Indopithecus
[1] However, George Edward Lewis in 1937 decided that Pilgrim's taxon was not congeneric with Dryopithecus and instead referred the molar to the co-eval ape Sivapithecus indicus.[2] Gustav Heinrich Ralph von Koenigswald in 1950 recognized D. giganteus as being distinct from Dryopithecus and Sivapithecus and erected a new genus for it, Indopithecus ("ape from India").[3] Szalay and Delson (1979) found similarities of the Indopithecus material to Gigantopithecus and synonymized the two genera, treating I. giganteus as a referred species, G.[4] However, recent authors, including David Cameron (2001, 2003), Pickford (2010), Patnaik (2014), Begun (2015), and Welker et al. (2019), have argued that Indopithecus should be treated as generically distinct in its own right.[5][6][7][8][9][10] Gigantopithecus bilaspurensis was erected by Elwyn LaVerne Simons and Chopra (1969) for paired lower jaw bones and teeth from deposits in the Siwalk Hills of India dating to approximately 6 to 9 million years ago in the Miocene, specimen Chandigarh-Yale Project No.
