Taxonomy
Gigantopithecus bilaspurensis was named by Simons and Chopra (1969). Its type specimen is Chandigarh-Yale Project No. 359/68, a mandible (both horizontal rami of mandible joined at symphysis containing left C, P3, M 1 3 and posterior half right C, P3.4, M ^ .), and it is a 3D body fossil. Its type locality is Haritalyangar, North, which is in a Miocene terrestrial horizon in the Dhok Pathan Formation of India.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. L. Simons and S. R. K. Chopra 1969 | Mandible smaller in absolute size than small-
est known G. blacki, but showing relatively even smaller anterior teeth. Teeth preserved (C through M3) are little worn and lack characteristic polycuspidation of unworn G. blacki teeth. In this cusp simplicity these teeth resemble some Dryopithecus, for in- stance most D. sivalensis and D. indicus. Unlike G. blacki molars 5 or the large molar of D. indicus from Alipur, India, GSI D-175 ; lower molar protoconid distinctly smaller than metaconid, and apices of lower molar cusps more laterally placed— such a dis- tinction also separates most Dryopithecus from Ramapithecus. Teeth much less hypsodont than G. blacki. Resembles Ramapi- thecus punjabicus, G. blacki, and most hominids in having lingually and labially expanded cheek tooth occlusal faces so that sides of teeth are oriented in a more nearly vertical plane, not rounded out as in most Dryopithecus species and G. blacki. Molars not strongly divided into trigonid and talonid portions by a lingual indentation between metaconid and entoconid as is typical of G. blacki. |
