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 note presents the 3D model of the hemi-mandible UM-PAT 159 of the MP7 Diacodexis species D. cf. gigasei and 3D models corresponding to the restoration of the ascending ramus, broken on the original specimen, and to a restoration of a complete mandible based on the preserved left hemi-mandible.
