Media are grouped by projects created by users. Projects tend to contain media tied together by a theme. A project might represent the dataset for a single peer-reviewed paper, the results of a collections digitization project, or data for a digital lesson plan.

Projects can be used to share media ownership and access between project members, and projects can also be used to publish assortments of media and specimens for access and discovery by the public. If you want to share media ownership and access with multiple users across multiple projects, consider creating a user team. Projects can be managed by teams, and users with access to that team also gain access to any projects managed by that team.

Display all details of Triassic stem caecilian supports dissorophoid origin of living amphibians Living amphibians (Lissamphibia) include frogs and salamanders (Batrachia), and the limbless worm-like caecilians (Gymnophiona). The estimated Paleozoic gymnophionan-batrachian molecular divergence suggests a major gap in the record of crown lissamphibians prior to their earliest fossil occurrences in the Triassic Period. Recent studies find a monophyletic Batrachia within dissorophoid temnospondyls, but the absence of pre-Jurassic caecilian fossils has made their relationships to batrachians and affinities to Paleozoic tetrapods controversial. Here we report the geologically-oldest stem caecilian, a crown lissamphibian, from the Late Triassic of Arizona, USA, extending the caecilian record by ~35 Ma. These fossils illuminate the tempo and mode of early caecilian morphological and functional evolution, demonstrating a delayed acquisition of musculoskeletal features associated with fossoriality in living caecilians, including the dual jaw closure mechanism, reduced orbits, and the tentacular organ. The provenance of these fossils suggests a Pangean equatorial origin for caecilians, implying that living caecilian biogeography reflects conserved aspects of caecilian function and physiology in combination with vicariance patterns driven by plate tectonics. These fossils reveal a combination of features unique to caecilians alongside features shared with batrachian and dissorophoid temnospondyls, providing new and compelling evidence supporting a single origin of living amphibians within dissorophoid temnospondyls.

Helochelydra nopcsai 3D models (shell and granicones) This project contains the 3D models for shell remains and granicones of Helochelydra nopcsai, which were uploaded as supplements for the paper "The helochelydrid turtle Helochelydra nopcsai from the Early Cretaceous (late Barremian-early Aptian) fissure fills of Balve, North Rhine-Westphalia, Germany, including a large sample of granicones" by Walter Joyce, Serjoscha Evers, Sara Ren, Yann Rollot, and Achim Schwermann, to be published in Fossil Record. Models and data are currently uploaded to facilitate review, please refrain from citing/using until paper is formerly published. 52 52
Display all details of Braincase and Neuroanatomy of Ceratosuchops inferodios (IWCMS 2014.95.1-3) The digital reconstruction of neurocranial endocasts has elucidated the gross brain structure and potential ecological attributes of many fossil taxa, including Irritator, a spinosaurine spinosaurid from the “mid” Cretaceous (Aptian) of Brazil. With unexceptional hearing capabilities, this taxon was inferred to integrate rapid and controlled pitch-down movements of the head that perhaps aided in the predation of small and agile prey such as fish. However, the neuroanatomy of baryonychine spinosaurids remains to be described, and potentially informs the condition of early spinosaurids. Using micro-computed tomographic scanning (μCT), we reconstruct the braincase endocasts of Baryonyx walkeri and Ceratosuchops inferodios from the Wealden Supergroup (Lower Cretaceous) of England. We show that the gross endocranial morphology is similar to other non-maniraptoriform theropods, and corroborates previous observations of overall endocranial conservatism amongst more basal theropods. Several differences of unknown taxonomic utility are noted between the pair. Baryonychine neurosensory capabilities include low frequency hearing and unexceptional olfaction, whilst the differing morphology of the floccular lobe tentatively suggests less developed gaze stabilisation mechanisms relative to spinosaurines. Given the morphological similarities observed with other basal tetanurans, baryonychines likely possessed similar behavioural sophistication, suggesting that the transition from terrestrial hypercarnivorous ancestors to semi-aquatic “generalists” during the evolution of Spinosauridae did not require substantial modification of the brain and sensory systems.
