Sivapithecus (Siva's Ape) is a genus of extinct primates. Fossil remains of animals now assigned to this genus, dated from 12.5 million to 8.5 million years old in the Miocene, have been found since the 19th century in the Siwalik Hills in the Indian Subcontinent. Any one of the species in this genus may have been the ancestor to the modern orangutans.Some early discoveries were given the separate names Ramapithecus (Rama's Ape) and Bramapithecus (Brahma's Ape), and were thought to be possible ancestors of humans. This view is no longer considered tenable.
