Technological continuity and change through time at Area 7. (A) Elements of technological continuity (grey) and change from the Acheulian (blue) to the MSA (red), with mean debitage size and edge length to mass (EL/M) ratios on the right. (B) Changes in raw material use and cortex types through time, and (C) density plots showing artefact size distributions compared with an experimental dataset78.
