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