ANÁLISIS FUNCIONALES EN ARTEFACTOS LÍTICOS DE GRUPOS CAZADORES-RECOLECTORES EN REGIONES TROPICALES DURANTE LA TRANSICIÓN PLEISTOCENO FINAL-HOLOCENO TEMPRANO: EL ABRIGO SANTA MARTA, CHIAPAS, MÉXICO.

Use-wear studies began in the 1960s with Semenov's publication entitled Prehistoric Technology (1964). Since then, a great number of investigations have been carried out to elucidate subsistence activities based on the functionality of the artifacts. Unfortunately, in Mexico few studies have focused on this type of analysis (Elizalde & Mandujano 2000; Lewenstein 1990; Mirambell 1964). In the present study, 36 lithic artifacts associated with huntergatherer groups from Pleistocene-Holocene transition contexts (13130-12671 cal. AP) were analyzed microscopically with the aim of characterizing micropolishes and inferring functionality. [ABSTRACT FROM AUTHOR]
