Chororapithecus
Chororapithecus is an extinct great ape from the Afar region of Ethiopia roughly 8 million years ago during the Late Miocene, comprising one species, C. abyssinicus.The teeth are adapted for processing tough plant fibres as well as hard, brittle food, and the formation is thought to represent a forested lakeside habitat.The discoverers noted the teeth have some of the same adaptations for shearing food as those of gorillas, and classified it as the first fossil member and the only other genus of the tribe Gorillini.Based on the revised date and similarly large premolar size, the 10 million year old Kenyan Nakalipithecus has been proposed to have been the ancestor to Chororapithecus, which would move the LCA to 10 mya if correct.[1] The Chorora Formation represents a braided river system, possibly a forested area alongside a lake in a forest-savanna mosaic environment.[1] It is the only sub-Saharan vertebrate-bearing formation spanning from 9–7.4 mya, and records the earliest known occurrences of cercopithecine monkeys, hippos, and rabbits in Africa.
