| Ouranopithecus macedoniensis Bonis & Melentis, 1977 |
Ouranopithecus macedoniensis, sometimes called Graecopithecus macedoniensis, is a prehistoric hominid species found in Greece and dated to the late Miocene. Based on O. macedoniensis's dental and facial anatomy, it is possible that O. macedoniensis was a dryopithecine. However, O. macedoniensis seems to be more closely related to orangutans in subfamily Ponginae while the most of Dryopithecinae are more closely related to the other great apes in Homininae and a few are considered to be outside of the ape clade altogether. One distinctive trait that Ouranopithecus shares with the humans and other modern African apes is the frontal sinus, a cavity in the forehead.
[edit] Morphology
O. macedoniensis had a large, broad face with a prominent supraorbital torus. It also had square-shaped orbits. O. macedoniensis may have had a relative large body size. O. macedoniensis's molar enamel cover was fairly thick and had low cusps. Sexual dimorphism is evident by the teeth. The male O. macedoniensis had large canine teeth with shearing lower premolars.
[edit] Diet
Based on the heavily pitted surface of the second molar of Ouranopithecus macedoniensis, it's assumed that its diet consisted of harder foods such as nuts or tubers.
