Hippidion
Taxonomy
Hippidion was named by Owen (1869). It was considered monophyletic by Prado and Alberdi (1996).
It was corrected as Hippidium by Cope (1881) and Lydekker (1894); it was considered a nomen dubium by Alberdi and Prado (1992) and Alberdi and Prado (1993).
It was assigned to Equinae by Hay (1902) and Gidley (1907); to Equidae by Owen (1869), Cope (1881), Lydekker (1894), Scott (1913) and Carroll (1988); to Pliohippina by Prado and Alberdi (1996); and to Equini by Prothero and Schoch (1989), Kelly (1995) and MacFadden (1998).

Diagnosis
Reference | Diagnosis | |
---|---|---|
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. |
