The 3D digital documentation of these sites is in collaboration with the CSIRO and Flinders University.\r\n\r\nAnthony co-supervises two postgraduate students. The research by these students is aimed to deepen our understanding of specific dinosaur track-sites of the Broome Sandstone. This includes (but not limited to) interpreting the types of track-makers, inferences of palaeo-behaviour, and understanding this in the context of the palaeoenvironment.\r\n\r\nAdditionally, Anthony has been involved for several years with UQ's second largest undergraduate course, first year Genetics. With the success of a teaching grant acquisition, he is an active contributor within team of UQ academics, in ways to improve this course, with the results to roll out during the second half of 2015.

The 3D digital documentation of these sites is in collaboration with the CSIRO and Flinders University. <br /> <br />Anthony co-supervises two postgraduate students. The research by these students is aimed to deepen our understanding of specific dinosaur track-sites of the Broome Sandstone. This includes (but not limited to) interpreting the types of track-makers, inferences of palaeo-behaviour, and understanding this in the context of the palaeoenvironment. <br /> <br />Additionally, Anthony has been involved for several years with UQ's second largest undergraduate course, first year Genetics. With the success of a teaching grant acquisition, he is an active contributor within team of UQ academics, in ways to improve this course, with the results to roll out during the second half of 2015.<br /><span class="u-fw700">Supervisors: </span>Dr Steve Salisbury<br /><div class="js-profile-less-about u-linkUnstyled u-tcGrayDarker u-textDecorationUnderline

class="js-work-more-abstract-untruncated hidden">Despite the utilization of new technologies to objectively record and document dinosaur tracks in the field, the categorization and identification of dinosaur tracks remains a largely subjective process. Track Recognition via Artificial Cognition (TRAC) is a project that seeks to provide an objective method for categorizing and identifying dinosaur tracks using track surface photographs. TRAC will employ a combination of different iterations of supervised and unsupervised deep machine learning (ML) approaches to categorize track images drawing from a data set of over 1,000 digital photographs of dinosaur footprint images from around the world. Iterations and adjustments to the ML algorithms will identify natural clusters in the image data set, and our ultimate goal is to build a model capable of assigning an ichnotaxonomic identification to new images that TRAC analyzes. If successful, TRAC can be deployed as an application that can identify dinosaur footprints to ichnotaxon for use by professional paleontologists, citizen scientists, and land managers, with the potential of expanding the scope of the project to include more types of fossils. The TRAC Project is divided into two phases. This paper presents a preliminary report on Phase I, the preparation of the image data set.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="1aa565788f26fa544d4457827a158dea" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":117665830,"asset_id":123167319,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/117665830/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="123167319"><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="123167319"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 123167319;

Represented as a near-complete right hind limb, key aspects of the palaeobiology of Rhoetosaurus remain unresolved. The current study combines three-dimensional modelling and photogrammetry to reconstruct the range of motion (ROM) of the foot of Rhoetosaurus to elicit pedal flexibility and posture. Our findings show that Rhoetosaurus had a high degree of digit mobility at all the metatarsophalangeal joints (total excursion angle &amp;gt;80°) and in the sagittal, transverse and frontal planes at the distal-most interphalangeal joints (excursion angle &amp;gt;100°). The position of the autopodial articular surfaces suggests that the metarsophalangeal joints were permanently elevated in life, an indicator of skeletal digitigrady. This joint may have been ventrally connected with the plantar aspect of the foot by a compliant fibrous pad, consistent with sauropod track data, and therefore likely to have been functional plantigrade, as has been previously suggested. These results provide new insights into the simulated ROM and posture of the hind foot of Rhoetosaurus; we recognize that additional parameters (including loading regimes and ichnological data) provide future modelling aspects to further our understanding of Rhoetosaurus pedal biomechanics.</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="65567150"><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="65567150"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 65567150;

Yet with the exception of tracks assigned to the theropodan ichnotaxon Megalosauropus broomensis in 1967, and more recent work on the preservational characteristics of sauropodan tracks, descriptive accounts of the types of dinosaurian tracks that occur in the Broome Sandstone have been limited, with reports ranging from 6–16 different ichnotaxa. As such, the overall scientific significance of the ichnofauna has remained enigmatic. At the request of Goolarabooloo Traditional Custodians, 300+ hours of ichnological survey work was undertaken on the 25 km stretch of coastline in the vicinity of Walmadany (James Price Point) from 2011–2013. 48 discrete tracksites were identified in this area, containing upward of 20 track types referable to theropods, sauropods, ornithopods and thyreophora...</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="65567146"><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="65567146"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 65567146;

They originate from inland lacustrine clastic exposures of the 581–877 m thick Tugulu Group, variously divided into four formations and subgroups in the northwestern margin of the Junggar Basin. The large Huangyangquan track assemblages occur in the Lower layer/Subgroup II. Similarly-composed track assemblages also occur at the smaller Asphaltite site in the Upper Layer/Subgroup III. The Huangyangquan assemblages have yielded more than 1,500 identified tracks including abundant tracks of avian and non-avian theropods, pterosaurs and turtles and less abundant tracks of stegosaurs.

While historically several Triassic dinosaur tracksites are reported, only one specimen exists for direct study. Evidence for the Rhondda colliery (Ipswich) trackmaker, Upper Triassic Blackstone Formation as a very large-bodied Triassic predatory dinosaur is not supported by the present study because of overestimated footprint length measurements, and we question earlier interpretations that these tracks are Eubrontes-like. Instead, we recognise shared characteristics with the sauropodomorph ichnogenus Evazoum. The track morphology resembles that of Evazoum on account of the distinct shape and position of the impression of the metatarsophalangeal pad for digit IV. The mesaxony of the Blackstone Formation track is also low, but possibly slightly higher than in Evazoum, if the proportions of the digital impressions are correctly interpreted. Finally, the trackway pattern shows constant track inward rotation, a feature observed in typical Evazoum and mostly absent in Eubrontes. Therefore, we assign these Australian tracks as Evazoum ichnosp. indet. If our assessment of the Blackstone Formation tracks is correct, they provide the first and only evidence of basal sauropodomorph dinosaurs from Australia. In addition to this record, we give an overview of other reported (but lost) Australian Triassic dinosaur footprints.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="643f57e38e5c744eb6666eef22034a3c" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":73844038,"asset_id":60365280,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/73844038/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="60365280"><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="60365280"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 60365280;

Thus, many morphotypes have common “generic” labels such as Grallator, Eubrontes, cf. Eubrontes or even “Eubrontes-Megalosauripus” morphotype. These morphotypes are generally more typical of the Jurassic, whereas other more distinctive theropod tracks (Minisauripus and Velociraptorichnus) are restricted to the Cretaceous. The new ichnospecies Eubrontes nobitai ichnosp nov. is distinguished from Jurassic morphotypes based on a very well-preserved trackway and represents the first-named Eubrontes ichnospecies from the Cretaceous of Asia.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="6388d5bd35983cfefee5402282ca339e" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":72499007,"asset_id":57753746,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/72499007/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="57753746"><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="57753746"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 57753746;

Aptian) Jinju formation of South Korea, represent the well-known crocodylomorph ichnogenus Batrachopus. the Korean sample includes multiple, narrow-gauge, pes-only trackways with footprint lengths (FL) 18-24 cm, indicating trackmaker body lengths up to ~3.0 m. Surprisingly, the consistent absence of manus tracks in trackways, with well-preserved digital pad and skin traces, argues for bipedal trackmakers, here assigned to Batrachopus grandis ichnosp. nov. No definitive evidence, either from pes-onmanus overprinting or poor track preservation, suggests the trackways where made by quadrupeds that only appear bipedal. this interpretation helps solve previous confusion over interpretation of enigmatic tracks of bipeds from younger (? Albian) Haman formation sites by showing they are not pterosaurian as previously inferred. Rather, they support the strong consensus that pterosaurs were obligate quadrupeds, not bipeds. Lower Jurassic Batrachopus with foot lengths (FL) in the 2-8 cm range, and cretaceous Crocodylopodus (FL up to ~9.0 cm) known only from Korea and Spain registered narrow gauge trackways indicating semi-terrestrial/terrestrial quadrupedal gaits. Both ichnogenera, from ichnofamily Batrachopodidae, have been attributed to Protosuchus-like semi-terrestrial crocodylomorphs. the occurrence of bipedal B. grandis ichnosp. nov. is evidence of such adaptations in the Korean cretaceous. Crocodylomorph tracks are generally rare in the Mesozoic of Asia. It has been suggested that this is in part due to the lack of sedimentary facies representing suitable habitats for this group of ostensibly aquatic trackmakers 1. However, the crocodylomorph ichnofamily Batrachopodidae 2,3 appears to represent more terrestrially-adapted forms 3,4. As currently defined, the batrachopodids 5 include Batrachopus and Crocodylopodus, the former mostly known from small tracks (~2.0-8.0 cm long) from the Lower Jurassic of North America 4 , Europe 5,6 and Africa 7 , the latter primarily from the Cretaceous of Europe 8,9. The ichnofamily also includes Antipus known only from one well-described Lower Jurassic trackway from North America which is considered a synonym of Batrachopus by some 3 , but not all ichnologists 10. Recently Crocodylopodus was reported from the Lower Cretaceous (?Aptian) 11 Jinju Formation of Korea 12,13 , where it represents the first Asian occurrence, and adds to the extraordinarily rich Jinju Formation, ichnofauna described as a Konservat-Lagerstätten 14-19. Spanish 8,9 and Korean 12,13 Crocodylopodus represent relatively small animals (footprint lengths less than ~9.0-10.0 cm) with slender digit traces, which may reflect penetrative track preservation 20. However, the trackway configuration is diagnostically crocodilian, with elongate tetradactyl pes and outwardly rotated pentadactyl manus, not unlike those of extant crocodilians 21-23 (Supplementary Information: SI Fig. 1). Here we report on a large, newly-discovered Jinju Formation assemblage with multiple trackways of large crocodylomorph tracks with footprint lengths up to 24.0 cm, from the Sacheon Jahye-ri tracksite, near Sacheon City (Fig. 1). These tracks are more than twice as large as any previously reported batrachopodid tracks and closely resemble Batrachopus with well-preserved pes footprints with clear digital pad impressions and localized skin traces.

Aptian) Jinju formation of South Korea, represent the well-known crocodylomorph ichnogenus Batrachopus. the Korean sample includes multiple, narrow-gauge, pes-only trackways with footprint lengths (FL) 18-24 cm, indicating trackmaker body lengths up to ~3.0 m. Surprisingly, the consistent absence of manus tracks in trackways, with well-preserved digital pad and skin traces, argues for bipedal trackmakers, here assigned to Batrachopus grandis ichnosp. nov. No definitive evidence, either from pes-onmanus overprinting or poor track preservation, suggests the trackways where made by quadrupeds that only appear bipedal. this interpretation helps solve previous confusion over interpretation of enigmatic tracks of bipeds from younger (? Albian) Haman formation sites by showing they are not pterosaurian as previously inferred. Rather, they support the strong consensus that pterosaurs were obligate quadrupeds, not bipeds. Lower Jurassic Batrachopus with foot lengths (FL) in the 2-8 cm range, and cretaceous Crocodylopodus (FL up to ~9.0 cm) known only from Korea and Spain registered narrow gauge trackways indicating semi-terrestrial/terrestrial quadrupedal gaits. Both ichnogenera, from ichnofamily Batrachopodidae, have been attributed to Protosuchus-like semi-terrestrial crocodylomorphs. the occurrence of bipedal B. grandis ichnosp. nov. is evidence of such adaptations in the Korean cretaceous. Crocodylomorph tracks are generally rare in the Mesozoic of Asia. It has been suggested that this is in part due to the lack of sedimentary facies representing suitable habitats for this group of ostensibly aquatic trackmakers 1. However, the crocodylomorph ichnofamily Batrachopodidae 2,3 appears to represent more terrestrially-adapted forms 3,4. As currently defined, the batrachopodids 5 include Batrachopus and Crocodylopodus, the former mostly known from small tracks (~2.0-8.0 cm long) from the Lower Jurassic of North America 4 , Europe 5,6 and Africa 7 , the latter primarily from the Cretaceous of Europe 8,9. The ichnofamily also includes Antipus known only from one well-described Lower Jurassic trackway from North America which is considered a synonym of Batrachopus by some 3 , but not all ichnologists 10. Recently Crocodylopodus was reported from the Lower Cretaceous (?Aptian) 11 Jinju Formation of Korea 12,13 , where it represents the first Asian occurrence, and adds to the extraordinarily rich Jinju Formation, ichnofauna described as a Konservat-Lagerstätten 14-19. Spanish 8,9 and Korean 12,13 Crocodylopodus represent relatively small animals (footprint lengths less than ~9.0-10.0 cm) with slender digit traces, which may reflect penetrative track preservation 20. However, the trackway configuration is diagnostically crocodilian, with elongate tetradactyl pes and outwardly rotated pentadactyl manus, not unlike those of extant crocodilians 21-23 (Supplementary Information: SI Fig. 1). Here we report on a large, newly-discovered Jinju Formation assemblage with multiple trackways of large crocodylomorph tracks with footprint lengths up to 24.0 cm, from the Sacheon Jahye-ri tracksite, near Sacheon City (Fig. 1). These tracks are more than twice as large as any previously reported batrachopodid tracks and closely resemble Batrachopus with well-preserved pes footprints with clear digital pad impressions and localized skin traces.

This association prompts the question as to whether invertebrate activity had relations with the buried eggs.

Track Recognition via Artificial Cognition (TRAC) is a project that seeks to provide an objective method for categorizing and identifying dinosaur tracks using track surface photographs. TRAC will employ a combination of different iterations of supervised and unsupervised deep machine learning (ML) approaches to categorize track images drawing from a data set of over 1,000 digital photographs of dinosaur footprint images from around the world. Iterations and adjustments to the ML algorithms will identify natural clusters in the image data set, and our ultimate goal is to build a model capable of assigning an ichnotaxonomic identification to new images that TRAC analyzes. If successful, TRAC can be deployed as an application that can identify dinosaur footprints to ichnotaxon for use by professional paleontologists, citizen scientists, and land managers, with the potential of expanding the scope of the project to include more types of fossils. The TRAC Project is divided into two phases. This paper presents a preliminary report on Phase I, the preparation of the image data set.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="1aa565788f26fa544d4457827a158dea" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":117665830,"asset_id":123167319,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/117665830/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="123167319"><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="123167319"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 123167319;

Represented as a near-complete right hind limb, key aspects of the palaeobiology of Rhoetosaurus remain unresolved. The current study combines three-dimensional modelling and photogrammetry to reconstruct the range of motion (ROM) of the foot of Rhoetosaurus to elicit pedal flexibility and posture. Our findings show that Rhoetosaurus had a high degree of digit mobility at all the metatarsophalangeal joints (total excursion angle &amp;gt;80°) and in the sagittal, transverse and frontal planes at the distal-most interphalangeal joints (excursion angle &amp;gt;100°). The position of the autopodial articular surfaces suggests that the metarsophalangeal joints were permanently elevated in life, an indicator of skeletal digitigrady. This joint may have been ventrally connected with the plantar aspect of the foot by a compliant fibrous pad, consistent with sauropod track data, and therefore likely to have been functional plantigrade, as has been previously suggested. These results provide new insights into the simulated ROM and posture of the hind foot of Rhoetosaurus; we recognize that additional parameters (including loading regimes and ichnological data) provide future modelling aspects to further our understanding of Rhoetosaurus pedal biomechanics.</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="65567150"><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="65567150"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 65567150;

Yet with the exception of tracks assigned to the theropodan ichnotaxon Megalosauropus broomensis in 1967, and more recent work on the preservational characteristics of sauropodan tracks, descriptive accounts of the types of dinosaurian tracks that occur in the Broome Sandstone have been limited, with reports ranging from 6–16 different ichnotaxa. As such, the overall scientific significance of the ichnofauna has remained enigmatic. At the request of Goolarabooloo Traditional Custodians, 300+ hours of ichnological survey work was undertaken on the 25 km stretch of coastline in the vicinity of Walmadany (James Price Point) from 2011–2013. 48 discrete tracksites were identified in this area, containing upward of 20 track types referable to theropods, sauropods, ornithopods and thyreophora...</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="65567146"><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="65567146"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 65567146;

They originate from inland lacustrine clastic exposures of the 581–877 m thick Tugulu Group, variously divided into four formations and subgroups in the northwestern margin of the Junggar Basin. The large Huangyangquan track assemblages occur in the Lower layer/Subgroup II. Similarly-composed track assemblages also occur at the smaller Asphaltite site in the Upper Layer/Subgroup III. The Huangyangquan assemblages have yielded more than 1,500 identified tracks including abundant tracks of avian and non-avian theropods, pterosaurs and turtles and less abundant tracks of stegosaurs.

While historically several Triassic dinosaur tracksites are reported, only one specimen exists for direct study. Evidence for the Rhondda colliery (Ipswich) trackmaker, Upper Triassic Blackstone Formation as a very large-bodied Triassic predatory dinosaur is not supported by the present study because of overestimated footprint length measurements, and we question earlier interpretations that these tracks are Eubrontes-like. Instead, we recognise shared characteristics with the sauropodomorph ichnogenus Evazoum. The track morphology resembles that of Evazoum on account of the distinct shape and position of the impression of the metatarsophalangeal pad for digit IV. The mesaxony of the Blackstone Formation track is also low, but possibly slightly higher than in Evazoum, if the proportions of the digital impressions are correctly interpreted. Finally, the trackway pattern shows constant track inward rotation, a feature observed in typical Evazoum and mostly absent in Eubrontes. Therefore, we assign these Australian tracks as Evazoum ichnosp. indet. If our assessment of the Blackstone Formation tracks is correct, they provide the first and only evidence of basal sauropodomorph dinosaurs from Australia. In addition to this record, we give an overview of other reported (but lost) Australian Triassic dinosaur footprints.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="643f57e38e5c744eb6666eef22034a3c" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":73844038,"asset_id":60365280,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/73844038/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="60365280"><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="60365280"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 60365280;

To date, a moderate diversity of six theropod ichnogenera has been reported, but none of these have been identified at the ichnospecies level. Thus, many morphotypes have common “generic” labels such as Grallator, Eubrontes, cf. Eubrontes or even “Eubrontes-Megalosauripus” morphotype. These morphotypes are generally more typical of the Jurassic, whereas other more distinctive theropod tracks (Minisauripus and Velociraptorichnus) are restricted to the Cretaceous. The new ichnospecies Eubrontes nobitai ichnosp nov. is distinguished from Jurassic morphotypes based on a very well-preserved trackway and represents the first-named Eubrontes ichnospecies from the Cretaceous of Asia.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="6388d5bd35983cfefee5402282ca339e" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":72499007,"asset_id":57753746,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/72499007/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="57753746"><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="57753746"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 57753746;

Aptian) Jinju formation of South Korea, represent the well-known crocodylomorph ichnogenus Batrachopus. the Korean sample includes multiple, narrow-gauge, pes-only trackways with footprint lengths (FL) 18-24 cm, indicating trackmaker body lengths up to ~3.0 m. Surprisingly, the consistent absence of manus tracks in trackways, with well-preserved digital pad and skin traces, argues for bipedal trackmakers, here assigned to Batrachopus grandis ichnosp. nov. No definitive evidence, either from pes-onmanus overprinting or poor track preservation, suggests the trackways where made by quadrupeds that only appear bipedal. this interpretation helps solve previous confusion over interpretation of enigmatic tracks of bipeds from younger (? Albian) Haman formation sites by showing they are not pterosaurian as previously inferred. Rather, they support the strong consensus that pterosaurs were obligate quadrupeds, not bipeds. Lower Jurassic Batrachopus with foot lengths (FL) in the 2-8 cm range, and cretaceous Crocodylopodus (FL up to ~9.0 cm) known only from Korea and Spain registered narrow gauge trackways indicating semi-terrestrial/terrestrial quadrupedal gaits. Both ichnogenera, from ichnofamily Batrachopodidae, have been attributed to Protosuchus-like semi-terrestrial crocodylomorphs. the occurrence of bipedal B. grandis ichnosp. nov. is evidence of such adaptations in the Korean cretaceous. Crocodylomorph tracks are generally rare in the Mesozoic of Asia. It has been suggested that this is in part due to the lack of sedimentary facies representing suitable habitats for this group of ostensibly aquatic trackmakers 1. However, the crocodylomorph ichnofamily Batrachopodidae 2,3 appears to represent more terrestrially-adapted forms 3,4. As currently defined, the batrachopodids 5 include Batrachopus and Crocodylopodus, the former mostly known from small tracks (~2.0-8.0 cm long) from the Lower Jurassic of North America 4 , Europe 5,6 and Africa 7 , the latter primarily from the Cretaceous of Europe 8,9. The ichnofamily also includes Antipus known only from one well-described Lower Jurassic trackway from North America which is considered a synonym of Batrachopus by some 3 , but not all ichnologists 10. Recently Crocodylopodus was reported from the Lower Cretaceous (?Aptian) 11 Jinju Formation of Korea 12,13 , where it represents the first Asian occurrence, and adds to the extraordinarily rich Jinju Formation, ichnofauna described as a Konservat-Lagerstätten 14-19. Spanish 8,9 and Korean 12,13 Crocodylopodus represent relatively small animals (footprint lengths less than ~9.0-10.0 cm) with slender digit traces, which may reflect penetrative track preservation 20. However, the trackway configuration is diagnostically crocodilian, with elongate tetradactyl pes and outwardly rotated pentadactyl manus, not unlike those of extant crocodilians 21-23 (Supplementary Information: SI Fig. 1). Here we report on a large, newly-discovered Jinju Formation assemblage with multiple trackways of large crocodylomorph tracks with footprint lengths up to 24.0 cm, from the Sacheon Jahye-ri tracksite, near Sacheon City (Fig. 1). These tracks are more than twice as large as any previously reported batrachopodid tracks and closely resemble Batrachopus with well-preserved pes footprints with clear digital pad impressions and localized skin traces. Surprisingly the trackways never include manus imprints and therefore appear to indicate exclusively</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="cc704edf5163ac8582391e8a4251199a" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":67745462,"asset_id":49372061,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/67745462/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="49372061"><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="49372061"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 49372061;

However, the trackway configuration is diagnostically crocodilian, with elongate tetradactyl pes and outwardly rotated pentadactyl manus, not unlike those of extant crocodilians 21-23 (Supplementary Information: SI Fig. 1). Here we report on a large, newly-discovered Jinju Formation assemblage with multiple trackways of large crocodylomorph tracks with footprint lengths up to 24.0 cm, from the Sacheon Jahye-ri tracksite, near Sacheon City (Fig. 1). These tracks are more than twice as large as any previously reported batrachopodid tracks and closely resemble Batrachopus with well-preserved pes footprints with clear digital pad impressions and localized skin traces. Surprisingly the trackways never include manus imprints and therefore appear to indicate exclusively</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="731d61c8ea9bc2466404a883c14a36ae" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":67745459,"asset_id":49372060,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/67745459/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="49372060"><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="49372060"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 49372060;

For extinct taxa, pedal posture can be gleaned in part from osteological evidence, augmented by ichnological data. Two different pedal postures have previously been proposed for ornithopodan dinosaurs: a digitigrade posture where the metatarsodigital joint is in close proximity to the plantar surface; and a subunguligrade posture where the metatarsodigital joint is permanently elevated. These postures have been linked to plesiomorphic (non-hadrosaurid) and derived (hadrosaurid) ornithopodan body fossil taxa, respectively. However, ichnological data suggest that the majority of ornithopodan taxa were digitigrade, with tracks typically displaying prominent metatarsodigital pad impressions, including those attributed to hadrosaurids. We propose that the information from both the osteological and the ichnological evidence indicates there are distinct ‘skeletal’ and the ‘functional’ pedal postures within Ornithopoda. The likely plesiomorphic condition for ornithopods is a pedal posture that is both skeletally and functionally digitigrade, while the derived hadrosaurid posture is skeletally subunguligrade but functionally digitigrade. The hadrosaurid-like pedal posture was not limited to hadrosaurids, but may also have been present in some basal hadrosauriforms as well as in some basal Ankylopollexia. The latter possibility indicates that the hadrosauroid-like postural configuration may have evolved independently among different clades. Tracks assigned to the ichnogenus Wintonopus indicate that some small- to medium –bodied ornithopodan trackmakers had permanently elevated metatarsodigital joints but without an associated plantar (metatarsodigital) pad. The suggested pedal posture of these trackmakers is skeletally and functionally subunguligrade, a posture that was previously unrecognized for ornithopodans. By intergrating osteological data with soft-tissue data derived from tracks, we find evidence for multiple transformational pathways within Ornithopoda that mirror the attainment of derived postures in extant lineages.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="8514be1118f0f638b910feee2205546e" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":36945826,"asset_id":11383543,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/36945826/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="11383543"><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="11383543"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 11383543;

Comparative and multivariate data supports the reinterpretation of the large track-maker as an ornithopod, with the tracks assigned to Amblydactylus cf. A. gethingi. Three-dimensional track morphology shows that the small, purportedly theropod prints assigned to Skartopus australis are preservational variants of the ornithopod tracks assigned to Wintonopus latomorum. These re-evaluations remove any evidence for the presence of theropods in the Lark Quarry ichnofauna. The presence of asymmetrical ripples, vegetation drag marks, small dinosaur swimming tracks, and a footprint of a small dinosaur standing in flowing water indicate that the tracks were  preserved in a fluvial environment. Superposition of tracks and other sedimentary structures suggests that the Amblydactylus cf. A. gethingi trackmaker moved across the ancient Lark Quarry site earlier than the Wintonopus trackmakers, such that the two trackmaker species probably did not interact.</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="2373415"><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="2373415"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 2373415; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=2373415]").text(description); $(".js-view-count[data-work-id=2373415]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 2373415; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='2373415']"); 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" } } $('.js-work-strip[data-work-id=2373415]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":2373415,"title":"Re-interpretation of the dinosaur track-maker identities and tracksite scenario at Lark Quarry, of the mid-Cretaceous (late Albian-Cenomanian) Winton Formation, central-western Queensland, Australia.

Tyranosauropus, Skartopus australis and Wintonopus latomorum, respectively. The purported occurrence of theropod prints enabled the original researchers of Lark Quarry to speculate on possible behavioural interactions between dinosaur species: the stalking of prey by a large Allosaurus-sized theropod, and the mixed herding of small theropods with small-to-medium sized ornithopod dinosaurs. <br /> <br />Recent evidence indicates a large ornithopod dinosaur akin to Muttaburrasaurus made the large tracks that were originally assigned to cf. Tyrannosauropus, with these tracks re-interpreted as Amblydactylus cf. A. gethingi. Further analysis of the smaller tracks at Lark Quarry indicates that Skartopus australis tracks can co-occur with those of Wintonopus latomorum, both within individual trackways and within singular footprints. We conclude that Skartopus australis is a junior synonym of the ornithopod ichnotaxa Wintonopus latomorum. The range of variability displayed by Wintonopus tracks can be explained in terms of the dynamic interaction between the track-maker’s foot and underlying substrate. It thus appears that theropods were absent from the Lark Quarry dinosaur tracksite. There is consequently no evidence for the occurrence of large (Allosaurus-sized or larger) theropods in Australia during the mid-Cretaceous.  Nor does Lark Quarry preserve any evidence for the mixed herding of small-bodied theropods with ornithopods. Previous claims for the occurrence of a ‘stampede’ at Lark Quarry need to be reassessed in light of these results.
