Unfortunately, without any fossil bones from the postcranial skeleton , its locomotion cannot be unequivocally determined. This species lived sometime between 7 and 6 million years ago in West-Central Africa (Chad). claimed that this specie is oldest known human ancestor. However, they are not confirmed as belonging to the same species as the cranial remains.
The discovery of six fossils (with identification numbers starting with TM 266) was made by a team, lead by Michel Brunet, between July 2001 and March 2002. However, an Australopithecus bahrelghazali mandible was found in Chad by Mamelbaye Tomalta, Najia and Alain Beauvilain, Michel Brunet and Aladji H. E. Moutaye as early as 1995. [12] The alleged motive for this suppression of information would be that the morphology of the femur might cast doubt on the bipedalism of Toumaï.
All fossils have been recovered from Toros-Menalla in the Djurab desert of Chad, Africa. During this vast period of time our family tree grew to include many ancestors representing different species from our evolutionary past. a common ancestor of humans and chimpanzees, related to both humans and chimpanzees, but not an ancestor of either, the lack of cranial remains makes estimates difficult, but brain size is estimated at about 320-380cc (similar to that of a chimpanzee).
The size of the skull suggests the individual was a male.

PaleoAnthropology 2006:36-50. The Australian Museum respects and acknowledges the Gadigal people of the Eora Nation as the First Peoples and Traditional Custodians of the land and waterways on which the Museum stands. Even if this claim is upheld the find would lose none of its significance, because at present, very few chimpanzee or gorilla ancestors have been found anywhere in Africa. [6], Sahelanthropus ("Sahel man") was proposed as a new genus within Hominidae by Brunet et al. [18], A further possibility is that Toumaï is not ancestral to either humans or chimpanzees at all, but rather an early representative of the Gorillini lineage. This is approximately the same size as a contemporary African ape. Nature, "The look of Toumaï", 7 April 2005, pp. [1] Some palaeontologists have disputed this interpretation, stating that the basicranium, as well as dentition and facial features, do not represent adaptations unique to the hominin clade, nor indicative of bipedalism;[9] and stating that canine wear is similar to other Miocene apes. Brigitte Senut and Martin Pickford, the discoverers of Orrorin tugenensis, suggested that the features of S. tchadensis are consistent with a female proto-gorilla. It was somewhat crushed and distorted when first discovered and some of its detail had been eroded by blowing sand.

The braincase, being only 320 cm3 to 380 cm3 in volume, is similar to that of extant chimpanzees and is notably less than the approximate human volume of 1350 cm3. Ape-like features included a small brain (even slightly smaller than a chimpanzee’s), sloping face, very prominent browridges, and elongated skull. Their age at death is determined by examining their teeth and bones, and by understanding how quickly these structures develop within the bodies of our ancestors. Our species, Homo sapiens, has now spread to all parts of the world but it's generally believed that we originated in Africa by about 200,000 years ago. Other articles where Sahelanthropus tchadensis is discussed: Australopithecus: …the human lineage (hominins) include Sahelanthropus tchadensis (7–6 mya), Orrorin tugenensis (6 mya), Ardipithecus kadabba (5.8–5.2 mya), and Ar. - Walking Upright", "Palaeoanthropology (communication arising): Sahelanthropus or 'Sahelpithecus'? Important changes to the brain have been occurring for more than two million years. Adventures in the Rift Valley: Interactive, Digital Archive of Ungulate and Carnivore Dentition, Burin from Laugerie Haute & Basse, Dordogne, France, Neanderthal Mitochondrial and Nuclear DNA. As our ancestors’ intelligence increased, they developed the ability to make increasingly more complex stone, metal and other tools, create art and deliberately produce and sustain fire.
Funding for eFossils was provided by the Longhorn Innovation Fund for Technology (LIFT) Award from the Research & Educational Technology Committee (R&E) of the IT governance structure at The University of Texas at Austin. Orrorin tugenensis (6 mya) a. This website may contain names, images and voices of deceased Aboriginal and Torres Strait Islander peoples.
Thank you for reading. Existing fossils include a relatively small cranium, five pieces of jaw, and some teeth, making up a head that has a mixture of derived and primitive features. Our ancestors have been using tools for many millions of years. Sahelanthropus tchadensis was described in 2002 by French paleontologist Michel Brunet and his team. Upon examination of the foramen magnum in the primary study, the lead author speculated that a bipedal gait "would not be unreasonable" based on basicranial morphology similar to more recent hominins. Sahelanthropus tchadensis: Locomotion. A research team of scientists led by French paleontologist Michael Brunet uncovered the fossils in 2001, including the type specimen TM 266-01-0606-1.
