Gigantopithecus blacki, an extinct ape species, stood nearly 10 feet tall and weighed up to 1,200 pounds. It inhabited the dense forests of Southeast Asia during the Pleistocene epoch. Known for its massive jaw and large molars, G. blacki likely consumed a diet of bamboo and other tough vegetation.

Gigantopithecus blacki, commonly known as G. blacki, is believed to have been native to Southeast Asia. Its fossil remains have been predominantly found in parts of southern China, specifically in the Guangxi, Guangdong, and Sichuan provinces, as well as in northern Vietnam and Thailand. These regions are characterized by their historical monsoon-influenced warm and humid environments.

The typical habitat of G. blacki is thought to have been subtropical or tropical forests, which were prevalent in the aforementioned regions during the Pleistocene epoch. These forests provided dense vegetation and a warm, humid climate. The environment would have been rich in fruit-bearing trees, bamboo, and other plant life, ideal for a large herbivorous primate.

G. blacki likely occupied an ecological niche similar to that of modern-day herbivorous primates, with a diet primarily consisting of fruits, bamboo, and other vegetation. Its large size suggests it could have played a role as a dominant browser in its ecosystem, influencing the vegetation structure and seed dispersal processes in these ancient forests. The species' adaptations to this niche may have included specialized dentition for processing tough plant material.
