Sahelanthropus tchadensis - The Smithsonians Human Origins Program Although we have only cranial material from Sahelanthropus, studies so far show this species had a combination of ape-like and human-like features Ape-like features included a small brain (even slightly smaller than a chimpanzee’s), sloping face, very prominent browridges, and elongated skull
Sahelanthropus - Wikipedia The type species, Sahelanthropus tchadensis, was first announced in 2002, based mainly on a partial cranium, nicknamed Toumaï, discovered in northern Chad The definitive phylogenetic position of Sahelanthropus within hominids is uncertain
6. Sahelanthropus tchadensis – The History of Our Tribe: Hominini The skull of S tchadensis is very robust, with a chimp-sized brain and pronounced ape-like muscle attachments While only fragmentary postcranial material has been discovered, some researchers claim that the foramen magnum is anteriorly oriented, suggesting an upright and bipedal hominin
Sahelanthropus tchadensis - The Australian Museum In this study, CT scans were used to rebuild a more accurate picture of the skull features of Toumai Comparisons were then done with the skulls of fossil hominins, chimpanzees and gorillas using over 30 features – Toumai fell within the hominin range for all the features
Virtual cranial reconstruction of Sahelanthropus tchadensis The discovery of the skull known as Toumaï four years ago in Chad began a controversy Faunal studies suggested an age close to 7 million years; a small cranium suggested chimpanzee-like brain
Sahelanthropus tchadensis - McHenry County College The Sahelanthropus tchadensis skull was discovered by Michael Brunet's team in Chad in 2001 and described in Nature in 2002 The early date of this skull is significant in that it places it at around the time the human lineage is believed to have diverged from the ape lineage
Sahelanthropus tchadensis - Becoming Human In the Toumaï skull, the foramen magnum seems to be positioned fairly far forward, and this was interpreted by Brunet and his colleagues as indicating bipedal locomotion in Sahelanthropus
Virtual cranial reconstruction of Sahelanthropus tchadensis Here we present a detailed virtual reconstruction of the TM 266 cranium that corrects these distortions The reconstruction confirms that S tchadensis is a hominid and is not more closely related to the African great apes
