Document Summary
A. 5: y5 molars, broad chest (expanded thorax, suspensory locomotion with vertical climbing. Very long forelimbs: no tail, long, slender hands, robust big toe, larger brain, wide interorbital pillar. Intro notes on early apes : from late oligocene to early to middle miocene deposits of kenya and uganda = primitive ape-like catarrhines = proconsulids, called apes because not cercopithecoids. Cercopithecoids = distinct dental and skeletal anatomy: living hominoids lack derived features, difficult to distinguish basal catarrhines from basal hominoids, acted like monkeys, most like all were ancestral to nothing. Proconsulids: early middle miocene, africa only, features (for most) Great range in body size: proconsul (18 20 mya) Abducted knee built for vertical climbing (based on distal femur) Circular bottom of glenoid: equatorius (15 mya) F. 3. capable of both arboreal and terrestrial behaviors: otavipithecus (13 mya) Arboreal quadruped (middle phalanx: early middle miocene, africa only, turkanopithecus. Ulna = arboreal quadruped with some suspensory capabilities: rukwapithecus fleaglei (25 mya)
