We present the results of technological and protein residue analyses lithic assemblages recovered at Pedernales-38 site (26.5°S; 69°W), located in highlands southern Andes (3380 masl). Based on a reconstruction operational chains differential representation their phases, we suggest that final production, use, maintenance, discard large stemmed projectile points occurred site. Of assemblage studied, nine (9) one end-scraper were subjected to analysis using cross-over immunoelectrophoresis...
The procurement of high-quality lithic resources is amongst the most indicative processes decision-making in archaeology early human groups peopling Americas. Directly dated deposits from quarry workshops have been absent late Pleistocene record South America. We present results excavations a translucent quartz crystal workshop that yielded radiocarbon-dated coherently layered stratigraphic shed light into behavior initial stages procurement. Based on detailed analysis context Valiente site...
We present new evidence obtained in archaeological surveys Quebrada Pedernales (3356 masl), the southern puna of Chile (26°S; 69°W). A series surface findings such as large lanceolate stemmed projectile points and geometric stones, together with chronostratigraphic artifactual data recovered excavations at Pedernales-38 site, suggest that coastal Huentelauquén groups explored inhabited Andean highlands between 10,151 9695 cal yr BP. The record is discussed it relates to known for this...
We present the results of an interdisciplinary study conducted at Pedernales-5 site, situated in Salar de Pedernales basin (26°S; 3356 masl), dated from 10,510−10,749 to 11,201−11,612 cal. BP. Unlike other Late Pleistocene and Holocene sites Andean Puna, where vicuñas ( Vicugna vicugna) were primary prey, Pedernales-5, zooarcheological assemblage consists almost exclusively flamingo (Phoenicopteridae) bird remains. Through analysis lithic bone artifacts, archeobotanical remains, pigment...
Se presentan los resultados de las excavaciones y análisis artefactos, ecofactos arte rupestre del sitio Infieles-1, Puna Atacama, Chile. Este se emplaza adyacente a un paredón ignimbrita con diversas manifestaciones rupestres. El estas pinturas grabado, junto la excavación realizada permitió identificar tres ocupaciones alfareras. La primera relaciona portadores cerámica Condorhuasi-Río Diablo Formativo Noroeste Argentina, unida que poseen referentes en modalidad estilística Punta Pueblo...
We discuss the process of human re-occupation Southern Puna (25°-27°S) during Late Holocene through a variety lines evidence, such as ceramics, faunal bones, lithic technology, sources raw materials like obsidian, and rock art, their integration with spatial analyses using least-cost paths. Our results indicate in which niches were formed puna, focused on activities vicuña hunting; exploitation sources, minerals pigments; camelid grazing; symbolic manifestations, inter-Andean circulation....
We present obsidian compositional data obtained by X-ray fluorescence analysis in the Andean highlands (25-27ºS / 68-69ºW) of northern Chile. Seventy-six samples (n=76) from three lithic sources and six archaeological sites were analyzed, covering a chronological sequence 10,000 to 500 cal BP. Compositional analyses indicate exploitation Ciénaga Redonda Cerro Manchado local as well Ona-Las Cuevas Salar del Hombre Muerto located between 200 230 km away on eastern slope Andes, northwestern...
