Sahelanthropus tchadensis is an extinct homininae species (and is probably the ancestor to Orrorin) that is dated to about 7 million years ago, possibly very close to the time of the chimpanzee–human divergence. Few specimens are known, other than the partial skull nicknamed Toumaï ("hope of life").
