Sahelanthropus is an extinct genus of hominid dated to about 7 million years ago during the Late Miocene. The type species, Sahelanthropus tchadensis, was first announced in 2002, based mainly on a partial cranium, nicknamed Toumaï, discovered in northern Chad.
The definitive phylogenetic position of Sahelanthropus within hominids is uncertain. It was initially described as a possible hominin ancestral to both humans and chimpanzees, but subsequent interpretations suggest that it could be an early member of the tribe Gorillini or a stem-hominid outside the hominins. Examinations on the postcranial skeleton of Sahelanthropus also indicated that this taxon was not a habitual biped.
