Description
Stone production debris (debitage) is the most common artifact type found at archaeological sites in North America. A significant time investment is required to catalogue debitage from large assemblages. Conventional thought holds that, because lithic tool manufacture is reductive, the attributes of flake size and cortex amount will decrease throughout production while dorsal flake scars increase. Dorsal scar count is an attribute commonly used to infer trends in an assemblage; however, the statistical significance of dorsal scars as a measure of the stage of lithic tool production has not been addressed adequately. Cortex amount is also used to deduce lithic reduction stages; however, the author argues that this may not represent behavioral patterns as meaningfully as platform morphology.
