Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| W. K. Gregory and G. G. Simpson 1926 | Upper molars with distinct but closely approximated paracone and metacone, sublateral in position. Protocone low but well developed. No hypocone. Molars crowded antero-posteriorly, the interdental embrasures reduced to narrow fissures. P4 more or less molariform. Lower molars with three distinct trigonid cusps but with the pa'd lower than the me'd. Taloniids still large, basined, with distinct entoconids and hypoconids, occluding with the protocone only. Orbit and antorbital region of primitive type. Nasals separate. Zygomata complete. Glenoid little displaced internally. |
