Résumé
West Africa is a centre of domestication for pearl millet, but the spread of agricultural practices across the region remains poorly constrained. This is the result of the limited application of macrobotanical studies from controlled excavations paired with the use of absolute dating methods. This paper presents the results from a sampling excavation from Gnith, northern Senegal. The site is situated overlooking Lac de Guiers, a region known for its prehistoric tumuli, but one that has not previously undergone controlled excavation. Sampling at the edge of a potential habitation site recovered a dense macrobotanical assemblage, dominated by pearl millet, alongside ceramic pieces from a horizon dating to cal. AD 130-237. These results help illuminate the westward spread of agricultural domesticates, marking the first presence of pearl millet beyon the Middle Senegal Valley in the context of increased regional aridification
