A new hominid from the Upper Miocene of Chad, central Africa. Nature, 418, 752-755, 2002.
The first paper on Sahelanthropus tchadensis, dating from between 7 and 6 million years ago in West Central Africa (northern Chad). This species had a combination of ape-like and human-like features. Ape-like elements: a small brain (even slightly smaller than a chimpanzee’s), sloping face, very prominent browridges, and elongated skull. Human-like elements: small canine teeth, a short middle part of the face, and a spinal cord opening underneath the skull instead of towards the back as seen in non-bipedal apes. The research team was directed by Brunet; more than 20 scientists co-authored the paper.
