Sahelanthropus is an extinct genus of hominid dated to about 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 .
Sahelanthropus tchadensis is thought to be one of the earliest species belonging to the human lineage. Fossils date back to 7 million years ago. [4] The only fossils that remain are five pieces of the jaw, teeth, and a small cranium.
In 2001 the seven-million-year-old Sahelanthropus tchadensis was discovered in Chad. Based on animal finds in the vicinity, this suggests a mosaic of environments from gallery forest at the edge of a lake area to a dominance of large savannah and grassland, although more research was needed to determine this precisely.

Sahelanthropus tchadensis Hominini : The latest common ancestor of humans and chimpanzees is estimated to have lived between roughly 10 to 5 million years ago. Both chimpanzees and humans have a larynx that repositions during the first two years of life to a spot between the pharynx and the lungs, indicating that the common ancestors have this ...
