Reconstructed skull of Sivapithecus (also known as Ramapithecus), a genus of extinct primates, dating from 12.5 million to 8.5 million years ago, in the Miocene era. The original of this one was found in Potwar Plateau, Pakistan. Ramapithecus fossil bones were first excavated from Miocene deposits in Pakistan in the 1930s by George E. Lewis. Until the 1970s and 1980s they were considered to be the ancestors of the apes and modern man. This view has been overturned and Ramapithecus is now considered to be the ancestor of the orang-utan.
