Constraints on Levallois core technology: A mathematical model

Recent volumetric definitions of Levallois core technology are amenable to mathematical modelling. We present a simple geometric model that permits co ntrolled manipulation of a few of the key parameters defining Levallois cor e morphology. The models indicate that Levallois cores are relatively effic ient at minimizing raw material waste while at the same time maximizing pro ductivity in terms of total number of tool blanks and amount of cutting edg e produced. Deviations from an ideal Levallois geometry produce significant declines in both efficiency and productivity. These results implicate mech anical and economic constraint sas factory underlying the broad geographic distribution and temporal persistence of Levallois core technologies during the Middle and late Pleistocene.
