morphology. Thus UM VBO492, shares with the M1 of A. leptorhynchus ( Filhol, 1876 ) found in the locality Itardies ( Cirot & Bonis 1992 ), a similar aspect of the trigon, the presence of a metaconule and a large lingual cingulum ( Fig. 1D ). On the other hand, it is narrower distally than mesially, indicating a reduction of the distal part of the jaw. This character is present in A. velaunus and A. teilhardi , but the outline of the tooth is different, with a greater length of the buccal border in those two species. We do not know if in our material there is a lower dentition corresponding to UM VBO492 and thus we cannot assign a species name to this M1, although Amphicynodon typicus could be a possibility.
