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.

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.

Megatherium americanum MNHN.F.PAM276 View specimen

M3#14 This model corresponds to a virtually reconstructed bony labyrinth of the right inner ear of the skull MNHN-F-PAM 276, attributed to the extinct giant ground sloth Megatherium americanum. The fossil comes from Pleistocene deposits at Rio Salado (Prov. Buenos Aires, Argentina). The bony labyrinth of Megatherium shows semicircular canals that are proportionally much larger than in the modern two-toed and three-toed sloths. The cochlea in Megatherium shows 2.5 turns, which is a rather high value within Xenarthra. Overall, the shape of the bony labyrinth of Megatherium resembles more that of extant armadillos than that of its extant sloth relatives. Type: "3D_surfaces" doi: 10.18563/m3.sf14   state:published
