2 Africa Geological Age: Early Pliocene Years: 6 to 7 million years ago 2. Geographical Area of the Early Hominids: 1. Hominoid-Hominid Stage: Orrorin tugenensis GEOGRAPHIC AREA : KENYA, EAST AFRICA GEOLOGICAL AGE: 6 MYA The shape of the femur of Orrorin tugenensis (a) and its reconstruction (b) indicates that when on the ground probably had bipedal locomotion but the phalanges (not shown here) indicate that also retained its arboreal features. (a) (b) 1. Hominoid-Hominid Stage C. Ardipithecus ramidus GEOGRAPHIC AREA : ETHIOPEA, EAST AFRICA GEOLOGICAL AGE: 5. 2 to 5.8 MYA Premolar and mandible, and long bones: biped on the ground and arboreal on the trees.
