Desde la década del ’80, ha sido profundamente abordada desde disciplinas relacionadas con la geología y geomorfología. Desde una perspectiva arqueológica, el sector bajo estudio de la península del lago Cardiel, con el sitio arqu...
The aim of this paper is to discuss the role of faunal remains in funerary contexts from Southern Patagonia. We will particularly emphasize the information obtained in mortuary contexts from Lake Salitroso (Santa Cruz Province, Argentina). In this area a total of 37 burials of different types, such as chenques (i.e. artificial rock burial mounds),...
The guanaco (Lama guanicoe) is the largest and the most widely distributed ungulate in South America since the
Pleistocene and constituted the main prey for hunter-gatherers in Southern Patagonia (Argentina) in the past. An
isomorphic relationship has been suggested between the mobility of these animals and that of human groups that
inhabited the r...
En el centro-oeste de Santa Cruz (Patagonia, Argentina) se han desarrollado investigaciones arqueológicas desde hace más de 40 años. Desde sus inicios, el equipo de trabajo estableció vínculos con las comunidades de Perito Moreno, Gobernador Gregores y Lago Posadas y se desarrollaron charlas y talleres con distintos actores sociales de estas locali...
RESUMEN Los cazadores-recolectores de Patagonia han utilizado una variedad de artefactos líticos, entre ellos, las hojas y láminas, registradas desde fines del Pleistoceno en diversos sitios de la región. El uso de estas formas base ha sido objeto de estudio desde los inicios de la arqueología patagónica, cuando se consideró que la abundancia de la...

La cuenca del Lago Salitroso (noroeste de Santa Cruz) posee una alta concentración de entierros humanos con cronologías correspondientes al Holoceno tardío. La modalidad funeraria en chenque conforma el grupo más tardío y recurrente de entierros (ca.1.500-300 años AP), siendo frecuentemente estructuras mortuorias múltiples.
Los estudios genéticos...
This work states that hunting guanaco (Lama guanicoe) in plateaus from Southern Patagonia increased progressively during the Late Holocene (ca. 2500 years BP) and entailed effective technologies combined with new demographic configurations and mobility strategies among hunter-gatherer groups (extensification processes and population convergences)....
There is still debate about when and how the peopling process of South America developed, particularly in southern Patagonia. Earliest evidence corresponds to chronologies beginning at circa 11,000 radiocarbon years ago. Regarding the archaeological record, discussions about early peopling often have been related to the existence of a particular ty...
En el centro-oeste de la provincia de Santa Cruz (Argentina) las puntas de proyectil que predominan desde el Holoceno temprano hasta el Holoceno medio se corresponden con una morfología que no presenta pedúnculo. Por tal razón, este diseño apedunculado ha sido considerado como un fósil guía para la asignación cronológica de contextos arqueológicos....
La cuenca del Lago Salitroso (noroeste de Santa Cruz), posee una alta concentración de entierros humanos con cronologías correspondientes al Holoceno tardío. Este rasgo distintivo de la región frente a la dispersión y escasez del mismo en el resto de la Patagonia, conforma un escenario propicio para el estudio de la diversidad genética de los indiv...
Las investigaciones en Lago Salitroso (noroeste de Santa Cruz) han permitido identificar una de las concentraciones de entierros humanos más grande de Patagonia. Su estudio bioarqueológico sistemático ha contribuido a la discusión de diversos aspectos de los comportamientos mortuorios de los grupos que habitaron el área durante el Holoceno tardío....
Estudios paleodemográficos previos han mostrado que el perfil de mortalidad de la muestra osteológica de chenques tardíos (ca. 800-350 años AP) de la cuenca del lago Salitroso (Santa Cruz) es compatible con un perfil atricional característico de las poblaciones cazadoras-recolectoras. Asimismo, se ha sugerido que la población habría experimentado c...
Durante el Holoceno tardío la dinámica poblacional humana en Patagonia estuvo condicionada por factores ambientales, debido a que la tendencia hacia condiciones de mayor aridez afectó sustancialmente las cuencas hídricas y sus ambientes asociados. En particular, para la cuenca del Lago Salitroso (noroeste de la actual provincia de Santa Cruz, Argen...

tardíos (ca. 800-350 AP) del lago Salitroso (SAC) y sus implicaciones para las discusiones vigentes sobre prácticas mortuorias y cuestiones demográficas en el área. Se trata de SAC 1-2, un chenque primario múltiple, compuesto por un adulto femenino y 5
individuos infa...
In this article, two new radiocarbon dates from a late chenque (ca. 800-350 AP) at Lake Salitroso (SAC) are presented. These dates have implications for current discussions concerning mortuary practices and demography in the region. The case discussed is chenque SAC 1-2, a multiple individual, primary burial, containing one female adult and 5 infan...
The main aim of this paper is to evaluate if certain processes that were documented in a specific area of Central-Southern Patagonia during the Late Holocene were also registered in a broader spatial scale. Previous investigations carried out in our study area located in Central-Western Santa Cruz province, Patagonia, have stated that climatic fluc...
El Noroeste de la Provincia de Santa Cruz presenta un registro arqueológico de gran importancia. En particular, en la cuenca del Lago Salitroso se ha recuperado y estudiado una de las colecciones osteológicas más numerosas de poblaciones cazadoras-recolectoras, ubicándose temporalmente en el Holoceno Tardío. En el presente trabajo se exhiben los re...
Archaeozoological studies in Patagonia have tended in the past to focus on evidence provided by rock-shelters. However, a regional perspective, such as the one employed in this paper, allows us to identify trends and patterns during the Late Holocene (last 2,500 years) that could remain in the shadows if a microregional scale alone were used. Clima...
The reconstruction of glacial paleolake formation and evolution allows the understanding of glacier advance and retreat behavior for longer periods of time. New datings obtained from paleolacustrine deposits in the Argentinian Patagonian Andes (Northwestern region of Santa Cruz Province) reveal that glacial lakes formed before the Last Glacial Maxi...
The aim of this work is to use spatial analysis to study relationships between environmental parameters and archaeological sites in the Santa Cruz province (Patagonia, Argentina) and to develop an analysis protocol that could reveal including and excluding factors, useful for the research and the discovery of new archaeological sites on the territo...

LITHIC RESOURCES AVAILABILITY AND MOBILITY DURING LATE HOLOCENE IN THE CENTRAL WEST OF SANTA CRUZ PROVINCE. The characteristics of the regional lithic resources base in central western Santa Cruz present a high frequency, distribution and variety of raw materials of excellent quality for knapping that includes black obsidian as well as basalts, sil...
Hunter-gatherer mobility and spheres of interaction are important characteristics worthy of investigation in Patagonian archaeology. One way to approach these is by studying the distribution of lithic archaeological materials. Siltstone (limolite) artifacts are found along the western strip of southwestern Patagonia, Argentina. Based on geomorpholo...
This paper summarizes and discusses the main results achieved over three decades of research on paleodemographic aspects of Late Holocene hunter-gatherers in Northwestern Santa Cruz (Argentina). Research has been guided by a model of regional settlement that proposes that, as a result of the progressive aridization process recorded in Patagonia dur...
We study the isotopic variability of modern social groups of guanacos (Lama guanicoe) and discuss the implications of these results for the analysis of archaeofaunas from archaeological sites of Patagonia. The aim of this work is to evaluate whether the study of the isotope composition of carbon and nitrogen from collagen (δ13C and δ15N) is a metho...

The role and extent of climate as a cause of the expansion and decline of human cultures is still debatable. It is clear, however, that human–environment interactions are enhanced and interplay more closely in climatically sensitive areas such as around hydrologically closed basins. Lago Cardiel is located at 49° S in the very arid rain shadow east...
The aim of this study was to examine the parasite remains present in rodent coprolites collected from the archaeological site Alero Destacamento Guardaparque (ADG) located in the Perito Moreno National Park (Santa Cruz Province, 47 degrees 57'S 72 degrees 05'W). Forty-eight coprolites were obtained from the layers 7, 6 and 5 of ADG, dated at 6,700...
This work aims to present the carbon and nitrogen stable isotope data for human and environmental samples in order to discuss the dietary patterns of Late Holocene hunter-gatherers from Salitroso Lake (southern Patagonia, Argentina) within the framework of ongoing research oriented to investigate the socio-ecology of these populations. We present d...
Interactions between human societies and the environment that they inhabit have been a controversial topic in archaeology for at least the past fifty years. Currently, modern theoretical approaches take this subject as a key issue in their research agenda. This paper presents a review of the main outcomes of several archaeological and multidiscipli...
This work presents and discusses the carbon isotope data obtained from the analysis of human bone remains from 25 individuals of the locale of Sierra Colorada (Salitroso lake basin), 19 of which have been dated directly by 14C-AMS to between ca. 2750 and 300 cal. BP. This information enables us to examine diet composition through the Late Holocene...
A recent model predicts certain features of human occupation during the Late Holocene in central-south Patagonia (2500-200 yrs BP). In contrast to earlier periods, mobility was more restricted, and a system of relatively stable residential camps and cemetery chenque. Were supported developed in lower eastern steppes. Whereas the higher forest or ec...
