Sebilian implements were located along the Nile River at the 10–15 foot terraces. The formal characteristics of the finds indicate a development of technique that passed through three phases. • SEBILIAN I were formally akin to
Mousteroid tool-points, using a technique typical of the
levallois diorite based industry, with few
microburins present archaeologically. • SEBILIAN II and III tools were made using a technique indicative of a
microblade industry that had changed the production material to
flint with a much greater number of microburins found. The industry was re-designated SEBILIAN based on those previously classified type I, and described as crudely produced, possibly resultant of the necessities of the occasional opportunities for groups engaged in hunting activities. The dietary manifestations evidenced were of the sort expected from a semi-
sedentary population living near to the Nile river, namely fish, and much less frequently crocodile and turtle. ==References==
