La adaptación de los mayas postclásicos a las nuevas condiciones de vida surgidas a raíz de la crisis generalizada del final del período Clásico mediante respuestas resilientes se ha convertido en un tema de creciente interés por parte de los investigadores mayistas en las últimas décadas. El estudio de vestigios arqueológicos adscritos al Postclásico puede ayudar a entender por qué ciertas tradiciones fueron abandonadas, mientras que otras han perdurado a lo largo del tiempo, como es el caso de las ceremonias del culto a la lluvia. Ejemplo de ello son los hallazgos de ofrendas y otros vestigios arquitectónicos realizados en Chilonché, un antiguo asentamiento urbano maya fundado en la cuenca del río Mopán (Petén), cuya arquitectura y manifestaciones artísticas son un fiel exponente de la importancia política que tuvo el sitio en su dilatado período de ocupación. Los resultados de esta investigación, que combina los estudios arqueológicos y arquitectónicos con los análisis arqueométricos e iconográficos de las piezas cerámicas exhumadas, permiten afirmar que las ofrendas postclásicas halladas en un palacio de la acrópolis de Chilonché están íntimamente ligadas al acto de verter agua y a la imagen de Chaahk, y por lo tanto a rituales vinculados a la lluvia.

Este trabajo discute las estrategias vinculadas al aprovechamiento de animales durante dos ocupaciones del sitio San Francisco Inca (puna transicional de Chaschuil, Catamarca, Argentina): una incaica (ca. siglos catorce y quince dC) y otra preincaica (ca. siglos diez a trece dC). Los grupos agropastoriles preincaicos que ocuparon estacionalmente el sitio desarrollaron una estrategia de diversificación, intensificación y almacenamiento de los recursos de origen animal para hacer frente a la impredecibilidad puneña y al contexto regional de restricción ambiental. Esta incluyó la caza de vicuñas, la tendencia a evitar el sacrificio de llamas durante dicha ocupación, el procesamiento relativamente intensivo de partes de bajo retorno de los camélidos, el secado de elementos del esqueleto axial y, posiblemente, el consumo diferido de la médula ósea de los metapodios. Durante la ocupación incaica, el Estado organizó festines para legitimar su presencia en la región y sirvió comidas basadas fundamentalmente en los recursos brindados por animales silvestres capturados localmente (vicuñas y, en menor proporción, roedores, aves y guanacos). Además, se plantea la posibilidad de que en dichos eventos festivos se hayan realizado sacrificios de llamas y producido carne seca para su consumo diferido en otros pisos altitudinales o para el intercambio.

Excavators working in a ceremonial plaza group in the Classic period Lowland Maya city of Caracol, Belize, encountered thousands of pieces of chert and obsidian scattered above a royal tomb. A recent analysis of the chert from this context confirms that the assemblage included pieces from each stage of reduction in the production of blades. Taken together, the quantity of both chert and obsidian makes it the largest reported collection of lithic debitage found at the site and provides insight into the techniques of lithic crafters at Caracol. In this article, we consider the sequence of actions involved in the burial of a high-ranking individual and suggest that the layering of flaked stone above the tomb is reminiscent of other reported above-tomb contexts in the Maya Lowlands. Further, a technological analysis of this collection produced results similar to analyses of assemblages typically found in crafting-intensive residential groups. This finding suggests that lithic crafters throughout the city of Caracol donated flaked stone material for funerary events, providing a protective layer and sealing the grave below.

The attribution of osteological remains of a bird discovered in Preceramic deposits at Nemocón IV rockshelter (Sabana de Bogotá, Colombia) to Ara sp. (macaws) is confirmed through osteological and morphometrical analyses. Thirteen bones were recovered from two adjacent, arbitrary excavation levels; and are considered the remains of a single individual because of the rarity of the taxon, their similar size and taphonomic alteration, and the presence of paired elements. Radiocarbon dating of the macaw reveals it comes from the ninth millennium cal BP, the oldest date recorded from Nemocón IV. Paleoenvironmental data suggest that, during the deposition of the Preceramic levels at Nemocón IV, climatic conditions were close to those of today. The modern range of the macaws is outside these climatic parameters, and all modern Ara species are allochthonous to the Sabana de Bogotá, indicating the archaeological macaw was also allochthonous in Preceramic times. Analysis of the remains shows the macaw was not dismembered, so it is unlikely that it was used as food. Early conquest records indicate macaws were traded and maintained outside their natural ranges as pets, as a source of feathers, for use in rituals, or for a combination of uses.

In this article, we present the most significant results of the Monte Albán Geophysical Archaeology Project. Using ground-penetrating radar, gradiometry, and electrical resistance, we carried out a systematic survey of the site's Main Plaza to identify buried prehispanic features that might shed light on Monte Albán's early history. The most important discoveries include three buried structures dating between the Danibaan (500–300 BC) and Nisa phases (100 BC–AD 100). We argue that the largest structure, measuring 18 × 18 m, was probably a temple platform and that all three of the structures were razed and buried by the end of the Nisa phase at the latest. Furthermore, we contend that these events were part of a major renovation and expansion of the site's Main Plaza that occurred during a pivotal period of dramatic sociopolitical transformation in the Zapotec capital.

This article investigates the mechanisms by which different communities were articulated during the Late Intermediate period (ca. AD 1000–1450) in the Río Grande de San Juan Basin, also called the Chicha Region, located in the border region of Bolivia and Argentina. Through analyses of systems of pottery production, circulation, and consumption, we examine interaction networks, social integration, and alliance building at a regional level. Yavi-Chicha pottery from two sites in the Chicha Region—Chipihuayco, in the Talina Valley (Bolivia), and Finispatria, in San Juan Mayo (Argentina)—provide key insights into regional integration and constellations of practice through their localized technological style and shared consumption strategies. This study reveals that people of Finispatria incorporated the entire Yavi-Chicha-style household assemblage—partly produced in Chipihuayco, partly in Finispatria, or partly at some unknown location—into their everyday lives. We argue that the entire household ceramic repertoire of the study region played a fundamental and socially integrative role as it circulated across the region.

The peoples of southern Mesoamerica, including the Classic period Maya, are often claimed to exhibit a distinct type of spatial organization relative to contemporary urban systems. Here, we use the settlement scaling framework and properties of settlements recorded in systematic, full-coverage surveys to examine ways in which southern Mesoamerican settlement systems were both similar to and different from contemporary systems. We find that the population-area relationship in these settlements differs greatly from that reported for other agrarian settlement systems, but that more typical patterns emerge when one considers a site epicenter as the relevant social interaction area, and the population administered from a given center as the relevant interacting population. Our results imply that southern Mesoamerican populations mixed socially at a slower temporal rhythm than is typical of contemporary systems. Residential locations reflected the need to balance energetic and transport costs of farming with lower-frequency costs of commuting to central places. Nevertheless, increasing returns in activities such as civic construction were still realized through lower-frequency social mixing. These findings suggest that the primary difference between low-density urbanism and contemporary urban systems lies in the spatial and temporal rhythms of social mixing.

One of the most impressive examples of an Inca capacocha ceremony was discovered during an archaeological expedition to the summit of Misti volcano in 1998. The offerings at the site included several human sacrifices, along with fine ceramics and figurines made from gold, silver, and Spondylus sp. shell. One of the two burials appeared to contain the bones of males and the other of females. The sex was established based on the contents of the graves, because the fragile skeletal material had been badly affected by volcanic activity and exact identification was difficult to make in situ. To limit the risk of damage, the bones were excavated together with the surrounding soil and transported in frozen blocks to the Museo Santuarios Andinos of Universidad Católica de Santa María in Arequipa. This material was the object of a bioarchaeological investigation in February and March 2018. The results revealed that at least eight individuals had been buried in the graves. The findings have increased our understanding of the age categories and physical condition of the individuals chosen to be sacrificed during the capacocha ritual.

America's first urban centers may have been located in the Supe Valley, Peru. After investigating the location and the orientation of the main built structures, we show that it is not only the presence of the Supe River that determines their orientation but also that astronomical relationships within the orientation of the buildings dictate their setting within the valley. The southernmost position of moonrise on the horizon seems to be the most important astronomical target. There is the possibility of a trend toward attributing greater importance to the June solstice sunrise and the rising of certain stars or asterisms. These orientations could relate to specific moments throughout the year, in particular to seasonal rains, subsequent river flooding, and agricultural cycles. This is one of the earliest examples of the interaction of land- and skyscapes in human cultures and indeed the first in the Americas.

Our recent data, collected using remotely sensed imagery and unmanned aerial vehicle surveys, reveal the extremely well-defined patterning of archaeological plaza villages in the Brazilian Acre state in terms of size, layout, chronology, and material culture. The villages comprise various earthen mounds arranged around central plazas and roads that radiate outward from, or converge on, the sites. The roads connected the villages situated 2–10 km from each other in eastern Acre. Our study attests to the existence of large, sedentary, interfluvial populations sharing the same sociocultural identities, as well as structured patterns of movement and spatial planning in relation to operative road networks during the late precolonial period. The plaza villages of Acre show similarity with the well-documented communities organized by road networks in the regions of the Upper Xingu and Llanos de Mojos. Taking into consideration ethnohistorical and ethnographic evidence, as well as the presence of comparable archaeological sites and earthwork features along the southern margin of Amazonia, we suggest that the plaza villages of Acre were linked by an interregional road network to other neighboring territories situated along the southern Amazonian rim and that movement along roads was the primary mode of human transport in Amazonian interfluves.

Structure M13-1 is a public monumental building in the heart of ancient El Perú-Waka’, Petén, Guatemala, and is the location of Burial 61, an entombed Late Classic (seventh-century) ruler. In this report, we discuss mortuary evidence that we believe permits identification of the interred as the historically known queen, Lady K'abel.

As insignia of power and prestige, Inka unku (tapestry tunics) communicated the strength and extent of Inka sociopolitical hegemony in the Andes. Of the 36 known full-size examples in museum collections, only one, found in Argentina, comes from outside Peru. This article investigates another recently excavated unku found out of context on Chile's northernmost coast. To confirm its authenticity, we compiled a database showing the technical and stylistic attributes of previous finds for comparison. We conclude that this artifact is indeed a new type of unku and that the discovery affects our understanding of the complex relationship between the people of this province and the Inka state.

Recent investigations at Cahal Pech, Belize, documented a previously unrecognized Middle Preclassic (700–500 cal BC) E-Group complex. Located in an open public plaza, the monumental complex likely functioned as a forum for communal public events. In the Late Preclassic, the E-Group was replaced by an ancestor shrine where several royal tombs are located, as well as buildings separating public civic space from private elite space. These shifts in monumental construction temporally track the development of ideological manifestations of power and provide evidence for the formalization of dynastic rulership by an emerging elite class.
