This contribution presents the three-dimensional digital models (i.e., skull, endocast, and inner ear) of a uniquely well-preserved and nearly complete skull (MCL 4228) attributed to the Late Pleistocene giant mylodontid ground sloth Ocnotherium giganteum, discovered in the Toca dos Ossos cave (Bahia State, Brazil). This specimen was described and figured in the following publication: Pujos et al. 2026: The neotropical giant ground sloth Ocnotherium giganteum (Xenarthra, Mylodontinae) from the Late Pleistocene of Brazil: anatomy, paleoneurology, and phylogenetic relationships.

The present 3D Dataset contains the 3D models of the holotype and only specimen of Kalakocetus aurorae, a new cetacean retrieved from the Kalakot area in northwestern India. This specimen consists in a left hemimandible preserving the root of i3, p2, p4, m1 and m3 in situ. Its primitive morphology, with a tricuspid m3 morphologically intermediate between Raoellidae and Pakicetidae, makes it the first offshoot of Cetacea and provides crucial new elements to understand the setting up of the peculiar dental morphology of early cetaceans.

The present dataset contains 3D models used for illustration purposes in Schultz, J. A., Weaver, L. N., Jäger, K. R. K. & Grossnickle, D. M., 2026. Reexamining the evolutionary history of the mammalian medial pterygoid muscle. Evolution. The dataset includes 3D models based on micro-computed tomography (µCT) data of the postdentary area of the morganucodontan Morganucodon, the docodontan Docodon, the eutriconodontan Priacodon and the cladotherian Dryolestes. In addition, the dataset includes manually reconstructed schematic 3D models of the middle ear bones for the morganucodontan Morganucodon, the docodontan Docodon, the eutriconodontan Priacodon and schematic middle ear bones and a virtually rendered juvenile lower jaw of a juvenile monotreme Ornithorhynchus (based on illustrations of Zeller [1989]).

The present 3D Dataset contains the 3D models of two endocarps from the Oligocene of Baraval Quercy locality. These endocarps document new fossil genera within the Anacardiaceae family and illustrate the morphological diversity of this family during the Palaeogene. The CT-scan data were processed with ImageJ and Mimics Innovation Suite version 1.13 to reconstruct the specimens. Here we provide .stl files easy to read with the software Meshlab.
