This project presents a µCT dataset and an associated 3D surface model of the holotype of Donrussellia magna (UM PAT 17; Primates, Adapiformes). UM PAT17 is the only known specimen for the species and consists of a well-preserved left lower jaw with p4-m3. It documents one of the oldest European primates, eventually dated near the Paleocene Eocene Thermal Maximum.

Our knowledge of the external brain morphology of the late Eocene artiodactyl ungulate Mixtotherium, relies on a plaster model realized on a specimen from the Victor Brun Museum in Montauban (France) and described by Dechaseaux (1973). Here, based on micro CT-scan data, we virtually reconstruct the 3D cast of the empty cavity of the partial cranium MA PHQ 716 from the Victor Brun Museum and compare it to the plaster model illustrated and described by Dechaseaux (1973). Indeed, the specimen from which the original plaster endocast originates was not identified by Dechaseaux by a specimen number. We confirm here that the studied specimen was indeed the one described and illustrated by Dechaseaux (1973). We also reconstruct a second, more detailed, model providing additional morphological and quantitative observations made available by micro CT scan investigation such as precisions on the neopallium folding and endocranial volumes.

This project presents the 3D models of two isolated petrosals from the Oligocene locality of Pech de Fraysse (Quercy, France) here attributed to the genus Prodremotherium Filhol, 1877. Our aim is to describe the petrosal morphology of this Oligocene “early ruminant” as only few data are available in the literature for Oligocene taxa.

Here, the semicircular canals of the most aquatic seal, the rare Antarctic Ross Seal (Ommatophoca rossii), are presented for the first time, along with representatives of every species in the Lobodontini: the leopard seal (Hydrurga leptonyx), Weddell seal (Leptonychotes weddellii), and crabeater seal (Lobodon carcinophagus). Because encounters with wild Ross seal are rare, and few specimens are available in collections worldwide, this dataset increases accessibility to a rare species. For further comparison, we present the bony labyrinths of other carnivorans, the elephant seal (Mirounga leonina), harbor seal (Phoca vitulina), walrus (Odobenus rosmarus), South American sea lion (Otaria byronia).
