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 Expanded Sampling Across Ontogeny in Deltasuchus motherali (Neosuchia, Crocodyliformes)
|New material attributable to Deltasuchus motherali, a neosuchian from the Cenomanian of Texas, provides sampling across much of the ontogeny of this species. Detailed descriptions provide both information about the paleobiology of this species, particularly with regards to how growth and development affected diet. Overall snout shape became progressively wider and more robust with age, suggesting that dietary shifts from juvenile to adult were not only a matter of size change, but functional performance as well. These newly described elements provide additional characters upon which to base more robust phylogenetic analyses. The authors provide a revised diagnosis of this species, describing the new material and discussing incidents of apparent ontogenetic variation across the sampled population. The results of the ensuing phylogenetic analyses both situate Deltasuchus within an endemic clade of Appalachian crocodyliforms, separate and diagnosable from goniopholidids and pholidosaurs, herein referred to as Paluxysuchidae.

|Display all details of The neurocranium of Ekweeconfractus amorui gen. et sp. nov. (Hyaenodonta, Mammalia) and the evolution of the brain in some hyaenodontan carnivores
|We report on a nearly complete cranium of Ekweeconfractus amorui gen. et sp. nov. (Hyaenodonta, Teratodontinae), from the early Miocene of Moruorot, Kenya. The cranium is dorsoventrally compressed, but sufficiently intact to allow for digital reconstruction of the neurocranium, resulting in a digital endocast that gives us a first glimpse into teratodontine brain morphology. The virtual endocast is one of the most well preserved of any hyaenodont known to date, with many of the cranial nerves and blood vessels identifiable. Endocasts are known from only a handful of hyaenodont species and little work has been done on hyaenodont brains in recent decades. To better understand the evolution of the brain in these animals, we place the endocast of E. amorui gen. et sp. nov., as well as several other previously described endocasts, in the latest phylogenetic framework. This analysis suggests that the expansion of the neocortex occurred convergently in several clades of Hyaenodonta. Our study provides a basis for future research on brain evolution in Hyaenodonta.
|Display all details of Anatomical diversification of a novel skeletal element in bat feet
|This project includes CT scans on bat feet generated for the following manuscript: Stanchak, K. E., Arbour, J. H. and Santana, S. E. (2019), Anatomical diversification of a skeletal novelty in bat feet. Evolution, 73: 1591-1603. doi:10.1111/evo.13786 In this study, we found much anatomical variation in the calcar, an additional skeletal element in bat feet that articulates with the calcaneus. These scans demonstrate the extent of skeletal diversity in the bat ankle region.

|Display all details of Sterkfontein
|The caves and quarries at Sterkfontein, 50 km northwest of Johannesburg, are the richest <i>Australopithecus</i> -bearing site in Africa. Over 800 specimens have been recovered there since the 1936 discovery of the first adult <i>Australopithecus</i> . In particular, Member 4 contains abundant <i>Australopithecus</i> remains (including "Mrs Ples"), while Member 5 has yielded large Oldowan and Early Acheulean stone tool assemblages and hominin remains attributed to the genera <i>Homo</i> and <i>Paranthropus</i> . The Sterkfontein site is well-known for having yielded the iconic skull and associated skeleton of the “Little Foot” in Member 2. More recently, additional hominin remains were reported from the nearby Jacovec Cave and Milner Hall. In addition to the hominin remains, abundant associated faunal assemblages have been excavated and include a large and diverse non-hominin primate collection. This project aims at providing 3D surfaces of newly hominin and primate remains as well as of the stone tools excavated at Sterkfontein.
