Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. L. Cifelli et al. 2014 | Small multituberculate with m1 ovoid to subrectangular in occlusal view, having mesial and distal margins of the crown gently rounded and symmetrical instead of beveled; central valley broad buccolingually; cusps of lingual and buccal rows mesiodistally aligned, conical, and well separated, with valleys between cusps extending to the level of the central valley. Most closely similar to Ctenacodon, ?Psalodon (we follow Simpson (1926) in questionably referring to Psalodon specimens preserving the lower dentition, as the genus was established on upper teeth only) , and Glirodon, but differs in having well-separated first two cusps of the lingual row (with cusp 1 the largest), and a larger cusp 1 of the buccal row that is also subequal to the other cusps of that row. |
