All that is known about this animal is a fragment of a mandible complete with teeth. Its teeth were two-crested, slightly more transversal than in other genera such as Carolozittelia, but there are indications of the presence of a longitudinal crest, and even, in the third premolar, of a complete crest, not found in Pyrotherium.
Classificationedit
Griphodon peruvianus was first described in 1924 by Anthony, who considered it to be a Perissodactyl. The fragmentary fossil was found near Chicoca, along the Huallaga River. Subsequently the genus was considered a basal member of the Pyrotheres, a mysterious clade of heavy-shaped mammals from the Early Cenozoic of South America, of uncertain affinities. Other fossils attributed to Griphodon were later found near Contamana in the Loreto Province of Peru.
Paleoecologyedit
Griphodon seems to had a diet mainly composed of tough plants, which were crushed by its powerful crested teeth.
