from the Kem Kem beds (Upper Cretaceous, Cenomanian) of Morocco. Here we describe four additional specimens from this informal lithostratigraphic unit: a jaw fragment, two mid-cervical vertebrae, and a humerus. All these specimens show three-dimensional preservation, differing much from the flat condition found in most pterosaur material. The vertebrae are particularly well preserved, and allow accurate observations on the pneumatization of the neural arch. Based on comparable material, we show that at least two edentulous pterosaur species were present in this informal lithostratigraphic unit, thus adding to the growing evidence of considerable pterosaur diversity in northwestern Africa during the "middle" Cretaceous. So far, the Kem Kem beds have the most diverse pterosaur fauna in this continent, with the presence of anhanguerids, azhdarchids, pteranodontids, and tapejarids. Riassunto. Sebbene gli pterosauri rinvenuti in Africa siano ancora rari, negli ultimi anni diversi esemplari sono stati descritti dai cosiddetti Kem Kem beds del Marocco (Cretacico Superiore, Cenomaniano). Nell' articolo descriviamo quattro nuovi reperti provenienti da questa unit脿 litostratigrafica informale: un frammento di mandibola, due vertebre medio-cervicali e un omero. Tutti questi esemplari offrono una conservazione tridimensionale, differendo in questo dalle condizioni di appiattimento proprie di molti reperti di pterosauri. Le vertebre sono particolarmente ben conservate e consentono una accurata osservazione della pneumatizzazione dell'arco neurale. Sulla base di materiale di confronto noi mostriamo che almeno due specie edentule di pterosauri sono presenti in questa unit脿 litostratigrafica informale. Ci貌 incrementa l' evidenza di una considerevole diversit脿 tra gli pterosauri che popolarono l'Africa nordoccidentale durante il "Cretacico medio''. I Kem Kem beds contengono la fauna a pterosauri pi霉 diversificata in questo continente, con la presenza di anhangueridi, azhdarchidi, pteranodontidi e tapejaridi.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="ab0b489204afb49194461e03ad0345ba" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":79853916,"asset_id":69950741,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/79853916/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="69950741"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="69950741"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 69950741;

In the Jiufotang Formation (Lower Cretaceous, Aptian) of northeastern China, pterodactyloids are represented by azhdarchoids and pteranodontoids, including istiodactylids and anhanguerians. Here, we describe a new pterosaur from this unit that represents a new species of toothed pteranodontoid. Its overall morphology is consistent with other toothed pteranodontoids but shows some interesting features such as the orbit being more ventrally positioned than in all other species from this clade. It differs markedly from all other pterosaurs from this unit, including Liaoningopterus, Guidraco and Ikrandraco, with which the new taxon is possibly related. In addition to the description of the new taxon, we also describe the anhanguerid Liaoningopterus gui in more detail. The new species, Liaoningopterus gui, Guidraco venator and Ikrandraco avatar, are large pterosaurs with very distinct tooth morphologies, suggesting that they had different prey preferences, partially explaining how the Jiufotang Formation could bear such a high diversity of pterosaur species.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="5108e10fd9e5309a7aeb38b124759255" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":38133627,"asset_id":13813641,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/38133627/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="13813641"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="13813641"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 13813641;

The first one consists of a complete wing metacarpal 212 mm long, representing an individual with an estimated wing span of 4 m. Small depressions on the anterior surface are present and represent tooth marks showing that this specimen was subjected to scavenging prior to fossilization. The other bone consists of a three-dimensionally preserved cervical vertebra lacking most of the neural arch. The specimens are clearly referable to the derived pterosaur clade Pterodactyloidea. Based on several features such as the position of the pneumatic foramen and the particular shape and proportions of those elements, they possibly are members of, or closely related to, the Anhangueridae. The record of the Australian pterosaurs is reviewed here and represents the known southern distributional limit for Cretaceous pterosaurs, arguing against some older ideas of a more geographically restricted range for these flying reptiles.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="3711003"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="3711003"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 3711003; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=3711003]").text(description); $(".js-view-count[data-work-id=3711003]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 3711003; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='3711003']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=3711003]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":3711003,"title":"New isolated pterodactyloid bones from the Albian Toolebuc Formation (western Queensland, Australia) with comments on the Australian pterosaur fauna","internal_url":"https://www.academia.edu/3711003/New_isolated_pterodactyloid_bones_from_the_Albian_Toolebuc_Formation_western_Queensland_Australia_with_comments_on_the_Australian_pterosaur_fauna","owner_id":3742828,"coauthors_can_edit":true,"owner":{"id":3742828,"first_name":"Benjamin P.","middle_initials":"","last_name":"Kear","page_name":"BenjaminKear","domain_name":"uppsala","created_at":"2013-04-10T04:01:05.125-07:00","display_name":"Benjamin P.

It clearly shows that pterosaurs had two functional oviducts and demonstrates that the reduction of one oviduct was not a prerequisite for developing powered flight, at least in this group. Compositional analysis of one egg suggests the lack of a hard external layer of calcium carbonate. Histological sections of one femur lack medullary bone and further demonstrate that this pterosaur reached reproductive maturity before skeletal maturity. This study shows that pterosaurs laid eggs even smaller than previously thought and had a reproductive strategy more similar to basal reptiles than to birds. Whether pterosaurs were highly precocial or needed parental care is still open to debate.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="ed87cc3c45aa66958bfa9fb872eb036b" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":44765863,"asset_id":18123207,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/44765863/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="18123207"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="18123207"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 18123207;

Trigonosaurus pricei n.gen., n.sp., is based on two specimens, both collected at the Caieira Quarry near Peir贸polis, Minas Gerais. The holotype consists of the five most posterior cervical vertebrae, 10 dorsals, six sacrals and the left ilium (MCT 1488-R). The second specimen (paratype) consists of 10 caudal vertebrae that according to a quarry map, were found isolated but show a similar morphology and compatible size suggesting that they belonged to one individual (MCT 1719-R). Trigonosaurus pricei is diagnosed by a combination of characters such as elongated cervicals and middorsals, dorsal vertebrae 9 and 10 with incipient postzygodiapophyseal lamina and transverse processes well developed throughout the sequence formed by anterior and medial caudals. The occurrence of this new taxon indicates a higher diversity of titanosaurids in the Brazil during the Cretaceous period.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="fb35080e2d27605560513adddad9be27" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":42304569,"asset_id":17149850,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/42304569/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="17149850"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="17149850"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 17149850; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=17149850]").text(description); $(".js-view-count[data-work-id=17149850]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 17149850; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='17149850']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "fb35080e2d27605560513adddad9be27" } } $('.js-work-strip[data-work-id=17149850]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":17149850,"title":"On a titanosaurid (Dinosauria, Sauropoda) vertebral column from the Bauru Group, Late Cretaceous of Brazil.

A new lizard species presented herein is the first acrodontan from South America, indicating acrodontans radiated throughout Gondwana much earlier than previously thought, and that some of the first South American lizards were more closely related to their counterparts in Africa and Asia than to the modern fauna of South America. This suggests both groups of iguanians achieved a worldwide distribution before the final breakup of Pangaea. At some point, non-acrodontans replaced acrodontans and became the only iguanians in the Americas, contrary to what happened on most of the Old World. This discovery also expands the diversity of Cretaceous lizards in South America, which with recent findings, suggests sphenodontians were not the dominant lepidosaurs in that continent as previously hypothesized.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="6042ee0b7104ac4105ab027d3c882f1c" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":42304501,"asset_id":17149849,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/42304501/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="17149849"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="17149849"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 17149849;

Among the least known is the neck of the Tapejaridae that until recently has received little attention. In order to provide further data on the tapejarid cervical anatomy, we describe three specimens from the Romualdo Formation (Lower Cretaceous, Brazil): AMNH 22568 comprises the last five cervical elements of a large individual, AMNH 24445 and MN 4728-V, both including three meso-cervical elements of small individuals. Despite size differences, AMNH 22568 and MN 4728-V are anatomically more similar to each another, showing a pattern of high, laterally flattened (blade-like) neural spines, short centra pierced by two lateral pneumatic foramina. AMNH 24445 presents a distinct anatomy, with low (but still evident) neural spines, more elongated centra with concave ventral surface, and only one lateral pneumatic foramen. Based on comparative studies we refer AMNH 22568 and MN 4728-V to the Thalassodrominae and AMNH 24445 to the Tapejarinae, helping to differentiate the cervical elements of these clades. Thalassodrominae cervical vertebrae can be distinguished by the presence of two lateral pneumatic foramina, a broad centrum (length/width ratio lower than two), and a flat ventral surface. Tapejarinae cervical vertebrae show only one lateral pneumatic foramen, the length/width ratio higher than two, and a concave ventral surface. Thalassodromine and tapejarine cervical vertebrae differ from those of azhdarchids in the presence of lateral pneumatic foramens, developed neural spine, and length/width ratio lower than three, and by being comparatively shorter.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="17149846"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="17149846"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 17149846;

It clearly shows that pterosaurs had two functional oviducts and demonstrates that the reduction of one oviduct was not a prerequisite for developing powered flight, at least in this group. Compositional analysis of one egg suggests the lack of a hard external layer of calcium carbonate. Histological sections of one femur lack medullary bone and further demonstrate that this pterosaur reached reproductive maturity before skeletal maturity. This study shows that pterosaurs laid eggs even smaller than previously thought and had a reproductive strategy more similar to basal reptiles than to birds. Whether pterosaurs were highly precocial or needed parental care is still open to debate.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="17149843"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="17149843"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 17149843;

Here we describe four additional specimens from this informal lithostratigraphic unit: a jaw fragment, two mid-cervical vertebrae, and a humerus. All these specimens show three-dimensional preservation, differing much from the flat condition found in most pterosaur material. The vertebrae are particularly well preserved, and allow accurate observations on the pneumatization of the neural arch. Based on comparable material, we show that at least two edentulous pterosaur species were present in this informal lithostratigraphic unit, thus adding to the growing evidence of considerable pterosaur diversity in northwestern Africa during the "middle" Cretaceous. So far, the Kem Kem beds have the most diverse pterosaur fauna in this continent, with the presence of anhanguerids, azhdarchids, pteranodontids, and tapejarids. Riassunto. Sebbene gli pterosauri rinvenuti in Africa siano ancora rari, negli ultimi anni diversi esemplari sono stati descritti dai cosiddetti Kem Kem beds del Marocco (Cretacico Superiore, Cenomaniano). Nell' articolo descriviamo quattro nuovi reperti provenienti da questa unit脿 litostratigrafica informale: un frammento di mandibola, due vertebre medio-cervicali e un omero. Tutti questi esemplari offrono una conservazione tridimensionale, differendo in questo dalle condizioni di appiattimento proprie di molti reperti di pterosauri. Le vertebre sono particolarmente ben conservate e consentono una accurata osservazione della pneumatizzazione dell'arco neurale. Sulla base di materiale di confronto noi mostriamo che almeno due specie edentule di pterosauri sono presenti in questa unit脿 litostratigrafica informale. Ci貌 incrementa l' evidenza di una considerevole diversit脿 tra gli pterosauri che popolarono l'Africa nordoccidentale durante il "Cretacico medio''. I Kem Kem beds contengono la fauna a pterosauri pi霉 diversificata in questo continente, con la presenza di anhangueridi, azhdarchidi, pteranodontidi e tapejaridi.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="ab0b489204afb49194461e03ad0345ba" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":79853916,"asset_id":69950741,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/79853916/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="69950741"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="69950741"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 69950741;

In the Jiufotang Formation (Lower Cretaceous, Aptian) of northeastern China, pterodactyloids are represented by azhdarchoids and pteranodontoids, including istiodactylids and anhanguerians. Here, we describe a new pterosaur from this unit that represents a new species of toothed pteranodontoid. Its overall morphology is consistent with other toothed pteranodontoids but shows some interesting features such as the orbit being more ventrally positioned than in all other species from this clade. It differs markedly from all other pterosaurs from this unit, including Liaoningopterus, Guidraco and Ikrandraco, with which the new taxon is possibly related. In addition to the description of the new taxon, we also describe the anhanguerid Liaoningopterus gui in more detail. The new species, Liaoningopterus gui, Guidraco venator and Ikrandraco avatar, are large pterosaurs with very distinct tooth morphologies, suggesting that they had different prey preferences, partially explaining how the Jiufotang Formation could bear such a high diversity of pterosaur species.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="5108e10fd9e5309a7aeb38b124759255" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":38133627,"asset_id":13813641,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/38133627/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="13813641"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="13813641"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 13813641;

Based on several features such as the position of the pneumatic foramen and the particular shape and proportions of those elements, they possibly are members of, or closely related to, the Anhangueridae. The record of the Australian pterosaurs is reviewed here and represents the known southern distributional limit for Cretaceous pterosaurs, arguing against some older ideas of a more geographically restricted range for these flying reptiles.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="3711003"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="3711003"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 3711003; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=3711003]").text(description); $(".js-view-count[data-work-id=3711003]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 3711003; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='3711003']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=3711003]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":3711003,"title":"New isolated pterodactyloid bones from the Albian Toolebuc Formation (western Queensland, Australia) with comments on the Australian pterosaur fauna","internal_url":"https://www.academia.edu/3711003/New_isolated_pterodactyloid_bones_from_the_Albian_Toolebuc_Formation_western_Queensland_Australia_with_comments_on_the_Australian_pterosaur_fauna","owner_id":3742828,"coauthors_can_edit":true,"owner":{"id":3742828,"first_name":"Benjamin P.","middle_initials":"","last_name":"Kear","page_name":"BenjaminKear","domain_name":"uppsala","created_at":"2013-04-10T04:01:05.125-07:00","display_name":"Benjamin P.

It clearly shows that pterosaurs had two functional oviducts and demonstrates that the reduction of one oviduct was not a prerequisite for developing powered flight, at least in this group. Compositional analysis of one egg suggests the lack of a hard external layer of calcium carbonate. Histological sections of one femur lack medullary bone and further demonstrate that this pterosaur reached reproductive maturity before skeletal maturity. This study shows that pterosaurs laid eggs even smaller than previously thought and had a reproductive strategy more similar to basal reptiles than to birds. Whether pterosaurs were highly precocial or needed parental care is still open to debate.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="ed87cc3c45aa66958bfa9fb872eb036b" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":44765863,"asset_id":18123207,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/44765863/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="18123207"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="18123207"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 18123207;

Trigonosaurus pricei n.gen., n.sp., is based on two specimens, both collected at the Caieira Quarry near Peir贸polis, Minas Gerais. The holotype consists of the five most posterior cervical vertebrae, 10 dorsals, six sacrals and the left ilium (MCT 1488-R). The second specimen (paratype) consists of 10 caudal vertebrae that according to a quarry map, were found isolated but show a similar morphology and compatible size suggesting that they belonged to one individual (MCT 1719-R). Trigonosaurus pricei is diagnosed by a combination of characters such as elongated cervicals and middorsals, dorsal vertebrae 9 and 10 with incipient postzygodiapophyseal lamina and transverse processes well developed throughout the sequence formed by anterior and medial caudals. The occurrence of this new taxon indicates a higher diversity of titanosaurids in the Brazil during the Cretaceous period.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="fb35080e2d27605560513adddad9be27" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":42304569,"asset_id":17149850,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/42304569/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="17149850"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="17149850"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 17149850; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=17149850]").text(description); $(".js-view-count[data-work-id=17149850]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 17149850; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='17149850']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "fb35080e2d27605560513adddad9be27" } } $('.js-work-strip[data-work-id=17149850]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":17149850,"title":"On a titanosaurid (Dinosauria, Sauropoda) vertebral column from the Bauru Group, Late Cretaceous of Brazil.

A new lizard species presented herein is the first acrodontan from South America, indicating acrodontans radiated throughout Gondwana much earlier than previously thought, and that some of the first South American lizards were more closely related to their counterparts in Africa and Asia than to the modern fauna of South America. This suggests both groups of iguanians achieved a worldwide distribution before the final breakup of Pangaea. At some point, non-acrodontans replaced acrodontans and became the only iguanians in the Americas, contrary to what happened on most of the Old World. This discovery also expands the diversity of Cretaceous lizards in South America, which with recent findings, suggests sphenodontians were not the dominant lepidosaurs in that continent as previously hypothesized.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="6042ee0b7104ac4105ab027d3c882f1c" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":42304501,"asset_id":17149849,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/42304501/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="17149849"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="17149849"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 17149849;

Among the least known is the neck of the Tapejaridae that until recently has received little attention. In order to provide further data on the tapejarid cervical anatomy, we describe three specimens from the Romualdo Formation (Lower Cretaceous, Brazil): AMNH 22568 comprises the last five cervical elements of a large individual, AMNH 24445 and MN 4728-V, both including three meso-cervical elements of small individuals. Despite size differences, AMNH 22568 and MN 4728-V are anatomically more similar to each another, showing a pattern of high, laterally flattened (blade-like) neural spines, short centra pierced by two lateral pneumatic foramina. AMNH 24445 presents a distinct anatomy, with low (but still evident) neural spines, more elongated centra with concave ventral surface, and only one lateral pneumatic foramen. Based on comparative studies we refer AMNH 22568 and MN 4728-V to the Thalassodrominae and AMNH 24445 to the Tapejarinae, helping to differentiate the cervical elements of these clades. Thalassodrominae cervical vertebrae can be distinguished by the presence of two lateral pneumatic foramina, a broad centrum (length/width ratio lower than two), and a flat ventral surface. Tapejarinae cervical vertebrae show only one lateral pneumatic foramen, the length/width ratio higher than two, and a concave ventral surface. Thalassodromine and tapejarine cervical vertebrae differ from those of azhdarchids in the presence of lateral pneumatic foramens, developed neural spine, and length/width ratio lower than three, and by being comparatively shorter.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="17149846"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="17149846"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 17149846;

Three morphotypes were identifi ed, representing the presence of Nothofagus (Nothofagaceae), a type related to Monimiaceae (Magnoliopsida), similar to Monimiophyllum antarcticum, and a possible Magnoliidae (Lauraceaea?).

It clearly shows that pterosaurs had two functional oviducts and demonstrates that the reduction of one oviduct was not a prerequisite for developing powered flight, at least in this group. Compositional analysis of one egg suggests the lack of a hard external layer of calcium carbonate. Histological sections of one femur lack medullary bone and further demonstrate that this pterosaur reached reproductive maturity before skeletal maturity. This study shows that pterosaurs laid eggs even smaller than previously thought and had a reproductive strategy more similar to basal reptiles than to birds. Whether pterosaurs were highly precocial or needed parental care is still open to debate.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="17149843"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="17149843"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 17149843;
