“…The assemblages are interpreted as distinct events of short‐term hunter‐gatherer human occupation, in which different activities took place, mostly associated with animal processing and consumption, stone tool making and probable plant processing. Considering that the Agua de Pérez locality is next to a siliceous raw material source (Salgán et al., ) and that the number of flakes and tools recovered from the site is relatively low, it is likely that the main activity at these sites was associated with food procurement.…”

Archaeological site formation processes in northwestern Patagonia, Mendoza Province, Argentina

The Cañadón Amarillo area in northwestern Patagonia (Mendoza Province, Argentina) presents a rich archaeological record contained within thick successions of fine‐grained deposits with well‐constrained chronological and stratigraphic resolution. Geomorphological, sedimentological, and archaeological analysis of three archaeological localities, constrained by radiocarbon ages, was conducted to reconstruct site formation processes and depositional variability in an exposed, dryland setting. The archaeological sites are located in the Cañadón Amarillo area between the southern margin of the volcanic Payunia Plateau and the Colorado River, in an area of ephemeral streams and eolian sand sheets. The archaeological remains are preferentially contained in fine to very fine sand to silty sand deposits associated with the ephemeral streams. Low‐energy fluvial deposition related to overbank flows, and eolian aggradation associated with coppice dunes, sand shadows, and unrippled and partially vegetated mantles have favored preservation of in situ archaeological materials. Our investigations provide insight into site formation processes in exposed settings within the semiarid parts of northwestern Patagonia and extend the local record of human occupation to ∼7300 14C yr B.P.

“…These preliminary trends show that eggshells can be used to explore the distribution of past human occupation ranges and/or their exchange systems. Recently, researchers have demonstrated the meaning of non‐local items in human strategies in northern Patagonia (Neme & Gil, ; Salgán et al ., ), but the role of eggshells has not been previously considered.…”

Rheidae eggshells are abundant in the archaeological record of west central Argentina. Eggs were more important in human diet than the bird meat itself, as with many other Ratite species around the world. Currently, two species inhabit the south and central areas of Argentina and Chile (Rhea pennata and Rhea americana), with different geographical distributions and diet but with similar behaviour. In this paper, we use δ13C and δ18O isotopes from Rheidae eggshells to explore the ratite diet, its spatial differences in the archaeological record, and their importance in human diet, and as a way to approach human mobility in hunter‐gatherer societies from west central Argentina. There was a significant correlation between both δ13C and δ18O isotope data and the Rheidae species' distribution in the landscape, showing differences in their past diet and territoriality. Additionally, the unexpected δ13C and δ18O isotope values in the Altoandina Desert area suggest human transport of the Rheidae eggs to these locations. The isotopic data from the eggshells need to be incorporated into the ecological history of the region in order to understand past human diet and mobility. Copyright © 2013 John Wiley & Sons, Ltd.

“…For example, sources and subsources have been identified, reassigned and sometimes redefined, while others remain unknown. There were discoveries of new ones (Varvarco), and knowledge about the dispersal ranges of some sources has advanced (Barberena et al 2011;Cortegoso et al 2012;Giesso et al 2011;Salgán et al 2012;2015;Stern et al 2012). All of this allows us to rethink our own discussions and generate new ideas about the procurement and circulation of obsidian in the province of La Pampa.…”

“…Except for the aforementioned cases, whose availability in a secondary way could imply a direct supply, it is considered that the acquisition had to take place within the framework of the exchange networks that were developed in the Norpatagonian bioceanic corridor from the end of the Middle Holocene. In addition to the wide distance between the sources and the place where the samples were recovered, it must be added that the characteristics of the analysed artefacts correspond to those expected for those generated in rocks obtained through indirect access (Salgán et al 2012). In this sense, most of the artefacts correspond to small and internal waste associated with the last stages of the production system, or conservated instruments.…”

The goal of this study is to report the progress regarding the procurement and circulation of obsidian by hunter-gatherer populations during the Late Holocene in the province of La Pampa, Argentina. A total of 25 samples were analyzed in two stages; in the first stage neutron activation analysis (INAA) was used, while X-ray fluorescence (XRF) was employed in the second stage. This work adds nine archaeological samples from new sites and one from the Lihué Calel obsidian source. The results allow us to take into account the sourcing of the obsidian which was found in archeological sites of four areas of study located in the south and east of the province. Both, the results generated in this new stage, and those previously obtained are integrated and discussed in relation to the information produced by other researchers from the region, which are consistent with the existing ones for La Pampa. They indicate that the obsidian recovered was procured from sources located in the Argentinian and Chilean Andes, as well as the pre-cordillera in the provinces of Neuquén and Mendoza. New data expands the spatial perspective of our interpretations to four new research areas: Curacó basin, Lihué Calel hills, Valles Transversales (Transversal Valleys) and Bajos sin Salida (Endorheic low areas).
