LITHIC TECHNOLOGY FROM LAS TOSCAS 3 SITE, PAMPEAN INTERSERRANA GRASSLANDS, ARGENTINA: USE OF LITHIC RAW MATERIALS AND ARTIFACT MANUFACTURE. In this article, the results of the study of the lithic technology of Las Toscas 3 archaeological site, located in the Interserrana grasslands in the humid Pampa subregion, Argentina, are presented and discussed. The archaeological assemblage is composed mainly of lithic artifacts, scarce faunal remains, and fragments of mineral pigment, resulting from hunter-gatherer occupations on the banks of a shallow lake. The finding of a small projectile tip allow part of the materials to be assigned to the late Holocene (c. 3000 BP), although it is not possible to rule out previous occupations. The main goal that guided this research was to establish how different lithic raw materials were exploited and to study the techniques used in artifact production. To this end, we present the results of the techno-morphological analysis of the lithic artifacts, the analysis of procurement strategies, and a description of the operating chain for each raw material. The results achieved indicate that various technological tasks were developed at the site, with the Group Sierras Bayas orthoquarzite being the most exploited rock. Although the reduction of cores to obtain blanks for the manufacture of a wide variety of tools is observed, the intermediate and final stages of the operating chain are preferably represented.
