Pascualihippus is an extinct monotypic genus of notoungulate belonging to the family Notohippidae. It lived during the Late Oligocene, in what is now Bolivia.
This genus is primarily known from a skull and a few postcranial bones, and it likely was about the size of a sheep. Pascualihippus had a high skull, with a broad, blunt muzzle, with the two first incisors forming a transverse line across the anterior part of the premaxilla, followed by a narrowing of the muzzle when viewed from above. These characteristics are somewhat similar to those found in Toxodontidae, such as Adinotherium and Nesodon. However, its incisors had roots and the cheek teeth were quite different from those of "true" toxodonts. The molars of Pascualihippus lacked the typical bifurcation on the central loop. The premaxillary dental arch was linear, indicating that it likely was a grass bruiser. Unlike its relative Eomorphippus, its incisors were not protruding.[1]
