Blank Form and Reduction as Determinants of Mousterian Scraper Morphology

Abstract

Variation in the forms of Mousterian tools has been attributed to a number of factors, including style, function, and more recently, differential reduction. This study compares the influences of two factors, reduction and the shapes of tool blanks, on the forms of scrapers from a Mousterian site in Italy. In the subject assemblages, the shapes of the tool blanks had a much stronger influence on scraper forms than had reduction. To the extent that blank form affects typology in other cases, explanations of contrasts among Mousterian assemblages would need to account for the use of alternative techniques of flake production. Since typological variation is multicausal, it would also appear more profitable to focus directly on variables pertinent to current research issues, rather than on reinterpreting the typology.
