Chad, cradle of humanity ?

With Australopithecus bahrelghazali (Abel) and Sahelanthropus tchadensis (Toumaï), two hominids fossils, Chad is the potential cradle of humanity

Mandibular symphysis of the Hominid of KT40

KT40 mandibule site

Australopithecus unearthed 18 July 2000 to 40 KT per Fanoné Gongdibé (photographes Alain Beauvilain).

Like for Abel, it is a mandibular symphysis but with only two teeth. But, this time, the teeth were subjected to surface erosion, the mandibular symphysis being in the sand. As Australopithecus bahrelghazali, observation immediately shows the three roots of the premolar. Sieving is performed unsuccessfully, the fragments of teeth having been windswept since a time. The discovery of a jaw fragment of a suidea lets say that the site is comparable to KT 12 and 13 KT.

When in September in Paris, we gave this fossil to Michel Brunet, he made this comment: "Congratulations, you found the female!"

18 July 2000 at the meridian time, screening of the site where a mandibular symphysis of hominid has been unearthed (photograph Alain Beauvilain). From left to right, Fanoné Gongdibé, Ahounta Djimdoumalbaye Mahamat Adoum (in the background).

On the way back from a mission on Kollé's sites, Mission whose objective was to bring back sediment so that it is washed and sorted in N'Djamena in the prospect to grow the collection of micro-rodents unearthed on these sites, Alain Beauvilain drives again the team on the sites of KT12 and KT13 in order to monitor and possibly collect new hominid fossils that have been put in the day by the first rains of July 2000. Then, convinced that the foot of Goz Kerki must possess other sites of hominids, he stops vehicles at random at the foot of the cord to the place that will become KT40. As soon as he leaves the vehicle, Fanoné Gongdibé finds this jaw fragment.

Although it is the meridian time, sifting is undertaken immediatly without success, teeth chips have already been swept away by the wind.

With three hominid sites, the feet of Goz Kerki, and of other sandy cords of same origin that prolong it, deserve the systematic prospecting.
