Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| B. J. Shockey 1997 | Palate and muzzle not conspicuously broad, as that of E. latirostris; no bifurcation of anterior arm of upper molar lingual infolding of enamel (or fossettes with wear); pro- toloph of M2 long, giving tooth distinctive oblique appearance. Lower incisors lacking labial longitudinal groove, and canines not projecting laterally, as occurring in Morphippus imbricatus. Size similar to Rhynchippus equinus, but entolophid fossettids of lower molars absent, upper premolar anterolingual cingula absent, anteroposterior dimension of upper premolars shorter, manus tetradactyl, and third trochanter more proximally placed. Size greater than R. pumulis and R. brasiliensis. Differs from Pascualihippus boliviensis by rounded muzzle, I3 less reduced, labial upper molar fossette absent, and aterolingual cingulae of upper premolars absent. |
