Abstract

The present 3D Dataset contains the 3D models produced for the paper "Szczygielski, T., Celestin, F., Adnet, S., Guinot, G., 2026. Triassic turtles of France: the first European Rhaetian stem turtle taxon (clades Testudinata, Proterochersidae). Swiss Journal of Palaeontology". The digitized material consists of shell and appendicular skeleton fragments of the first diagnostic stem turtle from the European Rhaetian and showcases a number of autapomorphic characters.
