An adult maxilla and partial mandibles of a hominoid primate recovered from the late Miocene locality of (Corakyerler (central Anatolia) are recognized as a new species of Ouranopithecus, one of the rare western Eurasian hominoids to have survived well into the late Miocene. This species is distinguished from its sister taxon, and likely ancestor Ouranopithecus macedoniensis, by a constellation of dentognathic features. The new species, in which the male postcanine dentition is larger than that of any other Miocene ape besides Gigantopithecus, is associated with evidence indicating an open, dry environment. Dental features of Ouranopithecus apparently evolved in parallel with later Australopithecus, and suggest that Ouranopithecus was adapted to a diet of tough/abrasive foods.
