PART A Match each of the pre-australopithecines described below to its corresponding description. Sahelanthropus tchadensis _____ 1. I lived about 6 mya in eastern Africa. My femurs had long necks with grooves for my obturator externus muscles. Orrorin tugenensis _____ 2. I lived about 7-6 mya in central Africa. I had a small cranial capacity, large brow ridge, and anteriorly positioned foramen magnum. Ardipithecus ramidus _____ 3. I lived about 4.4 mya in eastern Africa. I had long arms and fingers and a relatively short, broad pelvis.
