Ouranopithecus
Ouranopithecus is a genus of extinct Eurasian great ape represented by two species, Ouranopithecus macedoniensis, a late Miocene hominoid from Greece and Ouranopithecus turkae, also from the late Miocene of Turkey.Systematics
Based on O. macedoniensis' dental and facial anatomy, it has been suggested that Ouranopithecus was actually a dryopithecine. However, it is probably more closely related to the Ponginae. Some researchers consider O. macedoniensis to be the last common ancestor of apes and humans, and a forerunner to australopithecines and humans, although this is very controversial and not widely accepted. It is true that O. macedoniensis shares derived features with some early hominins, but they are almost certainly not closely related species. It has been suggested that it may be a synonym of Graecopithecus freybergi, although there is not enough data to support the synonymy.
