Ramapithecus Late Miocene and early Pliocene ape, known from fragmentary fossils from E. Africa, south-eastern Europe, and northern India and Pakistan, dating from 14–10 Ma ago, and apparently identical or very similar to the E. African Kenyapithecus. Ramapithecus is regarded by many as transitional between the true Miocene apes (the Dryopithecinae) and the later Hominidae. If this is so, then the human and ape lines diverged prior to the late Miocene, 15–25 Ma ago. More recent evidence, however, suggests that Ramapithecus and the related or identical Sivapithecus are nearer to the evolutionary line that led to the orang-utan.

Ramapithecus A middle to late Miocene ape, known from fragmentary fossils from E. Africa, south-eastern Europe, and northern India and Pakistan, dating from 14–10 Ma ago, and very similar to the E.

Ramapithecus A genus of extinct primates that lived about 12–14 million years ago. Fossil remains of ramapithecines have been found in India and Pakistan, the Near East, and East Africa. Early discoveries of jaw fragments suggested that they chewed from side to side and had fairly short muzzles, both of which are humanoid features. However, subsequent finds, including a complete jaw, were not hominoid, and ramapithecines are now regarded by many authorities as ancestral to the Asian great apes (e.g. orang-utans), not the hominids. See also Dryopithecus; Australopithecus.

Ramapithecus a fossil anthropoid ape of the Miocene epoch, known from remains found in SW Asia and East Africa, and probably ancestral to the orang-utan; it is named from Rama + Greek pithēkos ‘ape’.
