Answer:
an example of the Levallois technique of Homo erectus.
Explanation:
The Levallois technique is the name given by archaeologists to a type of stone chipped emblem, developed by the precursors of modern humans during the Paleolithic period.
From a formal point of view, the Levallois technique can be defined as a complex flaking procedure which, by means of a special preparation of the upper face of the core (and optionally of its periphery and its percussion platform) is able to preconceive or predetermined, totally or partially, the shape and size of the flake, before being extracted. Thus, lytic cleansing follows concrete steps that result in very specific formal results.
