Step-by-step explanation:
The largest extinct primate measuring over 10 feet tall and weighing 1,200 lbs was called Gigantopithecus. Gigantopithecus is an extinct genus of ape that lived from roughly nine million years to as recently as one hundred thousand years ago in what is now China, India, and Vietnam. It is believed to be the largest ape that ever existed, with some individuals estimated to have stood over ten feet tall and weighed around 1,200 lbs. Fossils of Gigantopithecus have been discovered primarily in cave deposits, and the largest number of remains have been found in southern China.
