DESCRIPTION
A right M1 (UM VBO492) from Valbro ( Peigné et al. 2014: fig. 22b) has an overall pattern indicating Amphicynodon
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 View FIG ). 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.
