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.
|T. H. Rich et al. 2001||Distinguished from Ausktribosphenos by the M2 being markedly larger than the M1 in length and width rather than being subequal or noticeably smaller; lower molars niticeably more exaenodont (base of the crown significantly lower on labial than lingual side of tooth), and a less extensive precingulid; internal mandibular groove that cannot be differentiated into Meckelian and surangular grooves and is shallower and less extensive than those structures; mandibular foramen closer to the ventral margin of the mandible; and abscence of facets for the coronoid and surangular bones.|
