Molluscan Shell Knives and Experimental Cut-Marks on Bones

Abstract

AbstractAbstractExperimentation demonstrates that the retouched edges of molluscan shells can be used effectively as butchery knives in the absence of lithic raw materials and leave striations on bone surfaces that may be indistinguishable from cut-marks made by stone knives. The potential of such non-lithic cutting tools suggests one new possible category of early artifact, and may explain the presence of cut-marks on fossil bones in paleoenvironments where stone artifacts were absent or rare.
