Ardipithecus kadabba
Teeth and Jawbones Only - 5.8-5.2 Million Years Ago
Eleven specimens of this species have been found in the Middle Awash Valley in Ethiopia. It is thought that they comprise at least five individuals. Jawbones and teeth indicate a separate species from A. ramidus rather than a subspecies. Although ape-like features such as thick tooth enamel and large canines are apparent, morphologies such as hominin-like upper premolars, molars larger than those of chimpanzees, and a perihoning complex between the upper canine and the third lower premolar, are also present and suggest divergence away from pre-human apes and along the hominin line.
