Human bones, perfectly preserved in African sand, stick out directly from the ground, and the paleontologist-archaeologist noticed from the car, approaching the cemetery. For the first time in 2003, scientists returned to Niger, in the Gobero region, and over the past five years, they found about 200 Stone Age graves. It is the results of the study of these 67 burials and the numerous bones and artifacts found both in these graves and in their environs.

As it turned out, the bones of people belonging to two cultures at once lie in Gobero.

The first, about 10 thousand years ago, came here as tribes of strong people, hunters, and fishers, which scientists attributed to the Kiffin culture. Just two millennia earlier, the last ice age ended, the Earth entered the Holocene, and the Sahara, which has remained a dry desert for many thousands of years, was filled with water and life. There was a small lake in Gobero, which, according to archaeologists, attracted people. At the bottom of the lake, there were many shells of bivalve mollusks, which people of the Stone Age ate, and in its waters, up to 8 meters deep, there were turtles and fish, including relatives of the giant Nile perch, whose length reached 1.5–2 meters.
