Overview
Known from a mandible fragment with teeth found in Chad, far west of the East African Rift Valley. Sometimes synonymized with Au. afarensis, its main significance is geographic — demonstrating that early hominins were not restricted to the Rift Valley. Isotopic analysis suggests a diet rich in C4 plants (grasses/sedges), different from East African contemporaries.
