Bioarchaeological research of bone growth patterns provides information on the health status and disease of past populations. Recent studies have pointed out the potential of metric analysis of nonadult vertebrae as indicators of stress during different stages of ontogeny, highlighting that most vertebral measurements present low sexual dimorphism, a stable and known pattern of growth and give useful information even in incomplete spines. The aims of this paper are first, to construct a vertebral growth profile for nonadults of a skeletal series of Patagonian Late Holocene hunter‐gatherers from Salitroso Lake (SAC); second, to compare it to the ones obtained in other archaeological and modern populations with different stress experiences; and third, building on this, to assess whether individuals with evidence of stress experienced in early development demonstrate different patterns in vertebral growth than those without. Two spinal dimensions are used: vertebral body height (VBH) and transverse diameter of the neural canal (TDNC) in a sample of 23 nonadult skeletons with ages previously estimated from dental and bone indicators. The vertebral dimensions of 20 adults between 18 and 35 years of age were also measured as reference information. Results show that the growth of the VBH is steady over the years and reaches adulthood size by approximately 16 years of age whereas TDNC dimensions do not experience marked fluctuations in size throughout life and adult dimensions are reached at approximately 4 years of age as expected. The vertebral growth pattern observed in SAC is similar to that obtained in other archaeological samples from very different settings but experiencing relatively high nutritional or pathological stress in early stages of life. However, it is markedly different, and systematically smaller, to the 20th century sample pattern, probably responding to a secular trend in the modern population with a more stable access to resources and medical treatment. Finally, SAC individuals with systemic stress markers do not tend to exhibit smaller vertebral dimensions than those without them. [ABSTRACT FROM AUTHOR]

This paper presents the results of a study of firewood use and management by human groups in the Ongamira valley, Córdoba, Argentina (dated between c. 5700-950 BP). In order to understand firewood gathering practices at different periods in the Late Holocene, samples from 63 combustion events recorded in 9 rockshelters were analysed. From the anthracological analysis (14,976 fragments) 19 woody taxa, and 4 botanically indeterminate taxa, were identified belonging to Chaco Serrano forest vegetation. The identification of abundant small flat fireplaces suggests short-lived activities repeated over time. A detailed analysis of the samples (types of fire pits, alterations during combustion and taphonomic processes) permits inferring firewood gathering in the local vegetation around the sites, as well as some taxa belonging to different environmental settings. Archaeological evidence indicates that groups were mobile, with the establishment of a network of places in the landscape where different activities were carried out (tool production, food consumption and pottery manufacture) with fire making as a central activity. People in the past constantly used different places in the valley, focusing many of their activities in rockshelters. [ABSTRACT FROM AUTHOR]

The aim of this paper is to discuss conceptual and methodological issues related with the archaeological study of lithic landscapes and exemplify the approach with a case study (artifact distribution data from east-central Argentina). A lithic landscape-understood as the co-occurrence, in a given geographic space, of different structural units each one composed by a raw material source and the complete set of unmodified and human-modified pieces of rock extracted from that source and then transported, used, and discarded across the landscape ( i.e., a scatter area)-can be modeled using kriging, a geostatistical interpolation tool useful for integrating scattered information into coherent spatial models. The case study allows for the examination and discussion of, on one hand, the relationships between the type and location of the sources and the size and shape of the respective scatter areas and, on the other, the reciprocal relationships between different raw materials and sources. It is concluded that a proper description of the spatial structure of a lithic landscape is the needed baseline from which to evaluate different explanatory models. Such models should take into account different sets of initial conditions and generative mechanisms, in order to cope with the pervasive problem of equifinality. [ABSTRACT FROM AUTHOR]

This paper shows the preliminary results of the zooarchaeological analysis of Dupuy Rockshelter (La Toma, San Luis Province, Argentina). This rock shelter has evidence of Late Holocene (Last Millennium) human occupation dating from 340 ± 40 BP. Some species, including Lama guanicoe and Ozotoceros bezoarticus , were exploited and their bones were used as raw material to make instruments. The zooarchaeological analysis is complemented by geological and phytoarchaological evidence which indicates a humid environment during the Holocene and a mixed diet that included vegetables.

This paper presents the analysis of the ichtyoarchaeological record from Los Bananos site (Goya, Corrientes, Argentine). The aim of this study is to render a first evaluation to the role played by fish in subsistence during subsequent occupations of the site. The site is located in the alluvial plain of Middle Paraná River, beside Paraná Miní creek, and it has provided new information about pottery and lithic technology, subsistence, chronology ( 14 C), site formation processes, etc. Bones from Los Bananos have been divided into three assemblages (LB1, LB2 and LB3), according to associated cultural materials. The pre-Hispanic populations that occupied this area by the end of the Late Holocene based their subsistence in hunting, gathering and fishing. Also, the makers of a distinctive ceramic ware associated with LB1 assemblage (related to Goya-Malabrigo entity - lato sensu -), relied on small-scale horticulture. Preceding materials of the other sets (LB2 and LB3) do not present necessary characteristics for cultural association as shown in LB1. The assemblages will be discussed in sequence of their deposition; and compared with results from other related sites. The results of zooarchaeological and taphonomic analysis of the faunal remains suggest that fish was an important resource in LB1. While from LB3 analysis, we will see that fish constituted a complementary resource in the diet. Thus, we can infer that, the role of animals in the diet of the site's prehistoric inhabitants changed during the time deposits were laid. [ABSTRACT FROM AUTHOR]

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 during the Late Holocene, human groups would have reduced their residential mobility and concentrated their settlements in low altitude basins with water availability, such as Lake Cardiel and Lake Salitroso. Paleodemographic questions derived from the model relate to population regional continuity and dynamics and were tested using several lines of research at regional and local scales. The assessment of the chronological information and temporal trends of the archaeological record at the regional level allowed for a coarse grain paleodemographic approach, and acted as a mean to support hypotheses related to changes in mobility and land use strategies. Building on this, several lines of bioarchaeological evidence were used to address paleodemographic aspects of the model, including temporal, distributional, and compositional studies of the mortuary record, isotopic, morphometric and DNA analyses and the sex and age structure of the skeletal samples recovered in Lake Salitroso basin. Results point to a biological and cultural population continuity in the region during the Late Holocene. Also, a reduction in residential mobility would have favored a slight population growth of Lake Salitroso populations during the last millennium. [ABSTRACT FROM AUTHOR]

Zooarchaeologists have relied upon various approaches to study the impacts of harvest pressure and environmental change on ungulate populations, such as analysis of prey mortality patterns and morphometrics. Analysis of ancient DNA from ungulate bones and bone fragments from archaeological sites provides an additional means for studying prey population dynamics related to environmental change and human ecology over time. In this paper, we study the population history of the largest game animal in northwest Patagonia, the guanaco (Lama guanicoe). Our study relies on the use of Bayesian Skyline Plots to determine shifts in estimated guanaco population size based on analysis of ancient mitochondrial DNA. Our results indicate that hunting by humans in addition to increases in aridity during the late Holocene led to a decline in the guanaco population in the region, which is in contrast to the harvest and environmental history in other parts of Patagonia (south of our study area). Using a weight of evidence approach that includes proxies of environmental change, human population dynamics, exploitation of guanacos, and estimates of guanaco population size, we argue that the late Holocene shift in guanaco population size was a driving factor in subsistence and settlement change related to resource intensification during the late Holocene in northwest Patagonia. • Demographic reconstruction of guanaco population dynamics during the Holocene. •Estimated population size is based on ancient DNA analysis through Next Generation Sequencing. •There are key changes in guanaco population size during the late Holocene. •Late Holocene guanaco population relates to increased hunting pressure in northwest Patagonia.
