The Age of the Sahara Desert
@article{Schuster2006TheAO, title={The Age of the Sahara Desert}, author={Mathieu Schuster and Philippe Duringer and Jean‐François Ghienne and Patrick Vignaud and Hassan Taisso Mackaye and Andossa Likius and Michel Brunet}, journal={Science}, year={2006}, volume={311}, pages={821 - 821} }
In the Sahara region, the age of onset of the desert condition has been uncertain until now. Here we report on the discovery of 7,000,000-year-old eolian dune deposits from the northern Chad Basin. This geological archive is the oldest known evidence for desert occurrence in the Sahara.

Aridification of the Sahara desert caused by Tethys Sea shrinkage during the Late Miocene

The Tortonian stage of the Late Miocene epoch is identified as the pivotal period for triggering north African aridity and creating the Sahara desert, and it is demonstrated that the African summer monsoon was drastically weakened by the Tethys Sea shrinkage during the Tortonian, allowing arid, desert conditions to expand across north Africa.

A new hominid from the Upper Miocene of Chad, Central Africa
- Environmental Science, GeographyNature
- 2002
The discovery of six hominid specimens from Chad, central Africa, 2,500 km from the East African Rift Valley, suggest that the earliest members of the hominids clade were more widely distributed than has been thought, and that the divergence between the human and chimpanzee lineages was earlier than indicated by most molecular studies.

The fauna from Toros-Menalla site 266 suggests that S. tchadensis lived close to a lake, but not far from a sandy desert, perhaps the oldest record of desert conditions in the Neogene of northern central Africa.

New dental and mandibular specimens from three Toros-Menalla fossiliferous localities of the same age are described, including a lower canine consistent with a non-honing C/P3 complex, post-canine teeth with primitive root morphology and intermediate radial enamel thickness, which confirm the morphological differences between S. tchadensis and African apes.
