THE first sites with Pliocene and Pleistocene mammals west of the Rift Valley in Central Africa in northern Chad were reported in 1959 (ref. 1), and documented the presence of mixed savannah and woodland habitats. Further sites2 and a probable Homo erectus cranio-facial fragment3 were subsequently discovered. In 1993 a survey of Pliocene and Pleistocene formations in the Borkou-Ennedi-Tibesti Province of Chad (B.E.T.) led to the discovery of 17 new sites in the region of Bahr el Ghazal… 

Humanity from African Naissance to Coming Millennia Chadian Australopithecines: Biochronology and Environmental Context

Five palaeontological and geological field missions carried out in the Djourab Desert (Northern Chad) by the French-Chadian Paleoanthropological Mission (MPFT) have resulted in the discovery of about

CHAD: DISCOVERY OF A VERTEBRATE FAUNA CLOSE TO THE MIO-PLIOCENE BOUNDARY

TLDR
The focus of this paper is on the environment and faunas of KB, an area of scattered dunes indicating a still older age than Kollé, and the importance of sites of this age in understanding the environments of the earliest hominids.

TLDR
The Woranso-Mille hominids show that there is no compelling evidence to falsify the hypothesis of ‘chronospecies pair’ or ancestor–descendant relationship between Au.

Le plus vieux Camelidae (Mammalia, Artiodactyla) d’Afrique : limite Mio-Pliocène, Tchad

– A fragment of mandible and two metapodials complete unearthed from the fossiliferous aera of Kossom Bougoudi (KB3 and KB26), northern Chad are described. A comparative study allows to assign these

"Lucy" redux: a review of research on Australopithecus afarensis.

TLDR
The discovery and naming of A. afarensis coincided with important developments in theory and methodology in paleoanthropology; in addition, important fossil and genetic discoveries were changing expectations about hominin divergence dates from extant African apes.

First Early Hominin from Central Africa (Ishango, Democratic Republic of Congo)

TLDR
It is shown that the size and shape of the enamel-dentine junction (EDJ) surface discriminate between Plio-Pleistocene and post-Lower Pleistocene hominins, and that the Ishango molar clusters with australopiths and early Homo from East and southern Africa.

Phytoliths indicate significant arboreal cover at Sahelanthropus type locality TM266 in northern Chad and a decrease in later sites.

Cosmogenic nuclide dating of Sahelanthropus tchadensis and Australopithecus bahrelghazali: Mio-Pliocene hominids from Chad

TLDR
A chronological constraint is an important cornerstone both for establishing the earliest stages of hominid evolution and for new calibrations of the molecular clock.
