If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|D. M. Kermack 1982||A tritylodont having I3 absent; uppr postcanine teeth with only two main cusps in each of three longitudinal rows; small accessory cusp present at the medial end of the central row. Upper postcanine teeth markedly broader than long, breadth/length ratio close to 1.5. Distinguished from all other tritylodonts except Stereognathus by having no more than two principal cusps in each longitudinal row of cusps in the upper postcanine teeth: distinguished from Stereognathus by the much greater breadth/length ratio of these teeth and by the presence of a small accessory cusp in the upper postcanines.|
