We conducted DMTA [2] on shearing and grinding facets (Fig. 2) of the proto-cone and protoconid/hypoconid of molars first in extant rhinoceros. We built a database with 62 wild shot specimens distributed in the five living species. Then, we used this database to infer the diet of the three fossil samples of Stephanorhinus from France (Fig. 3). All specimens (extant and fossils) are kept in various European museum collections.
