Ramapithecus[rAmuputhE´kus, –pith´u–] Pronunciation Key, an extinct group of primates that lived from about 12 to 14 million years ago, for a time regarded as a possible ancestor of Australopithecus and, therefore, of modern humans. Fossils of Ramapithecus were discovered in N India and in E Africa, beginning in 1932. Although it was generally an apelike creature, Ramapithecus was considered a possible human ancestor on the basis of the reconstructed jaw and dental characteristics of fragmentary fossils. A complete jaw discovered in 1976 was clearly nonhominid, however, and Ramapithecus is now regarded by many as a member of Sivapithecus, a genus considered to be an ancestor of the orangutan.
