    Technological and Protein Residue Analysis on Ancient Stemmed Projectile Points of the Southern Andes Highlands
    (2024) Loyola, Rodrigo; López-Mendoza, Patricio; Carrasco, Carlos; Walker, Cam; Fagan, John; Méndez Muñoz, Víctor Andrés; Santana Sagredo, Francisca; Flores Aqueveque, Valentina; Soto, Angélica
    We present the results of technological and protein residue analyses of the lithic assemblagesrecovered at the Pedernales-38 site (26.5°S; 69°W), located in the highlands of the southernAndes (3380 masl). Based on a reconstruction of the operational chains and the differentialrepresentation of their phases, we suggest that the final production, use, maintenance, anddiscard of large stemmed projectile points occurred at the site. Of the assemblage studied, nine(9) projectile points and one end-scraper were subjected to residue analysis using cross-overimmunoelectrophoresis (CIEP). Four positive reactions to antisera of human, camelid (guanacoor vicuña) and canid (Andean fox) were recorded. The results are discussed based on thedepositional context and the structure of the archeological record. We propose that Pedernalesprojectile points were mainly used in hunting weapons to capture wild camelids during theseasonal occupation of the Andes highlands

    Unveiling Terra Incognita. An archaeological search for the first human occupations of Infieles and Pedernales salt flats (3000-4100 masl, 25 degrees-26 degrees S), Atacama Region, Chile
    (2021) Lopez Mendoza, Patricio; Carrasco Gonzalez, Carlos; Loyola Munoz, Rodrigo; Flores Aqueveque, Valentina; Santana Sagredo, Francisca; Maldonado Castro, Antonio; Martinez Rivera, Ismael
    The results of archaeological surface surveys carried out on Infieles (25 degrees 58'39' S-69 degrees 03'25 '' W) and Pedernales (26 degrees 13'59 '' S-69 degrees 07' 16 '' W) salt flats, Atacama, Chile, located at an altitude from 3000 to 4100 mast are presented. Both surveys were carried out in areas that directly connect the Arid North with the Semiarid. The surveys are part of a project that investigates areas with potential human occupations during the Pleistocene-Holocene transition and are targeted at specific sectors such as river terraces, alluvial fans, wetlands, and salt flats. The variability of the archaeological record is discussed within the framework of the regional pre-Hispanic and historic sequence, and especially within the context of the first human occupations of the salt flats.
