Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| W. Sanders et al. 2004 | Same as type species:
Diminutive deinotheres; teeth smaller than homologs in Prodeinotherium and Deinotherium (Fig. 6). Differ from deinotheriines (Deinotherium and Prodeinotherium) in the following features: P3 with bunodont cusps that are more independent in occlusal distribution and that crowd the trigon basin, and with a weakly formed ectoloph; m2 with poor expression of cristids; m2, m3, and M3 with incipient development of a tritoloph(id). Distinguished from barytherioids (Phosphatherium, Daouitherium, Numidotherium, Barytherium, all with bilophodont molars) by development of the m2 distocristid into an incipient third lophid; by development of a postentoconulid in m3; by greater expression of lingual cusps in P3 (shared with other deinotheres); and by the bunodont (P3) and bunolophodont (molars) condition of cheek teeth. |
