Gigantopithecus blacki, of the family Hominidae (traditionally placed in Pongidae), is an extinct ape from the Early to Middle Pleistocene of Asia, known only from fossilized jawbones and teeth. Remains have been found in southern China, Thailand, Vietnam, and Indonesia. Dutch anthropologist Ralph von Koenigswald named the animal in 1935. Gigantopithecus was once argued to be a member of the human subfamily Homininae, but is now usually placed in the orangutan subfamily Ponginae.


Speculative depictions of Gigantopithecus have traditionally shown a massive, gorilla-like ape, potentially 200–300 kg (440–660 lb) when alive. It primarily lived in subtropical to tropical forest, and went extinct about 300,000 years ago, likely due to climate change and the retreat of preferred habitat, and resource competition with Homo erectus.

Cryptozoologists have speculated that the yeti is a surviving descendant of Gigantopithecus.

Gigantopithecus in State of Jefferson[]

Gigantopithecus, an extinct Asian ape, was believed to be a possible ancestor of the sasquatches of modern North America. Other paleobiologists favored Homo erectus, whose range had been much closer to home. Bill Williamson really didn't care about the matter.[1]
