Anthropogenic testimony dating back to the earliest traces of ancient human settlements on the border between Morocco and Algeria, with artifacts such as arrowheads and cave drawings, before the appearance of the region would change abruptly about 10,000 years ago, when the Sahara began to advance, making these areas uninhabitable.

Flint is a sedimentary rock composed almost exclusively of silica.
Silica (or even silicic anhydride, IUPAC silicon dioxide), in turn, is a compound of silicon (one of the 92 elements of the universe) whose chemical formula is SiO2.
This rock is formed in two ways:
- for the accumulation of remains of shell-like organisms or siliceous skeleton such as radiolarians, diatoms, silicoflagellates and sponges, taking the name of radiolarite or diatomite.
- by segregation and accumulation of silica, coming from terrigenous and carbonate rocks.
Flint tends to concentrate on extremely compact lenses that are almost impervious to atmospheric agents, peculiarities which, together with the relative abundance, hardness and concoid fracture made it the main material of the first lithic industries.
The flints worked are a fundamental testimony of the first human settlements, the working techniques used to create them (chipping) allow to identify different periods of prehistory. Use continued, then, until relatively recently. In the seventeenth century, knives with the blade of this material, which was also used for the tips of the arrows, were still used, especially among the peoples of the Americas.
However, it is necessary to distinguish worked flint from its natural splinters, called eolites.
Flint, as flint stone, was also fundamental for the functioning of the manual flintlocks (in Europe and in the Mediterranean basin at least since the early Middle Ages) and, from the seventeenth to the nineteenth century, also to spark the accusing mechanisms of fire, until the advent of "percussion" weapons.
