From the article in Nature: "Since 2001, the Mission Paléoanthropologique Franco–Tchadienne (MPFT), a scientific collaboration between Poitiers University, Ndjamena University and Centre National d'Appui à la Recherche (CNAR) (Ndjaména), has recovered hominid specimens, including a nearly complete cranium, from a single locality (TM 266) in the Toros-Menalla fossiliferous area of the Djurab Desert of northern Chad (Table 1). The constitution of the associated fauna
suggests that the fossils are older than material dated at 6 Myr from Lukeino, Kenya8, 9. Preliminary comparison with the fauna from the Nawata formation at Lothagam, Kenya12, 13, suggests that the fossils are from the Late Miocene, between 6 and 7 Myr old. All six recovered specimens are assigned to a new taxon that is, at present, the oldest known member of the hominid clade."
