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 .
Ape skeletons. A display at the Museum of Zoology, University of Cambridge.From left to right: Bornean orangutan, two western gorillas, chimpanzee, human. The evolution of human bipedalism, which began in primates approximately four million years ago, [1] or as early as seven million years ago with Sahelanthropus, [2] [3] or approximately twelve million years ago with Danuvius guggenmosi, has ...
The chimpanzee–human divergence likely took place around 10 to 7 million years ago. [1] The list of fossils begins with Graecopithecus, dated some 7.2 million years ago, which may or may not still be ancestral to both the human and the chimpanzee lineage.

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.
Humans (genus Homo) may have descended from australopithecine ancestors and the genera Ardipithecus, Orrorin, Sahelanthropus, and Graecopithecus are the possible ancestors of the australopithecines. [12]
Panina is one of two subtribes of tribe Hominini; the other is Australopithecina (or Hominina). The genus Sahelanthropus lived around the time of the divergence, and may have then been found among one of these groups: a member of either branch of lineage; a precursor to both lineages; or possibly an early member of tribe Gorillini, which previously had split from the human-chimpanzee lineage.
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.
