Document Summary
Miocene great ape genera: proconsul: e/m miocene, 23-14 mya, se europe, multiple species, 17-55 kg - africa, afropithecus: e/m miocene, 50 kg, sivapithecus: m/l miocene, 15-7 mya, 75 kg, west asia/india. Lufengpithecus: late miocene, 9-6 mya: 50 kg, china, gigantopithecus: late miocene m. Pleistocene, 9 0. 3 mya: 225 kg b. India china: dryopithecus: m/l miocene, 14-7 mya, sahelanthropus: late miocene, 7 mya, 15-45 kg, europe, ouranopithecus: late miocene, 10-9. Mya: 100 kg, africa, orrorin: late miocene, 6 mya, africa. Cranial, mandibular, and dental characteristics of extant apes. Postcrania only well known for proconsul and dryopithecus. Lacks extant ape postcranial apomorphs: intermembral index = 87, no pectoral limb elongation, manus lacks elongation and curvature of metacarpals and phalanges palmigrady, carpus (wrist): long styloid process of ulna (monkey-like) Helps stabilize the wrist to put more weight on the forelimb. Proconsul is thought of as a generalized arboreal quadruped like monkeys, not a brachiators.
