The 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 the central region of Argentina (ADR archaeological site). FT-IR spectroscopy on residue recovered from tools edge surfaces 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 instrument was used either as a controlled way to split camelid phalanges to use them as raw material for tool manufacture or marrow extraction.
