This area is rich in Acheulean archaeological phenomenon and vertebrate fossils (early Homo). Both Homo erectus and Australopithecus boisei are found at the circum of 1.4Ma level in Konso (www.nature.com/articles/360732a0). From the simple flake to knapping of large flake blank are found at least two areas of Konso-Gardula.
