Amphicynodon sp. 2

(Fig. 1D)

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). 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.
