Diagnosis
ReferenceDiagnosis
E. Cerdeño and B. Vera 2010"Medium-sized notohippid, with complete, brachydont dentition, and the following features: (1) skull long and narrow, similar to, but lower than, Rhynchippus equinus, differing from the notably wider, shorter, and more robust skull of Eurygenium and Pascualihippus; (2) sagittal crest well developed, longer than that of R. equinus and R. pumilus; (3) pterygoid processes short, slender; (4) palate narrower than R. equinus and R. pumilus, with jugal series rather parallel; (5) closed dentition, without diastemata or cement, in contrast to Notohippinae species; (6) jugal teeth without postfossette; (7) M3 with very short metaloph and lingually projected protocone; (8) upper incisors and canine subequal in size and morphology, with a lingual median vertical crest, in contrast to Eomorphippus, Rhynchippus, Eurygenium, and Pascualihippus; and (9) upper premolars and molars (at least M2) with low anterolingual cingulum."
