LightDark Institute for Hominin Paleoanthropology

Sahelanthropus Tchadensis was an extremely early bipedal hominin that lived around 6-8 million years ago, thats roughly 7 million years ago. Pan-Hominin split roughly 6-9 or 7-8 million years ago.

Anatomy

Cranium

Sahelanthropus Tchadensis had a relatively small sized cranium with the foramen magnum (Where the spine connects to the cranium) more anterior than other great apes suggesting early bipedalism. S. Tchadensis had a cranial capacity of roughly 360-380 cc while Pan Troglodytes (Chimpanzees) have 275-500 cc (roughly 400 cc). S. Tchadensis had a small sagittal crest and a large nuchal crest (Probably males). They also had a large ape-like Supraorbital torus

Dental

Sahelanthropus Tchadensis had 32 teeth, that is:

• 8 Incisors
• 4 Canines
• 8 Premolars
• 12 Molars

Genetics (Hypothetical)

Sahelanthropus Tchadensis likely had 48 chromosomes like all other great apes (Excluding Humans)
