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.

The present 3D Dataset contains the 3D models analyzed in the publication “Systematic and locomotor diversification of the Adapis group (Primates, Adapiformes) in the late Eocene of the Quercy (Southwest France), revealed by humeral remains”. In this paper, twenty humeral specimens from the old and new Quercy collections attributed to the fossil primates Adapis and Palaeolemur are described and analysed together. In this dataset only the scans of the fossils belonging to the collections of Université de Montpellier are provided.
In our paper (Marigó et al., 2019) we provide a qualitative and quantitative analysis of the different humeri, revealing that high variability is present within the “Adapis group” sample. Six different morphotypes are identified, confirming that what has often been called “Adapis parisiensis” is a mix of different species that present different locomotor adaptations.
