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 3D model of the skull of Ramsayia magna (Vomabatidae; Marsupialia) from the Pleistocene of Australia This specimen is reported and described in: Louys, J., Duval,M., Beck, R.M.D., Pease, E., Sobbe, I., Sands, N., Price, G.J. in revision 10/8/2022). Cranial remains of Ramsayia magna from the Late Pleistocene of Australia and the evolution of gigantism in wombats (Vombatidae; Marsupialia). Palaeontology. Abstract Giant wombats (defined here as body mass ≥ 70 kg) are found in the genera Phascolonus, Ramsayia, and perhaps also Sedophascolomys. Of these, Ramsayia is the currently the most poorly known, having been described from fragmentary mandibular and cranial fragments. Here, we report the most complete cranial remains attributable to the genus, identified as the species R. magna. The remains provide new important insights into the anatomy of the species and the evolutionary adaptations to gigantism in Vombatidae. We record parietal sinuses in a vombatid for the first time, an adaptation to increased skull size relative to the braincase. The presence of a prominent premaxillary spine may indicate the species possessed a large, fleshy nose. Both of features are convergent on other large-bodied, non-vombatid extinct megaherbivores of Australia such as Diprotodon optatum. We use the cranial remains to examine the phylogenetic relationships of the giant wombats to other vombatids. Phylogenetic analysis using maximum parsimony and Bayesian inference indicates that Phascolomys, Ramsayia, and Sedophascolomys form a clade, suggesting a single origin of gigantism within Vombatidae. This origin may have been related to the exploitation of poor-quality foods by these taxa, and preceded the extreme specialisations observed in the incisor and cranial anatomy of the giant wombats. U-series and combined U-series and Electron Spin Resonance (ESR) dating methods were applied to one fossil tooth. All sources of uncertainty considered, age calculations systematically correlate the fossil remains to Marine Isotope Stage 5, and an age of approximately 80,000 years can be proposed for this specimen. With only a single well dated occurrence for this taxon, it is currently impossible to determine when and why R. magna became extinct 4 1

Display all details of Functional analysis of the respiratory organs of an obligate air-breathing, aquatic snail (Pomacea canaliculata, Ampullariidae) Ampullariids are freshwater gastropods bearing a gill and a lung, thus showing different degrees of amphibiousness. In particular, Pomacea canaliculata (Caenogastropoda, Ampullariidae) is an obligate air-breather that relies mainly or solely on the lung for dwelling in poorly oxygenated waters, for avoiding predators, while burying in the mud during aestivation, and for oviposition above water level. In this project, we studied the morphological features of the respiratory organs, namely the gill and the lung, and those organs that aid in the different breathing behaviors of this species.
