TM 266-01-060-1 exhibits a set of a set of derived features, including a long low cranium with thick and pronounced supraorbital torus, a small ape-sized braincase, and relatively weak subnasal prognathism 1.This specimen preserves some teeth that show that this individual had large central upper incisors and and non-incisiform canines. However, this is hotly debated. Sahelanthropus tchadensis was described in 2002 by French paleontologist Michel Brunet and his team.

Sahelanthropus tchadensis was discovered in 2001 by a research team led by Michael Brunet, a French paleontologist, in what today is called Chad. This is one of the few early hominids found in central Africa rather than in the eastern and southern portions of the continent, and it is by far the oldest. They named their discovery Sahelanthropus tchadensis. ... Cranial capacity: 375 to 550 cc. Scientist have estimated the tchadensisâs size at slightly larger than modern chimps. Sahelanthropus tchadensis is an extinct species of the Homininae (African apes) dated to about , during the Miocene epoch. Claimed as one of the most significant discoveries in the field of human evolution, the fossils possibly represent the oldest known human ancestor after the split of the human line from that of the chimpanzees. The braincase is ape-like, with a cranial capacity similar to that of modern chimpanzees, but the facial structure, brow ridges and teeth are closer to later hominids (for example the small canines). Cranial capacity: 320â380 cm3 Cranial architecture: Only a crushed cranium and mandible. Named in July 2002 from fossils discovered in Chad. Sahelanthropus tchadensis: the facts. Sahelanthropus tchadensis is a Late Miocene fossil species that is possibly the earliest known hominin. Today, many anthropologists agree that the seven-million-year-old Sahelanthropus was an early hominid while others suggest it ⦠A hominid skulll from 6-7 million years ago.

It was discovered in Chad from deposits that have been dated by biostratigraphy to between 6 and 7 million years in age. The species, and its genus Sahelanthropus, was announced in 2002, based mainly on a partial cranium, nicknamed Toumaï, discovered in northern Chad.. Sahelanthropus tchadensis lived close to the time of the chimpanzeeâhuman divergence, possibly related to Orrorin, ⦠Skull is similar to chimpanzee, except for more human-like teeth. TM 266-01-60-1 â Sahelanthropus tchadensis Discovered in 2001 by a joint French-Chadian expedition in Chad led by Michel Brunet, this find was a surprise in many ways. The recent reconstruction of the Sahelanthropus tchadensis cra-nium (TM 266-01-60-1) provides an opportunity to examine in detail differences in cranial shape between this earliest-known hominid, African apes, and other hominid taxa.
