This fossil ape was discovered in 1910 in Siwalik, northwest India, and was named after an Indian god. G. Lewis discovered a similar fossil in 1935. According to E. Simons and other scholars, Sivapithecus belongs to the broader Dryopithecidae, which were widely distributed in Eurasia and Africa from the Miocene to the Pliocene, and is said to be the ancestor of modern apes. In the 1970s, a skull fossil was discovered, and its phylogenetic relationship with the orangutan in particular became the most likely candidate.

インド北西部のシワリクで 1910年に発見され,インドの神の名をとって名づけられた化石類人猿。その後 35年に G.ルーイスが同様の化石を発見している。 E.サイモンズらの学者によると,シバピテクスは,中新世から鮮新世にユーラシア大陸とアフリカに広く分布していた広義のドリオピテクス類に含まれ,現生の類人猿の祖先であるという。 1970年代に頭骨化石が発見され,特にオランウータンとの系統関係が有力視されるようになった。
