Sahelanthropus tchadensis is an extinct hominid species that is dated to about 7 ẹgbẹgbẹ̀rún ọdún sẹ́yìn. Whether it can be regarded as part of the Hominina tree is unclear; there are arguments both supporting and rejecting it. Another complication in its classification is that it is older than the human-chimpanzee divergence (estimated to 6.3 to 5.4 ẹgbẹgbẹ̀rún ọdún sẹ́yìn) seen in genetic data,[2] and that there are few if any specimens other than the partial cranium known as Toumaï.
