Archaeohyrax is a genus of extinct, notoungulate mammal known from the Middle Eocene to Oligocene of Argentina and Bolivia.[1][2]

Description

The holotype of the type species, A. patagonicus, is a skull with a tall, blunt muzzle, and high-crowned cheek teeth. If the skull is compared to those of the superficially similar hyraxes, the remains suggest a small animal about 45 centimetres (18 in) long. Fossils of Archaeohyrax have been found in the Sarmiento, and Deseado Formations of Argentina and the Salla Formation of the Salla-Luribay Basin of Bolivia.[3]
