Hippohyus
Hippohyus is an extinct genus of pig-like animals that lived during the Pliocene in India. Description. "Hippohyus" had high-crowned molars with wrinkled enamel. The posterior premolars were enlarged and short. The skull was primitive, with a flat forehead, enlarged nasal bones, a relatively central orbital cavity and a rather robust zygomatic arch, with the jugal root originating at the height of the fourth premolar. The most unusual dental characteristic of "Hippohyus" was the extraordinary folding of the cones and conules in its teeth. Its dental wear was more similar a horse than a typical pig.
