Abstract
Collections in early Middle Miocene deposits at Pasalar in Turkey yielded a very rich fauna. Including 2 hominoid species referred to S. darwini (Abel) 1902 and R. wickeri (Leakey) 1962. These are more primitive morphologically and earlier in time than other species of these genera. They provide evidence that Sivapithecus and Ramapithecus are closely related and that their early diversification may have occurred not in Africa but in Eurasia.
