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
  • M. Brunet

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.
Phylogeny of early Australopithecus: new fossil evidence from the Woranso-Mille (central Afar, Ethiopia)
  • Y. Haile-Selassie
  • Environmental Science, Geography
    Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2010
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.

"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.
New Pliocene hominin remains from the Leado Dido'a area of Woranso-Mille, Ethiopia.
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.
A new hominid from the Upper Miocene of Chad, Central Africa
TLDR
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.
Geology and palaeontology of the Upper Miocene Toros-Menalla hominid locality, Chad
TLDR
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.

TLDR
The results indicate that despite high intraspecific variation in mitochondrial cytochrome oxidase subunit II gene sequences of some hominoids, humans and chimpanzees are nonetheless significantly most closely related.
