R. Ziegler et al. 2007I sup. not fissident; upper molars broad with strongly emarginated distal margin and relatively narrow hypoconal flange, distal cingulum interrupted at the deepest point of the distal emargination; i inf. bicuspulate; a1 reduced in size as compared to p4, m1-2 relatively broad with shallow hypoflexid, relatively short talonid, weak entoconid and low or moderate entocristid; labial basis of m1 strongly inclined disto-ventrally in labial view; m3 talonid reduced in size and morphology; condylus with narrow and high interarticular area and broad lower articular facet (in lingual view ending in line with distal margin of internal temporal fossa). Coronoid process somewhat tilted laterally, condylus medially.
