What is the defining feature of a Levallois core?

The defining feature of a Levallois core is that it is a prepared core from which multiple flakes are systematically removed. This technique involves shaping a stone core through the deliberate removal of smaller flakes to create a striking platform, allowing for the production of uniformly sized and shaped flakes. The Levallois method is significant in prehistoric archaeology as it reflects advanced cognitive skills in tool-making, demonstrating the ability to plan and execute complex strategies for flake production.

This technique contrasts with other methods that might focus on producing flakes with less planning or that do not necessarily yield multiple usable tools from a single core. The Levallois approach symbolizes an important step in the evolution of human tool-making capabilities, highlighting an understanding of the material properties of stone and the mechanics of flake production.
