while they have been implicated in large scale

elsewhere in the world? Like

Throw back to the creation of a “Levallois core”, a method of stone tool production favoured by Neanderthals. A stone is reduced down to a prepared core from which one or several preferred flakes are struck off. The other flakes were also used for simple flake tools
