International audience The ossiferous rift found at Camp-de-Peyre in 1976 gave remains of a cold fauna from the Middle Pleistocene period, probably Mindelian period. One of the most significant data is the presence with Reindeer, Mouflon, Collared Lemming and High mountain Vole of an Equidae with long face and short snout with slenderly measuring between 1m50 and 1m55 at the withers. This animal associates some primitive characteristics with some typically “caballine” dispositions. Emphasis is on odontologic and osteologic characters that make the distinction between horses which lived before the late rissian periods and more recent fossil horses.
