    We present the results of the excavations and analyses of the diverse and exceptional archaeological assemblage of Taguatagua 3, a new late Pleistocene site located in the ancient Tagua Tagua lake in Central Chile (34 degrees S). The anthropogenic context is constrained in a coherently dated stratigraphic deposit which adds new information about the mobility, subsistence strategies, and settlement of the early hunter-gatherers of southern South America. The age model constructed, as well as radiocarbon dates obtained directly from a combustion structure, indicate that the human occupation occurred over a brief time span around 12,440-12,550 cal yr BP. Considering taphonomic, geoarchaeological, lithic, archaeobotanical, and zooarchaeological evidence, as well as the spatial distribution combined with ethnographic data, we interpret Taguatagua 3 as a logistic and temporary camp associated mainly with gomphothere hunting and butchering. Nevertheless, several other activities were carried out here as well, such as hide and/or bone preparation, small vertebrate and plant processing and consumption, and red ochre grinding. Botanical and eggshell remains suggest that the anthropic occupation occurred during the dry season. Considering the contemporaneous sites recorded in the basin, we conclude that the ancient Tagua Tagua lake was a key location along the region's early hunter-gatherer mobility circuits. In this context, it acted as a recurrent hunting/scavenging place during the Late Pleistocene due to its abundant, diverse, and predictable resources.

    The ways of fish beyond the sea: fish circulation and consumption in the Atacama desert, northern Chile, during the Formative period (500 cal BC-700 cal AD.)
    (2019) Ballester, Benjamin; Calas, Elisa; Labarca, Rafael; Pestle, William; Gallardo, Francisco; Castillo, Claudia; Pimentel, Gonzalo; Oyarzo, Cristobal
    Along the Atacama Desert coast, fish has always been a staple food and by the Formative period (500 cal B.C.-700 cal A.D.) it had become a product in high demand by the inhabitants of the inland valleys, oases and ravines of the desert. In this paper we explore the technologies used in coastal fishing activities, the diverse species caught, and fish processing and preserving techniques. We further examine the circulation routes of the product through the desert and associated strategies, the agents involved in transporting it and consumption levels in inland villages. Our study employs a multivariate analysis that includes evidence from zooarchaeology, stable isotope analysis of deceased individuals, and the composition of human coprolites, all of which were recovered from domestic waste, funerary contexts, and rest stops associated with the circulation routes running between the coast and the inland desert regions. Our results suggest that in this ancient social context, food was not only used to quell hunger, but through its associated economic cycles of production, circulation and consumption, was part of a complex and extended web of social relations. Within that network, food functioned as material culture, and as such enabled social distinctions to emerge within local groups and cultural negotiations to be conducted among different localities. Fish circulation and consumption played an active role in the reproduction of a social structure characterized by dose and firm ties between marine hunter-fisher-gatherers and agropastoral communities, despite their long distance from each other.
