The quantity of archaeological data for the fortified hilltop settlements of the Late Intermediate period on the Andean altiplano, called pucaras, varies greatly. Some areas, such as the territory of the Colla Aymara chieftaincy east of Lake Titicaca, are well documented thanks to recent and exhaustive research. Other areas, such as the territories of the Lupacas and the Pacajes, are much less documented. From comparative spatial analyses of satellite images from these two territories, we obtained new data on pucaras, whose characteristics seem to differ from those proposed in the archaeological literature. Through a combination of fieldwork and spatial analysis of 295 pucaras, we identified 252 unpublished sites and propose a new typology comprising four categories. Based on ethnohistoric data and the results of the architectural and geographical analyses, we discuss the possible motivations for building so many pucaras; we suggest that some reasons are of a symbolic nature.

Se presentan los resultados del análisis tecnológico, morfológico y estilístico de una muestra cerámica hallada en estratigrafía en una estructura del sitio Corral Grande 1, asignada al período Formativo regional (2400-1100 años aP), en Antofagasta de la Sierra (provincia de Catamarca, Argentina), Andes meridionales. El objetivo del estudio fue caracterizar distintos aspectos de la cerámica para explorar las potenciales diferencias funcionales de las vasijas en el marco de las actividades agropastoriles desarrolladas en el sitio, los patrones de movilidad y el uso del espacio en la región. Los análisis permitieron identificar una alta variabilidad de estilos tecnológicos en el total del conjunto, e inferir que las vasijas pudieron elaborarse para funciones de almacenaje de productos agrícolas, de cocción y servicio de alimentos. Los tiestos más pequeños y livianos pudieron transportarse en el marco de actividades de pastoreo y caza de camélidos. Las comparaciones a nivel regional evidenciaron similitudes tecnológicas y estilísticas con la cerámica de otros asentamientos, y características decorativas que indican la integración del sitio a escala regional e interregional.

This article examines Middle and Late Preclassic period ritual activity and caches discovered in the Central E Group complex at the ancient Maya site of Cival, which is located in northeastern Peten, Guatemala. It focuses on a series of excavations conducted in 2013 and 2014 at Structure 9, the E Group's western radial pyramid and uses theories of social memory and sacred place to provide insight into the recently discovered caches, termination rituals, and the deliberate destruction of architectural features found there. It also draws on previous ritual activity conducted in the Central E Group plaza and the site's broader history to obtain a more comprehensive understanding of the role of this complex as a sacred place and hub of memory at Cival for more than 1,000 years.

We present macrobotanical, starch, and phytolith data from artifacts and sediments from Middle Formative La Blanca (1000–600 cal BC) and Late Formative El Ujuxte (600 cal BC–cal AD 115 ) in the Soconusco region in Guatemala. Potential economic plants identified included palm (cf. Arecaceae), two varieties of maize (Zea mays), guava (Psidium guajava), bean (Phaseolus), chili peppers (Capsicum), squash (Cucurbitaceae), custard apple (Annonaceae), coco plum (Chrysobalanaceae), lerén (Calathea), arrowroot (Maranta), and bird-of-paradise (Heliconia). The results suggest that control of food production and consumption was critical for the transition from complex chiefdoms during the Middle Formative to the archaic state in the Late Formative. The arrival of a more productive South American variety of maize at El Ujuxte (about 2549 BP) allowed elites to exploit an already existing broad-based economic system and to use the maize-based religious system to increase control over maize agricultural practices and maintain power through ideology and disciplinary power. These data suggest that the arrival of fully domesticated South American maize likely influenced the overall development of Mesoamerican state-level societies.

En este artículo se propone un significado para las ofrendas de estatuillas en miniatura de seres humanos y camélidos en ritos incaicos, entre ellos la qhapaq hucha o capacocha, ceremonia principal de veneración a las huacas que incluía sacrificio humano. La investigación moderna ha buscado una explicación satisfactoria respecto de este rito, así como de la función de dichas estatuillas, apoyándose básicamente en información documental. Actualmente, se dispone de información de primera mano proveniente de hallazgos arqueológicos de diferentes cumbres de los Andes. En este trabajo se entrecruzan los datos históricos con los arqueológicos relativos a vestimenta e insignias de la nobleza inca, para proponer que dichas estatuillas simbolizaron a la pareja fundadora del linaje, Mama Ocllo y Manco Capac, en el acto mismo del surgimiento desde la pacarina del cerro Tambotoco, y que representaron por extensión, a los descendientes de tales progenitores. De esta manera, con las estatuillas se habría preservado la memoria de este pasaje crucial del mito de origen de la etnia inca, recordando a la pareja primigenia como creadora del orden social existente, y legitimando a la vez, el origen divino del poder de la élite gobernante.

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.

Este estudio contribuye al entendimiento de la interrelación entre cambio ambiental, modificaciones en las estrategias de subsistencia y movilidad de grupos cazadores-recolectores, y la incorporación de nuevas tecnologías de captura y procesamiento de recursos durante el Holoceno tardío en el centro-oeste de Santa Cruz, Patagonia meridional, Argentina. Se presentan valores inéditos de δ13C sobre apatita y valores de δ15N y δ13C sobre colágeno de 42 individuos recuperados en estructuras de entierros con diferentes cronologías. Se utilizó el concepto de nicho isotópico para entender las continuidades y/o cambios de la dieta cazadora-recolectora. Se evaluó si hubo variaciones temporales y sexuales entre los nichos isotópicos de los individuos con patrones diferentes de organización social y económica en momentos previos y posteriores a los 900 años aP. Los resultados indican cambios en la dieta en los últimos 1.000 años, lo que se plasmó en valores más bajos en δ13Capa de los individuos enterrados en los chenques tardíos y, en particular, en las mujeres. De esta manera, la información paleodietaria apoya la hipótesis de modificaciones en el nicho isotópico a través del tiempo.

In the area along the southern Gulf Coast in Mexico, a large number of previously unrecorded archaeological sites have recently been detected with the aid of lidar data, which also allowed us to determine the orientations of hundreds of structures and architectural assemblages, including many standardized complexes dated to the Early-to-Middle Formative transition. As revealed by our analyses, most orientations were based on astronomical and calendrical principles, occasionally combined with certain concepts of sacred geography. While the results of these analyses were presented in a recently published article, here we explore the potential of alignment data for addressing other questions of archaeological relevance. The distribution of particular building types and regional variations in alignment patterns in the study area suggest the existence of two somehow different cultural spheres, loosely corresponding to the areas conventionally called the Gulf Olmec region and the western Maya Lowlands. Examining pertinent evidence, we argue that it was in this area where some of the most prominent orientation groups materialized in later Mesoamerican architecture originated. We also attempt to reconstruct the paths of their diffusion, which are expected to contribute to understanding the dynamics of long-distance cultural interaction in Mesoamerica.

Se presentan los primeros resultados del análisis de pieles procesadas recuperadas en el sitio Puerto Tranquilo 1, ubicado en el extremo norte de la Isla Victoria, en el Parque Nacional Nahuel Huapi, Provincia de Neuquén, Argentina. El material estudiado proviene de un nivel tardío, por encima de un fogón fechado en 640 ± 60 años aP (1288–1431 cal dC). El conjunto incluye tanto fragmentos de piel con pelo como depilados, con costuras de tendón y pelo, pintados y con reparaciones. Se aplicó una metodología específica para el análisis de las pieles y las fibras, con una descripción técnico-morfológica detallada a partir del análisis macro- y microscópico (SEM/óptico). Las características de la médula y de la cutícula de las fibras permitieron la identificación de Lama guanicoe y Mustelidae (cf. Galictis). Se aplicaron estrategias analíticas y metodológicas novedosas y se generaron datos acerca de las diferentes dimensiones del uso humano de los recursos faunísticos y de la producción de tecnologías en el área boscoso-lacustre norpatagónica. La comparación con otras evidencias arqueológicas, etnográficas y etnohistóricas permitió reconocer rasgos tecnológicos recurrentes en la preparación de las pieles y en la manufactura de artefactos, como parte del proceso productivo del cuero en Norpatagonia.

For many years, the existence of ancient human settlements in the Amazon was deemed impossible, particularly those as old as 12,000 BP as found in Pedra Pintada Cave in Monte Alegre, in the state of Pará, by Anna Roosevelt and colleagues in the 1990s and by Edithe Pereira's team in 2014. In this article, we present the results of the technological analyses of the bifacial tools found in the cave, focusing on raw materials, techniques, shaping and retouching methods, and technical procedures. The analyses indicate careful knapping, with no mistakes, in hundreds of flakes in the shaping and retouching phases, as well as fragmented tools with flaws. Whenever possible, we compare the results to the data published by Roosevelt and colleagues in 1996 from the same site.

Este artículo analiza la arquitectura del período Clásico de Pahñú, un centro ceremonial en el noreste del valle del Mezquital, México. Esta arquitectura se distingue porque desarrolló un estilo local, integrando elementos de distintas tradiciones culturales. Por un lado, los conjuntos arquitectónicos de patio hundido siguen los estándares de la tradición del Bajío. Por otra parte, los edificios muestran rasgos de la arquitectura monumental teotihuacana y zapoteca. A partir de esta evidencia se concluye que Pahñú definió su identidad étnica estableciendo filiaciones políticas con las culturas del centro y el Bajío. Esta interpretación pone a prueba varias explicaciones previas que conciben el desarrollo regional durante el período Clásico como aculturación o resistencia a Teotihuacán. Asimismo, pone a prueba las interpretaciones que sostienen que la fusión cultural entre los grupos del centro y el Bajío comenzó hasta el Epiclásico. Finalmente, Pahñú es importante porque representa un pequeño centro político que mantuvo su liderazgo por unos seiscientos años, aprovechando su posición fronteriza entre el centro y el Bajío.

Anthropologists have demonstrated that having information about new settlements is crucial for drawing migrants. Pilgrimage to ritual landscapes and their shrines allows people, including Maya societies, to explore places where they can settle. They then establish or augment settlements around the landscape shrines, which explains the locations and growth of some centers. Migrants continue to make pilgrimages to shrines, such as sacred mountains, near their receiving settlements to enhance community cohesion through ritual contact with spiritual forces. In this article, I show that pilgrimage is an important element in the establishment of select migrant settlements and their community identity. I focus on Maya and Mesoamerican cultures, particularly at Mensabak in Chiapas, Mexico, and on supporting archaeological, historical, and ethnographic information. I conclude that Maya perceptions of movement, connectivity, and transformation in their world are linked to pilgrimage, migration, and community formation. Importantly, pilgrimage provides a religious variable, in addition to better-known economic, political, or demographic factors, to consider in migration.

Archaeological and ethnohistorical investigations in the south of the Colombian Plateau, in the Eastern Highlands, suggest that before European contact Guatavita was an important Muisca chiefdom—largely because of the prestige conferred by the presence of ceremonial centers in their territories, especially around the lakes in the hills surrounding the Guatavita-Guasca Valley. The fame of Lake Guatavita as the most important Muisca shrine was fueled by Spanish chronicles during the sixteenth and seventeenth centuries, which described it as the core of mass offering ceremonies or of lavish rituals for the chief's investiture, which fed both the story and the myth of El Dorado. This article presents the results of the archaeological survey done around the lake. The type and distribution of the material culture suggest that there was a shrine where small-scale ritual offerings took place, rather than conspicuous celebrations.

El estudio de la Misión Salesiana (siglos diecinueve y veinte) contribuye al conocimiento del impacto que las misiones religiosas tuvieron en América. Los registros históricos sugieren un cambio en la dieta, hacinamiento y alta frecuencia de enfermedades pulmonares infecciosas, como la tuberculosis. Muchos problemas de salud surgen de desequilibrios dietarios. La insuficiencia nutricional crónica hace que los individuos sean más susceptibles a las enfermedades infecciosas, y esto a su vez reduce la disponibilidad de nutrientes para la persona, creando una retroalimentación positiva. El objetivo de este trabajo es explorar el impacto que tuvo el contacto continuo en Patagonia Austral —específicamente en el caso de la Misión Salesiana— sobre la población originaria, a partir del análisis de marcadores metabólico-nutricionales e infecciosos y teniendo en cuenta el estado nutricional y estilo de vida de los individuos que allí habitaron. Para evaluar el cambio se compararon los resultados de los individuos de la misión con información previamente publicada y nuevas revelaciones de individuos del norte de la Isla Grande de Tierra del Fuego. Por un lado, se observó una elevada prevalencia de signos patológicos tales como hiperostosis porótica, cribra orbitalia, hipoplasia del esmalte y caries; por otro, fuentes documentales y estudios de isótopos estables indican un cambio en la dieta que conlleva una reducción en la variedad de alimentos. Los cambios producidos en el estilo de vida y la alta frecuencia de enfermedades infecciosas pudieron actuar sinérgicamente, influyendo en la drástica reducción del número de personas que habitaba dentro de la misión.

The development of freestanding stone sculpture by the Olmec people of Mesoamerica's Gulf lowlands has long been considered one of the defining artistic achievements of the Formative period. However, by the Middle Formative period the production of freestanding sculpture was often eclipsed by the contemporaneous creation of rock art outside the Gulf lowlands. In this article I argue that Gulf Olmec sculptors and audiences occasionally co-opted the aesthetic and ritual treatments of rock art at topographic shrines to construct and reinforce the sacred geographies of primary site cores. In so doing, Olmec elites converted the ideological power of the wild and the animate earth into a form of political capital.

In 2021, an Italian-Peruvian archaeological team began a research project in the Ancash Sierra to investigate the origins of early monumental architecture in the northern-central Andes. The large complex of Tumshukayko—located in the northern part of the town of Caraz in Ancash, Peru—was immediately found to be the most suitable site for this project. This report presents an initial description of the current state of the remains, topographical data, and test pit results. Preliminary data suggest that Tumshukayko is a multicomponent site comprising at least two mounds that were built during the Initial Formative period (2500–1500 BC).

This report presents new documentation of the external canal in the Late Postclassic site of Tetzcotzinco in the municipality of Texcoco, Mexico. This structure was previously considered a waterwork separate from the monumental water-management system discovered in the central part of the site. However, reanalysis of the course of this canal allowed us to reassess its function and revise the existing Tetzcotzinco maps. We propose that this structure formed part of the main water-management system of the site.
