Quartz Arrowheads from the early late Holocene in Senegal
The operational sequence begins with the detachment of small flakes (max 2 cm long) from homogeneous quartz. Subsequently the margins of the arrowheads were retouched. In a further step the upper face was covered with flat retouches. The lower face may completely plain or was also covered by flat retouches, sometimes only over a limited part of its surface.
Human groups mainly practiced hunting and fishing in a more or less wooded savannah environment. Cattle breeding, which appeared during the 7th millennium BC, was then extended to the entire Taoudenni basin. The Ténérian-see 1019 and here: 1368 is a typical complex of such pastoral societies, although there is much variably, regarding raw material and artifactual composition.
At the turn of the second millennium BC, the aridification of the climate intensified and the current climatic conditions are progressively taking place: a long dry season, interrupted in summer by two months of rains linked to the West African monsoon.
From the second millennium BC, the sites are nevertheless fewer in the Sahara than in the Sahel. The occupation is also becoming denser south of Sebkha in Mauritania, around the inner Niger Delta and in the Gao regions of Mali and the Niger river valley.
The hypothesis most commonly used to explain this phenomenon is that the aridification of the climate would have led the Neolithic societies of the Sahara to migrate to the current Sahelian zone.
