Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| F. Abdala and N. P. Giannini 2002 | Carnivorous eucynodonts with an overall cranial morphology similar to that of Thrinaxodon, but showing a more robust zygomatic arch, which is also conspicuously more flared laterally; characteristic angulation (c. 110 degrees or more) between the ventral edge of the maxillary zygomatic process and the anteroventral margin of the jugal; pterygoid ¯anges greatly elongated, ending in a thin projection, directed posteroventrally; osseous secondary palate posteriorly expanded; and the posterior sectorial postcanine teeth with backwardly recurved principal cusps, lacking cingula or with tiny lingual cingular cusps |
