“…A high diversity of lithic tools was found, including side scrapers, end-scrapers, knives, multipurpose tools, triangular projectile points, etc. ( Messineo et al., 2019 ). In addition, a standardize bone technology was also identified in LLP and centered in the production of beveled tools and blunted points made on guanaco tibiae ( Messineo et al, 2019 ).…”

“…In order to address these potential issues and to better understand the population history of the Argentinian Pampas and its implications in the peopling of the SCSA, we analyzed whole mitogenomes from well-dated human skeletal remains from three Early to Late Holocene archaeological sites in the Argentinian Pampas: Arroyo Seco 2 (AS2) ( Politis et al, 2014 ; Politis et al., 2016 ), Laguna de los Pampas (LLP) ( Messineo et al., 2018 ; Messineo et al., 2019 ), and Laguna Chica (LCH) ( Scheifler et al., 2017 ; Messineo et al., 2019 ) ( Figures 1 and S1–S3 ; supplemental information text). We further employed a tip-calibration approach to determine the divergence ages and to better understand the evolutionary history of the SCSA-specific mitochondrial clades D1g and D1j, as well as the Pan-American minor founding lineage D4h3a that has its highest frequencies in Patagonia and Tierra del Fuego.…”

Summary The Southern Cone of South America (SCSA) is a key region for investigations about the peopling of the Americas. However, little is known about the eastern sector, the Argentinian Pampas. We analyzed 18 mitochondrial genomes—7 of which are novel—from human skeletal remains from 3 Early to Late Holocene archaeological sites. The Pampas present a distinctive genetic makeup compared to other Middle to Late Holocene pre-Columbian SCSA populations. We also report the earliest individuals carrying SCSA-specific mitochondrial haplogroups D1j and D1g from Early and Middle Holocene, respectively. Using these deep calibration time points in Bayesian phylogenetic reconstructions, we suggest that the first settlers of the Pampas were part of a single and rapid dispersal ∼15,600 years ago. Finally, we propose that present-day genetic differences between the Pampas and the rest of the SCSA are due to founder effects, genetic drift, and a partial population replacement ∼9,000 years ago.

“…En la actualidad los herbívoros nativos grandes, como el guanaco ( Lama guanicoe , 80–120 kg) y el venado de las pampas ( Ozotoceros bezoarticus , 30–40 kg), se encuentran ausentes en el área de estudio, pero los huesos de estas especies son abundantes en los sitios arqueológicos que poseen cronologías del Holoceno medio y tardío (Scheifler 2019). En el área no se registran fuentes de rocas de ningún tipo y la distancia en que se encuentran las mismas supera los 200 km (Messineo, Pal et al 2019).…”

Huencú Nazar es un sitio arqueológico a cielo abierto localizado en el Sistema Lagunar Hinojo-Las Tunas (región pampeana, Argentina) que fue ocupado durante el Holoceno tardío (ca. 3000 aP). En un área de 5.000 m2 se distribuyen 22 fogones, escondrijos de roca y concentraciones de rocas granitoides. En uno de los sectores excavados se registraron fogones en cubeta y el uso de huesos de Lama guanicoe (Artiodactyla, Camelidae) como combustible. El uso de combustible óseo permitió solucionar el problema de los residuos molestos para la comodidad de las personas ubicadas alrededor de los fogones. En torno a las estructuras de combustión se depositaron materiales relacionados con la subsistencia y la tecnología.

“…Archaeologists often integrate the relative quality (asserted or demonstrated) of knappable toolstone into discussions of forager raw material acquisition, mobility, trade, and tool type (e.g., Andrefsky, 1994a, 1994b; Aubry et al, 2012; Bamforth, 1986; Buchanan et al, 2014; Dibble, 1995; Doelman et al, 2001; Kuhn, 1991; Messineo et al, 2019; Parry & Kelly, 1987; Rosencrance & Hirshman, 2020; Selden et al, 2021; Wilkins, 2017; see also citations throughout this manuscript). In some cases, prehistoric people directly transported, or traded for, higher‐quality rocks from far “exotic” distances, while lower‐quality rocks were acquired “locally” (e.g., Bobak & Połtowicz‐Bobak, 2018; Horowitz, 2018a).…”

Knapping quality of local versus exotic Upper Mercer chert (Ohio, USA) during the Holocene

Stone that fractured conchoidally was an important resource for prehistoric huntergatherers. In recent years, archaeologists have come to realize that rather than defining stone "quality" simply and implicitly as "high" or "low," a stone's quality can be best defined in several different explicit and often quantitative ways involving production, function, or social benefits. Here, we examine the stone quality-defined as "fracture predictability"-of Upper Mercer chert when it is locally versus nonlocally acquired by prehistoric people in Ohio, USA. By quantitatively assessing silicon dioxide (SiO 2 ) content and loss on ignition, we compared stone tools from a site at the Upper Mercer outcrop (n = 42) to those found at archaeological sites over 100 km north of it (n = 126). Our results showed that the former on average were of significantly higher quality than the latter. We conclude with a consideration of factors that could cause this difference in quality, suggesting that the lower quality of Upper Mercer chert in northern Ohio might be explained by northern people's decreased familiarity with it during the Archaic period and by their decreased access to it during the Woodland and Late Precontact periods.
