  • El Arqueólogo, La Puna Y El Arriero (1976-1989)

    Open AccessPaula C Ugalde, Magdalena García et al.ARTICLEChungara2026

    Presentamos la crónica y reflexiones sobre las investigaciones arqueológicas realizadas por Calogero Santoro entre las décadas de 1970 y 1980, que lo llevaron a descubrir, excavar e interpretar las ocupaciones humanas más tempranas de la puna de la Región de Arica y Parinacota (12000 a 9500 años atrás), así como formar la primera secuencia cronológica e histórico-cultural para el Arcaico de esta zona.Este artículo es fruto de una extensa entrevis…

  • South American geoarchaeology

    Open AccessLuca Sitzia, Paula C Ugalde et al.ARTICLEGeoarchaeology2021References: 22

    In this special issue, articles include research from Argentina, Brazil, Chile, Colombia, and Uruguay, plus a special paper from the United States of America. Several of the articles are from Chilean scientists and/or focus on Chilean geoarchaeology and are intended to reflect the spirit of the symposium carried out during the Congreso Nacional de Arqueología Chilena 2018 (National Chilean Archaeology Conference). The topics, techniques, and rese…

  • Processes of Paleoindian site and desert pavement formation in the Atacama Desert, Chile

    Open AccessPaula C Ugalde, Jay Quade et al.ARTICLEQuaternary Research2020

    A distinct feature of many of the earliest archaeological sites (13,000-11,200 cal yr BP) at the core of the Atacama Desert is that they lie at or just below the surface, often encased in desert pavements. In this study, we compare these sites and undisturbed desert pavements to understand archaeological site formation and pavement development and recovery. Our results indicate these pavements and their soils are poorly developed regardless of th…

  • From the Pacific to the Tropical Forests

    Open AccessC M Santoro, Eugenia Gayó et al.ARTICLEChungara2019Cited by: 5References: 23

    The social groups that initially inhabited the hyper arid core of the Atacama Desert of northern Chile during the late Pleistocene integrated a wide range of local, regional and supra regional goods and ideas for their social reproduction as suggested by the archaeological evidence contained in several open camps in Pampa del Tamarugal (PdT). Local resources for maintaining their every-day life, included stone raw material, wood, plant and animal…

  • Late Pleistocene Fuel Management and Human Colonization of the Atacama Desert, Northern Chile

    Open AccessDelphine Joly, C M Santoro et al.ARTICLELatin American Antiquity2017Cited by: 14References: 35

    Hunter-gatherers collected and used various woody species depending on the landscape, availability of plant communities, and sociocultural considerations. With extensive paleo-wetlands and groundwater-fed oases, the Atacama Desert was interspersed with riparian woodlands that provided vital resources (fuel, water, and game) at the end of the Pleistocene in areas such as the Pampa del Tamarugal (PdT) basin. We use anthracological analyses to deter…

  • How Do Surficial Lithic Assemblages Weather in Arid Environments? A Case Study from the Atacama Desert, Northern Chile

    Open AccessPaula C Ugalde, C M Santoro et al.ARTICLEGeoarchaeology2015Cited by: 6References: 17

    Archaeological sites composed only of surficial lithics are widespread in arid environments. Numerical dating of such sites is challenging, however, and even establishing a relative chronology can be daunting. One potentially helpful method for assigning relative chronologies is to use lithic weathering, on the assumption that the most weathered artifacts are also the oldest. Yet, few studies have systematically assessed how local environmental p…

  • Análisis Tecno-Tipológico De Instrumentos Líticos Del Sitio Arcaico Temprano Ipilla 2 en Los Andes De Arica, Chile

    El estudio de la tecnologa ltica en los Andes se inici con la identificacin tipolgica de puntas de proyectil para definir secuencias cronolgico-culturales de sociedades de cazadores recolectores. Anlisis tecno-tipolgicos como el que se presenta en este trabajo, tratan de mostrar que las morfologas de instrumentos lticos no son estticas pues varan de acuerdo a su uso, mantenimiento y reciclaje. En este estudio, exploramos y caracterizamos la varia…

  • Late Pleistocene human occupation of the hyperarid core in the Atacama Desert, northern Chile

    Open AccessClaudio Latorre, C M Santoro et al.ARTICLEQuaternary Science Reviews2013

    Few archeological sites in South America contain uncontroversial evidence for when the first peopling of the continent occurred. Largely ignored in this debate, extreme environments are assumed either as barriers to this early wave of migration or without potential for past habitability. Here, we report on a rare 12–13 ka human occupation from Quebrada Maní (site QM12), a plantless, near rainless landscape (1240 m asl and 85 km from the Pacific O…

  • Ocupaciones humanas tempranas y condiciones paleoambientales en el Desierto de Atacama durante la transición Pleistoceno-Holoceno

    Open AccessC M Santoro, Daniela Osorio et al.ARTICLEBoletín de Arqueología PUCP2011Cited by: 1References: 11

    El Desierto de Atacama (Arica a Taltal, 18°-25° S), uno de los ambientes más áridos del planeta, ha sido considerado un hábitat inhóspito y, por ende, una barrera importante para los grupos de cazadores- recolectores que migraron a Sudamérica a fines delPleistoceno. Recientes datos paleocológicos y geomorfológicos, resumidos aquí, evidencian que durante la transición Pleistoceno-Holoceno (c. 17.500-9500 cal AP) algunos sectores del Atacama fueron…

  • Hakenasa Cave and its relevance for the peopling of the southern Andean Altiplano

    Open AccessDaniela Osorio, Donald Jackson et al.ARTICLEAntiquity2011Cited by: 21References: 33

    Researchers in the High Andes in northern Chile report the study of a fine cave sequence, supported by 19 radiocarbon dates. The initial occupation atc. 11 500 cal BP represents the earliest human occupation known at this altitude. The toolkit suggests a hunting (logistical) camp used to take advantage of the animals gathering in the rich wetland of the neighbourhood

  • Ocupación Humana Pleistocénica en El Desierto De Atacama

    Open AccessC M Santoro, Paula C Ugalde et al.ARTICLEChungara2011

    Sudamrica cuenta con evidencias de ocupacin humana desde los 14.600 aos calibrados a.p. (14,6 ka). Sin embargo, en el desierto de Atacama existe una notoria ausencia de ocupaciones pre-11,5 ka entre las latitudes 17 a 21 S (Atacama Norte). Esto debido, en parte, a que se ha desestimado como territorio atractivo para poblaciones de la transicin Pleistoceno-Holoceno, dadas sus condiciones actuales de extrema aridez. Sobre la base de ciertos datos p…
