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 Phenotypic integration in feliform carnivores The skeleton is a complex arrangement of anatomical structures that covary to various degrees depending on both intrinsic and extrinsic factors. Among the Feliformia, many species are characterized by predator lifestyles providing a unique opportunity to investigate the impact of highly specialised hypercarnivorous diet on phenotypic integration and shape diversity. To do so, we compared the shape of the skull, mandible, humerus, and femur of species in relation to their feeding strategies (hypercarnivorous versus generalist species) and prey preference (predators of small versus large prey) using three‐dimensional geometric morphometric techniques. Our results highlight different degrees of morphological integration in the Feliformia depending on the functional implication of the anatomical structure, with an overall higher covariation of structures in hypercarnivorous species. The skull and the forelimb are not integrated in generalist species whereas they are in hypercarnivores. These results can potentially be explained by the different feeding strategies of these species. Contrary to our expectations, hypercarnivores display a higher disparity for the skull than generalist species. This is probably due to the fact that a specialisation toward high‐meat diet could be achieved through various phenotypes. Finally, humeri and femora display shape variations depending on relative prey size preference. Large species feeding on large prey tend to have robust long bones due to higher biomechanical constraints. 12 3
Display all details of The influence of estrogen deficiency on the structural and mechanical properties of the rat cortical bone This work describes the changes in the cortical bone of the rat following ovariectomy. We have previously described the unique structure of rat cortical bone, which contains two components: a region with highly organized circumferential-lamellar material and a centrally located region with disordered material. Thisdy evaluates the influence of ovariectomy on these regions separately, using synchrotron based microtomography. Structural features of femoral cortical bone were studied by scanning electron microscopy and synchrotron-based micro-CT. Small cylindrical samples were prepared from the distal shaft of 8 left femora of each group for multi-resolution imaging by monochromatic synchrotron radiation radiography available on BAMline beamline of the BESSY II storage ring of the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB). the entire circumferences of the cortex was scanned at a resolution of 4.35 μm effective pixel size, and the protuberance was scanned at an effective pixel size of 1.75 μm. 15 15

Display all details of Baculites compressus Hydrodynamics External model of Baculites compressus used in hydrodynamic simulations. Peterman, David 1 1
Display all details of ABAC/oVert Whole Rodent skeleton microCT These rodent specimens were scanned at Friday Harbor labs, WA in May 2019 from funding by the Overt TCN. Specimens are from the University of Florida's Natural History Museum and the University of Washington's Burke Museum. The scans were performed by a team led by Andrew McIntosh from Abraham Baldwin Agricultural College, Georgia. Multiple specimens were scanned together and then segmented out individually using Slicer3d/slicermorph. If you notice there is missing anatomy on the scan please contact me at afmcintosh@msn.com and I can provide the raw scanning file. 84 84

Display all details of Re-evaluation of the cranial osteology and phylogenetic position of the early crocodyliform Eopneumatosuchus colberti, with an emphasis on its endocranial anatomy Eopneumatosuchus colberti Crompton and Smith 1980, known from a single partial skull, is an enigmatic crocodylomorph from the Lower Jurassic Kayenta Formation. In spite of its unique morphology, an exceptionally pneumatic braincase, and presence during a critical time period of crocodylomorph evolution, relatively little is known about this taxon. Here, we re-describe the external cranial morphology of E. colberti, present novel information on endocranial anatomy, evaluate its phylogenetic position among early crocodylomorphs, and seek to better characterize its ecology. Our examination clarifies key aspects of cranial suture paths and braincase anatomy. Comparisons with related taxa (e.g., Protosuchus haughtoni) demonstrate that extreme pneumaticity of the braincase may be more widespread in protosuchids than previously appreciated. CT scans reveal an endocranial morphology that resembles that of other early crocodylomorphs, in particular the non-crocodyliform crocodylomorph Almadasuchus figarii. There are, however, key differences in olfactory bulb and cerebral hemisphere morphology, which demonstrate the endocranium of crocodylomorphs is not as conserved as previously hypothesized. Our phylogenetic analysis recovers E. colberti as a close relative of Protosuchus richardsoni and Edentosuchus tienshanensis, contrasting with previous hypotheses of a sister group relationship with Thalattosuchia. Previous work suggested the inner ear has some similarities to semi-aquatic crocodyliforms, but the phylogenetic placement of E. colberti among protosuchids with a terrestrial postcranial skeletal morphology complicates paleoecological interpretation.
