En este trabajo se presenta el estudio de los sitios con arte rupestre del faldeo oriental de la Sierra de Velasco y occidental de la Sierra de La Punta (norte de la provincia de La Rioja, Argentina). Los objetivos son definir la diversidad de representaciones a nivel local, evaluar la circulación de información a escala regional y examinar su rol en la conformación de paisajes sociales, durante los últimos 2.000 años. Para ello se realiza un análisis de los repertorios iconográficos y de los vínculos entre imágenes y contextos de emplazamiento. Los resultados sugieren que los sitios rupestres distribuidos en altitudes contrastantes implicaron diferentes prácticas sociales. Los emplazamientos pedemontanos, integrados a los espacios residenciales y productivos, se habrían conformado en torno a prácticas domésticas y simbólicas recurrentes, mientras que aquellos situados en las serranías de La Punta estarían vinculados con el uso de vías naturales de circulación. Esta segregación espacial involucra, a su vez, distintas temporalidades para la producción y el consumo de arte rupestre.

Even though lithics in the Maya region have traditionally been relegated to appendices and tool-type lists, much has been done to move beyond this descriptive approach in the last decade. In this article we highlight general themes of lithic studies in the Maya region since 2011, including economic production and exchange, the role of lithics in ritual practice, and the use of previously understudied raw materials and lithic forms, such as ground stone. Employing a temporal scope that encompasses the Maya and their preceramic predecessors, we explore gendered patterns of research within lithic studies from a feminist perspective and discuss the impacts that gender disparities have on academic thought.

This article presents the first findings of a topographic survey plotting the location of archaeological material and of a technological study of the lithic industry at the SC-CHA-030 open-air archaeological site along the Pesqueiro riverbank, located in the upper course of the Uruguay River Basin in southwestern Brazil. We analyzed raw material selection and the production of shaped/façonnage tools (unifacial, bifacial, and trihedral) associated with the production (debitage) of cortical and semi-cortical flakes that were then transformed into tools by simple retouch. From the geoarchaeological point of view, the spatial distribution pattern of the material is meaningful in the context of the geomorphic transition between foothills and alluvial plain. Our study of technological behavior and the formation of archaeological sites finds that raw material and shaped pebble tools are a crucial aspect of the industries on the Paraná Basaltic Plateau of southern Brazil.

Biophysical conditions played a fundamental role in early human colonization of insular territories, particularly in food-producing societies dealing with limited resources and the challenges of maintaining a sustainable carrying capacity. Studies on past human colonization of small oceanic islands thus offer insights into economic plasticity, ecological impacts, and adaptation of early food-producing groups. On the coast of southern Chile, early evidence is dated to 950 cal BP of island colonization by coastal populations with mainland subsistence systems based on the exploitation of marine resources, along with gathering, managing, and cultivating plants and hunting terrestrial animals. Strikingly, the extent to which these mixed economies contributed to insular colonization efforts is largely unknown. Here we used organic residue analysis of ceramic artifacts to shed light on the subsistence of populations on Mocha Island in southern Chile. We extracted and analyzed lipids from 51 pottery sherds associated with the El Vergel cultural complex that flourished in southern Chile between 950 and 400 cal BP. Chemical and stable isotope analysis of the extracts identified a range of food products, including C3 and C4 plants and marine organisms. The results reveal the central role of mixed subsistence systems in fueling the colonization of Mocha Island.

During the Middle Horizon (AD 600–1000), obsidian was transported in greater quantities and distances than ever before identified in the Andes, in part by the expansionary Wari state. Two of the three major obsidian sources used in the south-central Andes are located in the modern department of Arequipa, Peru. Arequipa was a region of intense Wari influence and intrusive presence; however, little is known about regional obsidian use. Portable X-ray fluorescence (pXRF) and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) were used to analyze 383 obsidian artifacts recovered from 10 archaeological sites in Arequipa. Results highlight diachronic and spatial patterning related to obsidian procurement strategies, state versus bottom-up exchange networks, and local participation within the Wari realm. A wide variety of geological obsidian sources, including nonlocal obsidians originating from Wari's Ayacucho heartland, were used. By the late Middle Horizon, the Wari had consolidated regional resources with the sole use of Alca-1 and Alca-4 bedrock obsidians, the largest-sized and highest-quality sources in the area. We assess related models of obsidian procurement and exchange related to state political economy, long-distance caravan activity, and the role of local ceremonial/waystation centers that facilitated the flow of ideas, goods, and people across Arequipa.

La organización social de las colonias españolas en América se caracterizó por la desigualdad, configurando estilos de vida disímiles dependiendo de la casta y estamento de pertenencia. Las investigaciones desarrolladas desde una perspectiva paleopatológica en la ciudad colonial de Mendoza (siglos dieciséis al diecinueve), ubicada en el centro-oeste del actual territorio argentino, permitió identificar estados de salud diferenciados en individuos inhumados en cementerios según su procedencia espacial (interior/exterior de los templos). El objetivo de este trabajo es evaluar la distribución de la enfermedad degenerativa articular (EDA) entre grupos de distinta procedencia socioeconómica, inhumados en cinco cementerios católicos coloniales del sitio Área Fundacional de Mendoza. Se relevaron superficies articulares apendiculares de 66 adultos de ambos sexos. No se registraron diferencias estadísticamente significativas entre individuos de diferentes sectores de inhumación, pero sí niveles de estrés mecánico-funcional diferenciados entre sexos según su procedencia social. Se discute la influencia del sexo, la edad y el tamaño corporal en las tendencias identificadas, siendo este último la variable que mayor influencia presentó. Los patrones de uso del cuerpo son interpretados en función del contexto histórico, el sexo y el estatus social del difunto y su familia.

This article examines a new dataset of radiocarbon dates that provides insights into the progressive installation of Inca infrastructure in the Copiapo Valley, situated at the southern edge of the Atacama Desert in northern Chile. It shows that the Inca imperial expansion in this region was not a linear process and was likely shaped by local negotiations and conflicts. The findings describe three main stages of Inca expansion. The first is the construction of the North–South Inca Road and the establishment of high-altitude mountain shrines. The next stage consisted of a physical intervention in a local village located in the upper valley, including the construction of administrative buildings and public spaces. The last stage involved indirect intervention in local villages, characterized by the presence of isolated administrative buildings that were potentially used for diplomacy and negotiation. I argue that the Inca imperial expansion, characterized by evolving strategies across regions and time periods, not only demonstrates the state's capacity for learning but also suggests the pivotal role of local actors in positions of power who wielded agency to shape these developments.
