2012). The anterolophid is labiolingually short with a rounded mesial border, and the neolophid is long and straight. Between them is a small and round fossetid. From the protoconid area, lingually arises the metalophulid II and distally an oblique ectolophid. Between the neolophid and metalophulid II is a straight and labio-lingually very long labial flexid. A lingual spur of the ectolophid and a labial widening lingual portion of the metalophulid II could represent a mesolophid’s lingual and labial portions. A central S-shaped fossetid separates these two structures. The hypoconid area is a little more lingual with respect to the protoconid area. The hypolophid is straight, and the posterolophid is long and distally convex. The hypoflexid is similar to that of other lower teeth, with the shape of a narrow “V”, and its apex faces the hypolophid. The posteroflexid is thin, slightly convex, and still lingually open on LA 4300. This general morphology is similar to the dp4 of some specimens of

In occlusal view, the hypoflexus is continuous with the parafossette (as in

in similar wear stages, the tooth is smaller, and the crests are relatively wider. The anteroloph is mesially broken. The protoloph is long and widens on the labial side. The third crest in position (mesoloph?) is long and straight. The metaloph is wide and relatively long and is attached to the posterloph. This posteroloph is shorter and narrower than the others.
