Les sites Stone Age du Parc national du Niokolo-Koba, Sénégal : synthèse des données de terrains (1982–2003)

Abstract

First investigations in the Niokolo-Koba National Park were undertaken in 1969 and conducted by the IFAN Archaeology laboratory (directed by Cyr Descamps) and the Geography laboratory with Christian Barbey, after the collection of a cupule stone by the director of the Park (A. Dupuy). The amateur prehistorian Dr. Gaillard also reported the presence of flakes in the Bafoulabé alluvium. These first collections of prehistoric tools, knapped mainly on jasper and jasper facies chert, were collected in the reworked levels of gravel under the bank (last and lowest alluvial level), in the minor bed of the Gambia (Gué de Bafoulabé) and Niokolo-Koba (at Passage du Koba and in a ravine, opposite the Niokolo camp). The surveys conducted between 1983 and 1984, and the excavation between 1982 and 2003 in the Falémé valley confirmed the identity of the geomorphological and stratigraphic scheme of the lower valley of the Falémé and the Middle Gambia at the crossing of the National Park of Niokolo-Koba. This research also allowed the observation of numerous new prehistoric sites, which confirm the previous data while showing the existence of industries in stratigraphic and geomorphological positions similar to those found in the Falémé valley. A final visit inside the Park in 2003 allowed to precise the GPS coordinates of the former manual locations (between 1982 and 1986). Three Stone Age periods were identified: the Acheulean, the Middle Stone Age, formerly known as the Mousteroid, and the Later Stone Age, formerly known as the Advanced/Final Palaeolithic. The present work takes up previous data presented in mission reports or master's theses in order to place Niokolo-Koba National Park in the major issues of West African prehistoric settlements.
