“…Besides the nine sites presented in this work (Figure 2), a total of eight rockshelter and open-air sites have been already studied in the adjacent central-eastern sector of the Tandilia range (Flegenheimer et al, 2006;Prates et al, 2011). As a whole, this diversity of sites demonstrates the functional variability and the types of settlements that characterized early human populations in this region.…”

The Tandilia range is a discontinuous series of hills and valleys located at the central area of the Pampean region (Argentina). The process of human settlement reached in this zone the highest population densities and reoccupation levels of Southern South America, developing under the strongly changing climatic conditions that characterized the Pleistocene-Holocene transition. This paper analyzes the geoarcheological and paleoenvironmental record of the Pleistocene-Holocene transition (c. 9400-10,500 14 C BP) recovered from cave and rockshelter sedimentary successions of the Tandilia range. The analysis of several lines of evidence (stratigraphic, geoarchaeological, archaeological, zooarchaeological, and paleobotanical), suggests that a cold arid to semi-arid climate characterized the late Pleistocene (c. 10,500 BP), and changed abruptly to warmer conditions towards the beginning of the Post-Glacial Period. As a consequence of this climatic amelioration, the populations inhabiting the Tandilia range would have been benefited by a higher availability of resources, which could explain the higher levels of site density and reoccupation found in the area during this period.

“…Although the process of human occupation of the Pampean region began c. 12,100 14 C BP (Politis, et al, 2004;Steele and Politis, 2009;Prates, et al, 2011), most archaeological evidence is found between c. 11,000 and 9600 14 C BP. During this period, a wide variety of pampean subenvironments became fully occupied.…”

“…In Uruguay, Paleoamerican occupation is registered since at least ca. 12,000 BP (for early dates in the Southern Cone, see Beltrão 2000; Bueno et al 2013;Méndez Melgar 2013;Prates et al 2013;Suárez 2014;Suárez in press) and it is characterised by mobile hunter-gatherers exploring and colonising the plains, rockshelters and lowlands along the major rivers (e.g., Uruguay River, Negro River) that connect the interior of the continent (southern Brazil, northeastern Argentina) to the Atlantic coast (López Mazz 2013; Suárez 2015; Suárez in press). The growing focus on the archaeology of the 'First Americans' since the end of the last century brought new vigor to procurement studies in Uruguay.…”

Abstract:Being a territory with several minerals and rocks suitable for knapping and grinding, Uruguay offered a lithic-rich environment for past indigenous cultures in the Southern Cone of South America. In this paper, a history of lithic procurement studies in Uruguay is presented. Three main periods are discriminated, paying attention to authors' theoretical and methodological contributions to the field. Firstly, a period with general mention to raw materials utilised by indigenous groups, including those historically known, is recognised at least since the last decades of the nineteenth century. Secondly, a period involving description of lithic resources available at a national scale as well as the first detailed observations of lithic sources and possible means of procurement can be distinguished between the 1950s and the mid-1980s. Lastly, beginning with salvage archaeology in the eastern region, the current period of research (i.e. the last thirty years) is characterised by contextualising lithic procurement within issues of lithic technological organisation and settlement patterns of indigenous groups. The current period of studies has involved two different approaches: 1) technological analysis of lithic artefacts and comparison of raw material with previously-published geological data; 2) utilisation of field survey data that locate and map lithic resources, and characterisation of visual (macroscopic, microscopic, or both macroscopic and microscopic) and geochemical components of these resources. Within the latter, studies can be further arranged according to the main temporal framework used to contextualise research problems. On the one hand, questions involving lithic procurement of early hunter-gatherers (who arrived ca. 12,000 BP) since the end of the 1990s have included surveys of potential and utilised sources, the first thin-section-based petrographic studies and the distinction of different local, regional and long-distance procurement strategies. On the other hand, cultural changes since the Middle Holocene have framed lithic source survey studies to answer questions of resource accessibility for coastal groups during sea level changes, as well as for other now-diverse groups such as the lowland moundbuilders. Finally, considerations for future research are made by reconsidering recent developments alongside the history of lithic procurement studies in Uruguay.

“…En Patagonia, este tipo de puntas de proyectil han sido registradas en las localidades de Cueva de Fell, Pali Aike (Bird, 1993), Cueva del Medio (Nami, 1985-6), Tres Arroyos 1 (Jackson, 2002;Massone, 2004), Piedra Museo (Miotti, 1995), Los Dos Amigos Oeste (Miotti et al, 2010), y de forma aislada en Estancia Pali Aike (Nami, 1994), Cerro Iturbe (Jackson, 2004) y en colecciones (Bahamondes & Jackson, 2006). Si bien la cronología asociada a este tipo de cabezales en Patagonia requiere aún precisarse, un recuento de los fechados más confiables permite sugerir su ocurrencia en el intervalo entre 11.100 a 10.400 años 14 C AP (~12.980 a 12.270 años cal AP) (Nami & Nakamura, 1995;Prates et al, 2013), sin que esto permita descartar eventuales evidencias fuera de este rango. Por ello es posible considerarlas como un apropiado marcador temporal para construir hipótesis respecto a los espacios disponibles para los primeros pobladores de la región (Miotti et al, 2010(Miotti et al, , 2012.…”
