Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. Stock 1937 | Rostral portion of skull slender and elongate; diastema between C and P~ similar in length to length of premolar series P2-P4 inclusive. Orbit situated not so far back as in Prosthennops crassigenis, but farther back than in Desmathyus siouxensis. Cranial length (as measured from level of posterior ends of third molars to posterior side of occipital condyles) similar to length of cheek-tooth series P2-M3, inclusive. Palate extends behind M3 for a distance slightly greater than length of third molar. Dentition ?/?, 1/1, 3/3, 3/3. In stage of acquisition of molar pattern, the premolars, particularly P4, are more advanced than in Desmathyus, less so than in Prosthennops. Crowns of molar teeth with inner cuspules and crenulations better developed than in Prosthennops. Lower premolars narrower and less molariform than in Prosthennops,re- sembling in their characters the comparable teeth in Desmathyus. P4 with shorter heel than in latter genus. |
