Gigantopithecus blacki

Gigantopithecus blacki is the single species of Gigantopithecus, an extinct great ape that lived in central to southern China from about two million to roughly 215,000 to 295,000 years ago, in the Early to Middle Pleistocene. Ralph von Koenigswald identified its first remains, two molars, in a drugstore in 1935. Only teeth and four mandibles are known, from at least 16 sites, so size estimates are speculative, though it was traditionally restored as an orangutan-like ape of possibly 200 to 300 kilograms. It is now classed in the subfamily Ponginae, close to orangutans. Its molars are the largest of any known ape and have the thickest enamel.
