( Fig. 1C View FIG )
NEW MATERIAL. — Right M1 UM VD49.
DESCRIPTION
The right M1 UM VD49 ( Fig. 1C View FIG ) has a symmetrical outline like that of A. leptorhynchus ( Cirot & Bonis 1992). Paracone and metacone are nearly identical in size and are on more or less a same longitudinal line. A thick cingulum runs along the buccal side without any style. The protocone is situated slightly lingually relative to the middle of the crown. The postprotocone and postmetaconule cristae fade out in contact with the distal face of the metacone. There is a huge lingual cingulum forming a true cusp. There are small wear facets on buccal cusps and large wear facets on metaconule, protocone and lingual cingulum. The morphology of this M1 differs from that of the left M1 UM VBO1212 ( Peigné et al. 2014) which is more symmetrical, with both preprotocone and postprotocone cristae. But neither tooth can be firmly associated to a mandible of any named species.
