New Material of the Hominoid Ouranopithecus macedoniensis from the Late Miocene of the Axios Valley (Macedonia, Greece) with Some Remarks on Its Sexual Dimorphism

摘要: New hominoid teeth from the late Miocene locality Ravin de la Pluie (RPl) of Axios Valley (Macedonia, Greece) are studied in this article. Their morphology, dimensions and proportions similar to Ouranopithecus macedoniensis, allowing their attribution taxon. The material provides some new morphological characters for female P3 (small asymmetry, small mesiobuccal crown projection, paracone higher than protocone) lower canine (mesial groove: large male female, distobuccal fovea: male). enriches collection O. macedoniensis. estimated degree sexual dimorphism RPl calculated by multivariate size method, is compared with those extant hominoids (Gorilla, Pan, Pongo) Lufengpithecus lufengensis China, which considered as more dimorphic any living hominoid. results suggest that premolar, molar post-canine row Pongo Lufengpithecus, slightly Gorilla clearly Pan. Therefore, macedoniensis apparently one most sexually assemblage monospecific.
