A note on an Acheulian biface from Adrar Bous, Tenere Desert, south central Sahara, Republic of Niger

Adrar Bous is an isolated Silurian ring complex located east of the Aïr massif in the Ténéré Desert of Niger. Although situated some 1500 km inland in the geographical heart of the Sahara, the valleys around the mountain have been occupied during intermittently wetter climatic interludes from Acheulian times until the mid to late Holocene. We here present the results of path form analysis of a single very symmetrical Acheulian biface from Adrar Bous. Our aim was to test the hypothesis that the Acheulian stone toolmakers had a mental template based on naturally occurring forms and had an instinctive practical knowledge of geometry.Martin Williams, Peter Glasby and John Blackwoodhttp://www.saharajournal.com/19/pages/abs_19.html#p8
