Diagnosis
ReferenceDiagnosis
B. J. MacFadden and M. F. Skinner 1979 (Onohippidium)Horse with nasal notch that lies as far anterior as P3-P4 and as far posterior as the orbit. Nasal bones not re- tracted and remain elongate splints. Well- developed dorsal lacrimal fossa and no ven- tral malar fossa. Incisors with cement-filled cups (infidibula). Protocone oval to rounded with weak preprotoconal groove and well- developed postprotoconal valley. Lower cheek teeth with either shallow ectoflexids (externomedial valleys) and isthmuses in the permanent premolars or deep ectoflexids in the deciduous premolars and molars. Very simple enamel plications. Monodacty! metapodials.
