Microlith

 

a small stone tool, sometimes of geometric shape (triangle, trapezoid, lunate). Microliths became widespread in the Mesolithic period in many regions of Africa, Europe, and Asia; they were also used in the Neolithic. In the USSR they have been found in the Crimea and other parts of the Ukraine, in the Lower Volga region, in Middle Asia, and in Kazakhstan. Microliths were used as arrowheads, or they were inserted into the grooves of bone and wooden implements, thus forming a flint cutting edge.
