The history of Senegal is commonly divided into a number of periods, encompassing the prehistoric era, the precolonial period, colonialism, and the contemporary era. Paleolithic The earliest evidence of human life is found in the valley of the Falémé in the south-east. The presence of man in the Lower Paleolithic is attested by the discovery of stone tools characteristic of Acheulean such as hand axes reported by Théodore Monod at the tip of Fann in the peninsula of Cap-Vert in 1938, or cleavers found in the south-east. There were also found stones shaped by the Levallois technique, characteristic of the Middle Paleolithic. Mousterian Industry is represented mainly by scrapers found in the peninsula of Cap-Vert, as well in the low and middle valleys of the Senegal and the Falémé. Some pieces are explicitly linked to hunting, like those found in Tiémassass, near M'Bour, a controversial site that some claim belongs to the Upper Paleolithic, while other argue in favor of the Neolithic. Neolithic In Senegambia, the period when humans became hunters, fishermen and producers (farmer and artisan) are all well represented and studied. This is when more elaborate objects and ceramics emerged. But gray areas remain. Although the characteristics and manifestations of civilization from the Neolithic have been identified their origins and relationship have not yet fully defined. What can be distinguished is: The dig of Cape Manuel: the Neolithic deposit Manueline Dakar was discovered in 1940. Basalt rocks including ankaramite were used for making microlithic tools such as axes or planes. Such tools have been found at Gorée and the Magdalen Islands, indicating the activity of shipbuilding by nearby fishermen. The dig of Bel-Air: Neolithic Bélarien tools, usually made out of flint, are present in the dunes of the west, near the current capital. In addition to axes, adzes and pottery, there is also a statuette, the Venus Thiaroye The dig of Khant: the Khanty creek, located in the north near Kayar in the lower valley of the Senegal River, gave its name to a Neolithic industry which mainly uses bone and wood. This deposit is on the list of closed sites and monuments of Senegal. The dig the Falémé located in the south-east of Senegal, has uncovered a Neolithic Falemian tools industry that produced polished materials as diverse as sandstone, hematite, shale, quartz, and flint. Grinding equipment and pottery from the period are well represented at the site.
