Overview

The earlier and earlier and more basal species of Ardipithecus, known from teeth, a partial mandible, hand bones, foot bones, and a clavicle. A toe bone suggests bipedal locomotion. Originally described as a subspecies of Ar. ramidus but elevated to species status based on more basal dental features, particularly the larger and more ape-like canines.
