Microwear and Plant Residue Analysis in a Multiproxy Approach from Stone Tools of the Middle Holocene of Patagonia (Argentina)

This study aims to evaluate the functionality of a sample of lithic tools from a multiproxy perspective. The artifacts come from a mid-Holocene hunter-gatherers’ occupation of the La Mesada site in Patagonia. The perspective involves the examination of use-wear traces, hafting wear, and organic micro-residues. The experimental program that supports this perspective is presented. Use-wear traces and organic residues were recognized in the distal portion of the archaeological artifacts. Meanwhile, some tools, in the proximal and middle portion, present alterations attributable to hafting in combination with animal and vegetable residues. The production sequence of a particular artifact design is discussed, with distinctive aspects regarding regional trends. Practices related to plant management were identified that allow the evaluation of mobility circuits and interchange mechanisms of these societies.
