(1) Levallois Technique for detaching Oval and Circular Flakes: Made on medium sized oval or circular lump of stone, this technique is also known as ‘Tortoise core techniques’. The dorsal surface of a typical tortoise core is prepared by centrally directed preparatory flakes, which form a hump in the centre. The striking platform is prepared at one of the ends by removing small chips or facetes (Fig.8). The applied blow on the striking platform in this case result in the breakage of circular or oval flake depending on the form of the core and the placement of the hump on the core.
