_9213703 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="9213703"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 9213703, container: ".js-paper-rank-work_9213703", });

Ichnofabric analysis of the member indicates that relatively small examples of Skolithos terminating at the same foreset boundary were formed during a brief colonization window after a single depositional event, that particularly long Skolithos specimens are equilibrichnia, and that palimpsests of Skolithos represent the marginal, slightly deeper water fringes of the Pipe Rock Member depositional environment. Nearest neighbour analysis, however, suggests that such palimpsests were uncommon. A much more diverse trace fossil assemblage is present in the overlying Fucoid Member (An t-Sròn Formation), comprising Cruziana barbata, Dactylophycus, Didymaulichnus, Halopoa imbricata, ?Margaritichnus, Monocraterion, Monomorphichnus, Palaeophycus striatus, P. tubularis, ?Phycodes, Planolites montanus, ?Polarichnus, Rusophycus ramellensis, ?Psammichnites, Skolithos and various unidentified traces, and represents the Cruziana ichnofacies. Above the Fucoid Member, the Salterella Grit Member ichnofauna is more impoverished, yielding only Cruziana, Monocraterion, Rusophycus, Skolithos and ?Spirophyton. The ichnological variations between the Pipe Rock, Fucoid and Salterella Grit members are interpreted as being driven by changes in sea level. The low trace fossil diversity in the Pipe Rock Member indicates opportunistic colonization of laterally extensive, shoreface sediments deposited by regular influxes of terrigenous material, which were overlain by more distal, ichnologically diverse sediments (Fucoid Member) as sea level rose. A minor regression then caused an increase in terrigenous sediment input, producing an impoverished, proximal Cruziana ichnofacies (Salterella Grit Member).","downloadable_attachments":[{"id":47849642,"asset_id":9213703,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":21116207,"first_name":"Robert","last_name":"Raine","domain_name":"bgs","page_name":"RobertRaine","display_name":"Robert

An outdoor experiment was set to monitor physicochemical and microbiolog-ical parameters of water and sediment influencing P diagenesis. A pilot study with radioactive 32 P was also performed under the agency of raking and bacteria (Bacillus sp.). Raking was more effective in release of P under unfertilized conditions by significantly enhancing orthophosphate (35%) and soluble reactive phosphate (31.8%) over respective controls. Biotur-bation increased total and available P in sediments significantly as compared to control. The rates of increase were higher in the unfertilized conditions (17.6–28.4% for total P and 12.2 to 23.2% for available P) than the fertilized ones (6.5–12.4% for total P and 9.1 to 15% for available P). The combined effects of raking and bioturbation on orthophosphate and soluble reactive phosphate were also stronger under unfertilized state (54.5 and 81.8%) than fertilized ones (50 and 70%).

An outdoor experiment was set to monitor physicochemical and microbiolog-ical parameters of water and sediment influencing P diagenesis. A pilot study with radioactive 32 P was also performed under the agency of raking and bacteria (Bacillus sp.). Raking was more effective in release of P under unfertilized conditions by significantly enhancing orthophosphate (35%) and soluble reactive phosphate (31.8%) over respective controls. Biotur-bation increased total and available P in sediments significantly as compared to control. The rates of increase were higher in the unfertilized conditions (17.6–28.4% for total P and 12.2 to 23.2% for available P) than the fertilized ones (6.5–12.4% for total P and 9.1 to 15% for available P). The combined effects of raking and bioturbation on orthophosphate and soluble reactive phosphate were also stronger under unfertilized state (54.5 and 81.8%) than fertilized ones (50 and 70%).

The total processed sediment produced by burrowing and foraging activities in a population from a peri-urban mangrove area receiving untreated domestic sewage was compared with that from a forest not affected by urban wastewater.

Immediately after deposition, surviving deep-burrowing animals re-opened their connection to the sea floor to obtain water <br />for respiration and/or food take-up. Later, small-sized meiofauna and then <br />macrofauna re-colonized the sea floor, mixing newly deposited organic fluff <br />with the underlying ash. Consequently, ash deposits thinner than 1 mm have <br />not often been observed as a continuous layer when cored six years after the <br />eruption, while ash about 2 mm thick is now patchily bioturbated. In areas <br />covered by ash thicker than 5 mm, mixing by benthic animals is controlled <br />mainly by the adaptation of the burrowing fauna to variations in grain-size, the <br />rate of background sedimentation, the availability of benthic food on and <br />within the sediment and pore water oxygen levels. With respect to these <br />factors, four provinces can be distinguished: (i) Along the Philippines margin <br />run-off from land fuels primary production that, in turn, leads to a high <br />benthic food content. The benthic fauna is adapted to a variable grain-size and <br />rapid sedimentation. Therefore, mixing is intense and the preservation <br />potential of the ash layer is low. (ii) In areas affected by deposition of <br />hyperpycnites and turbidites, i.e. in canyons in front of river mouths and in <br />the Manila Trench, the ash layer is preserved due to rapid burial. (iii) The area <br />to the west to about 116 E receives low amounts of benthic food, benthic <br />mixing is less intense and the preservation potential of the ash is high. (iv) The <br />central South China Sea, where the ash is thinner than 3 cm, is affected by <br />intense wind mixing and upwelling and the benthic food content is high; thus, <br />the chance that the ash will be preserved as a sharp-based layer is low. <br />Consequently, the style of ash preservation has palaeo-environmental <br />significance.

Immediately after deposition, surviving deep-burrowing animals re-opened their connection to the sea floor to obtain water\r\nfor respiration and/or food take-up. Later, small-sized meiofauna and then\r\nmacrofauna re-colonized the sea floor, mixing newly deposited organic fluff\r\nwith the underlying ash. Consequently, ash deposits thinner than 1 mm have\r\nnot often been observed as a continuous layer when cored six years after the\r\neruption, while ash about 2 mm thick is now patchily bioturbated. In areas\r\ncovered by ash thicker than 5 mm, mixing by benthic animals is controlled\r\nmainly by the adaptation of the burrowing fauna to variations in grain-size, the\r\nrate of background sedimentation, the availability of benthic food on and\r\nwithin the sediment and pore water oxygen levels. With respect to these\r\nfactors, four provinces can be distinguished: (i) Along the Philippines margin\r\nrun-off from land fuels primary production that, in turn, leads to a high\r\nbenthic food content. The benthic fauna is adapted to a variable grain-size and\r\nrapid sedimentation. Therefore, mixing is intense and the preservation\r\npotential of the ash layer is low. (ii) In areas affected by deposition of\r\nhyperpycnites and turbidites, i.e. in canyons in front of river mouths and in\r\nthe Manila Trench, the ash layer is preserved due to rapid burial. (iii) The area\r\nto the west to about 116\u0002 E receives low amounts of benthic food, benthic\r\nmixing is less intense and the preservation potential of the ash is high. (iv) The\r\ncentral South China Sea, where the ash is thinner than 3 cm, is affected by\r\nintense wind mixing and upwelling and the benthic food content is high; thus,\r\nthe chance that the ash will be preserved as a sharp-based layer is low.\r\nConsequently, the style of ash preservation has palaeo-environmental\r\nsignificance. Older buried and burrowed event layers provide further\r\ninformation to elucidate the fate of the 1991 Pinatubo ash layer; in general\r\ntheir appearance fits with observations in the Recent.\r\n\r\n","downloadable_attachments":[{"id":82920505,"asset_id":74812045,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":2173263,"first_name":"Andreas","last_name":"Wetzel","domain_name":"unibas","page_name":"AndreasWetzel","display_name":"Andreas Wetzel","profile_url":"https://unibas.academia.edu/AndreasWetzel?f_ri=95531","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":406,"name":"Geology","url":"https://www.academia.edu/Documents/in/Geology?f_ri=95531","nofollow":false},{"id":420,"name":"Sedimentology","url":"https://www.academia.edu/Documents/in/Sedimentology?f_ri=95531","nofollow":false},{"id":2588,"name":"Ichnology","url":"https://www.academia.edu/Documents/in/Ichnology?f_ri=95531","nofollow":false},{"id":75725,"name":"Deep sea ecology","url":"https://www.academia.edu/Documents/in/Deep_sea_ecology?f_ri=95531","nofollow":false},{"id":82703,"name":"South China Sea","url":"https://www.academia.edu/Documents/in/South_China_Sea?f_ri=95531"},{"id":95531,"name":"Bioturbation","url":"https://www.academia.edu/Documents/in/Bioturbation?f_ri=95531"},{"id":206238,"name":"Volcanic ash","url":"https://www.academia.edu/Documents/in/Volcanic_ash?f_ri=95531"},{"id":796144,"name":"Deep Sea","url":"https://www.academia.edu/Documents/in/Deep_Sea?f_ri=95531"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_41466853" data-work_id="41466853" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/41466853/Teasing_Spatial_Structure_from_Malham_Tarn_Site_A_preliminary_analysis_of_a_bioturbated_Mesolithic_site_in_North_Yorkshire_England">Teasing Spatial Structure from Malham Tarn Site A: preliminary analysis of a bioturbated Mesolithic site in North Yorkshire, England</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Malham Tarn Site A is an Early through Late Mesolithic site at moderate altitudes in the Pennines of West Yorkshire, north-central England.

The influence of the macrofauna on nutrients released from the sediments was investigated experimentally in the laboratory using sediment cores from the Swan–Canning Estuary. Excretion rates of common benthic species were also measured to quantify the role of the macrofauna in estuarine nutrient cycling.The presence of macrofauna increased the release of phosphate and ammonium into the water column but decreased the release, or resulted in uptake, of nitrate by the sediments. There were no significant differences in porewater concentrations of ammonium, nitrate or phosphate between treatments with and without macrofauna. The macrofauna clearly had an important role in nutrient fluxes, as nutrient release differed between cores with and without fauna, and nutrient fluxes were significantly correlated with increased faunal biomass.Other factors, such as season and dissolved oxygen concentrations, influenced the concentration of nutrients released. Ammonium was released into the overlying water column at higher rates in winter than summer, while nitrate was released at higher rates in summer than winter. Aeration did not have a significant effect on nutrient fluxes, however there was a significant increase in filterable reactive phosphorus, and decrease in nitrate, in the porewater of cores which were not aerated.Benthic species excreted phosphate, nitrate and ammonium, with ammonium present in the largest amounts. Comparison of excretion rates to the amount of nutrients released into the water column in the core experiments revealed that excretion could account for 30% of the phosphate and >200% of the ammonium measured in the water column.Clearly the benthic macrofauna have a significant role with respect to benthic nutrient fluxes within the Swan–Canning Estuary, with benthic regeneration of nutrients estimated to equal external loading of nutrients. However, further work is required to more precisely define the influence of seasonality, dissolved oxygen, microbial activity and sediment characteristics on nutrient fluxes.

The influence of the macrofauna on nutrients released from the sediments was investigated experimentally in the laboratory using sediment cores from the Swan–Canning Estuary. Excretion rates of common benthic species were also measured to quantify the role of the macrofauna in estuarine nutrient cycling.The presence of macrofauna increased the release of phosphate and ammonium into the water column but decreased the release, or resulted in uptake, of nitrate by the sediments. There were no significant differences in porewater concentrations of ammonium, nitrate or phosphate between treatments with and without macrofauna. The macrofauna clearly had an important role in nutrient fluxes, as nutrient release differed between cores with and without fauna, and nutrient fluxes were significantly correlated with increased faunal biomass.Other factors, such as season and dissolved oxygen concentrations, influenced the concentration of nutrients released. Ammonium was released into the overlying water column at higher rates in winter than summer, while nitrate was released at higher rates in summer than winter. Aeration did not have a significant effect on nutrient fluxes, however there was a significant increase in filterable reactive phosphorus, and decrease in nitrate, in the porewater of cores which were not aerated.Benthic species excreted phosphate, nitrate and ammonium, with ammonium present in the largest amounts. Comparison of excretion rates to the amount of nutrients released into the water column in the core experiments revealed that excretion could account for 30% of the phosphate and \u003e200% of the ammonium measured in the water column.Clearly the benthic macrofauna have a significant role with respect to benthic nutrient fluxes within the Swan–Canning Estuary, with benthic regeneration of nutrients estimated to equal external loading of nutrients. However, further work is required to more precisely define the influence of seasonality, dissolved oxygen, microbial activity and sediment characteristics on nutrient fluxes.

This is the only European fiddler crab species, which is found in the SW of the Iberian Peninsula. The study has been carried out in the estuary of the Piedras river in Lepe (southern Huelva). The obtained casts allow to study burrow morphologies, which are similar to those described as Psilonichnus in the fossil record. This ichnogenus is present in Neogene marine sedimentary rocks from the Lepe area. The use of this technique is a useful tool not only to learn about the burrowing behavior of modern animals but also to support tracemaker interpretations of fossil burrows.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/395447" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="4669e429ce749a7c93d0e3e755e42412" rel="nofollow" data-download="{"attachment_id":1892999,"asset_id":395447,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/1892999/download_file?st=MTczMjc4MDk1Nyw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="147923" href="https://ub.academia.edu/JordiMdeGibert">Jordi M.

This is the only European fiddler crab species, which is found in the SW of the Iberian Peninsula. The study has been carried out in the estuary of the Piedras river in Lepe (southern Huelva). The obtained casts allow to study burrow morphologies, which are similar to those described as Psilonichnus in the fossil record. This ichnogenus is present in Neogene marine sedimentary rocks from the Lepe area. The use of this technique is a useful tool not only to learn about the burrowing behavior of modern animals but also to support tracemaker interpretations of fossil burrows.","downloadable_attachments":[{"id":1892999,"asset_id":395447,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":147923,"first_name":"Jordi M.","last_name":"(de) Gibert","domain_name":"ub","page_name":"JordiMdeGibert","display_name":"Jordi M.
