Cranial anatomy of oreopithecus

Reexamination of the 1958 skull of the late Miocene Oreopithecus bambolii revealed a cranial anatomy different from that widely accepted for this taxon. There is a sagittal crest, a high nuchal crest, a large gonial angle, and alpha high, rather vertical, occiput. This catarrhine was not a very large brained primate compared to known advanced hominoids.
