he aim of this paper is to present the results of complementary studies on a type of lithic tool: the small wedge,trying to understand their use and, particularly, the kind of worked material during Late Holocene times in thecentral region of Argentina (ADR archaeological site). FT-IR spectroscopy on residue recovered from tools edgesurfaces and functional analysis of microwear were used as a crosscheck methodology for integrated analysis,including some experimental data. According with the analytical results, we propose that this type of instrumentwas used either as a controlled way to split camelid phalanges to use them as raw material for tool manufactureor marrow extraction.
