Sahelanthropus tchadensis possibly the oldest fossil HOMINID so far found. It was described in 2002 on the basis of a skull found by Michel Brunet in the sand dunes of northern Chad. Six to seven million years old it was named ‘Toumai’ and has given rise to considerable controversy concerning its relationships. It may well be that it is neither an ancestor of chimpanzees nor humans, but a creature that was living at the same time as the split occurred between the groups.
