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. When 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, Agua de la Piedra, and Deseado Formations of Argentina and the Salla Formation of the Salla-Luribay Basin of Bolivia.^[3]^[4]
