A través de la morfometría geométrica, este estudio explora la influencia del contexto cronológico y de procedencia en la variabilidad morfológica de 75 anzuelos de concha de Choromytilus chorus provenientes de siete sitios arqueológicos de la comuna de Taltal, en la costa sur del Desierto de Atacama, Chile. Los resultados muestran diferencias significativas en las formas de los anzuelos provenientes de distintos sitios y períodos. El rasgo que explica el mayor porcentaje de variación morfológica es el largo de una de las puntas, seguido por la abertura del anzuelo. Se identifican tres momentos clave en la evolución morfológica de estos artefactos. Entre 8500 y 7500 cal aP aparecen los primeros anzuelos, predominantemente sin vástago y de abertura amplia pero variable. De 7500 cal aP en adelante, la tecnología prolifera y se diversifica: los anzuelos sin vástago y con abertura amplia siguen predominando, pero formas con vástago y abertura media también están presentes en el kit de pesca. Finalmente, entre 5500 y 4500 cal aP el número de anzuelos disminuye, desaparecen las formas circulares y se mantienen las formas con vástago, pero con abertura más estrecha. El caso de estudio de Taltal contribuye a enriquecer el conocimiento sobre la tecnología del anzuelo en concha a lo largo del Pacífico.

Paleodemographic simulations are rare in the Maya region, because generally the skeletal collections do not represent well the ancient living population, are poorly preserved, and lead to flawed age-at-death estimations. The skeletal collection of Xcambó, however, is suitable for paleodemographic analysis and is large enough to enable comparison of paleodemographic trends between the Early (AD 250–550) and Late Classic (AD 550–750) periods. Three demographic simulations were generated; two relied on growth rates calculated from the site's previous archaeodemographic data, and a third simulation was based on a stationary scenario by applying Weiss's (1973) and Séguy and Buchet's (2013) models. All simulations indicate that Xcambó’s Late Classic population was growing faster than its Early Classic peers, with higher rates of survivorship and more severe mortality rates. We argue that the differences are more likely due to shifts in lifestyle and wealth than to environmental changes, as is confirmed by other bioarchaeological and skeletal indicators.

In the Lake Titicaca Basin during the Late Intermediate period (LIP; AD 1100–1450), people's lives were overwhelmingly structured by warfare. Previous research in the region has shed light on how martial conflict between and possibly among competing ethnic groups motivated people to live in fortified villages on defensive hilltops. At the same time, there was a centuries-long drought that threatened agricultural production. Little is known about the plant use of people living in hillforts during this arduous time. Drawing on macrobotanical information collected from Ayawiri, one of the largest hillforts in the northern Titicaca Basin, I argue that the food stuffs and plants used were locally grown. Additionally, these findings indicate a possible departure from earlier symbolically charged and ritually important plant consumption practices based on the lack of imported maize. This research sheds light on how people adapted their domestic and agricultural strategies to warfare and climate change during the LIP.

San José 520 is a Classic period hamlet of single-family residences in the urban periphery of Teotihuacan, just beyond the southeast edge of the city. Three burial features were associated with one of the residences, AF2. One of the features contained the burial of a single adult, another the successive burials of eight adults and one neonate, and the third held a neonate. We analyzed 29 bone and enamel samples from the adults for bioapatite phosphate oxygen-isotope composition; we also considered isotopic data for another five bone samples analyzed in a separate project. The isotopic results suggest a pattern of birth in the Teotihuacan region and then movement in early childhood to a “relocation” region, the geographic location of which is unknown. Later, probably in adolescence, the individuals returned to live, and eventually die, in San José 520. Without knowing more about the occupation of the relocation region, it is difficult to say what concerns or beliefs underlay this unusual but long-established settlement system.

En el Viejo Mundo algunos arqueobotánicos, a partir de fuentes etnográficas y etnobotánicas, desarrollaron modelos interpretativos sobre el procesamiento de cereales, pudiendo interpretar antiguas prácticas de preparación y consumo a partir de restos arqueobotánicos. En el caso del Noroeste argentino, los estudios etnobotánicos —junto a otros de corte etnohistórico o histórico— han permitido abordar el análisis de restos arqueobotánicos procurando identificar los trazos materiales de comportamientos vinculados a diversas preparaciones culinarias en las que participaron distintas plantas y partes de las mismas. El objetivo del trabajo es analizar las posibles técnicas de procesamiento de los restos del género Chenopodium recuperados del sitio de Soria 2 (Valle de Yocavil), del período Formativo, a partir de un modelo etnobotánico y experimental. Se recuperaron 23 ejemplares del género Chenopodium, los cuales pertenecen a Chenopodium sp., Chenopodium quinoa var. quinoa y C. cf. carnosulum. El 57% de los restos presentaron evidencias de procesamiento. Los restantes mostraron deterioros que, si bien permitieron identificarlos, no hicieron posible la identificación de marcas de procesamiento. La aplicación de este tipo de estudios a restos arqueobotánicos permite un acercamiento más detallado sobre las prácticas poscosecha llevadas a cabo por las sociedades en el pasado.

The famous greenstone figure known as the Tuxtla Statuette is one of only 12 objects known to bear an epi-Olmec inscription and was the first to become known to scholarship. For more than a century its original find-spot was imprecisely and erroneously identified as lying in the township of San Andrés Tuxtla or, more generally, in the Tuxtla Mountains. Correspondence in the National Anthropology Archives of the Smithsonian Institution documents that the figure was found on the Hacienda de Hueyapan de Mimendi, near the colossal head of Tres Zapotes. Archival research in Mexico's National Museum of Anthropology and the Archivo General del Estado de Veracruz, as well as interviews with descendants of owners of the Hacienda de Hueyapan and the statuette, allow us to confirm several features of the Smithsonian correspondence. The data indicate that the statuette was found within or very near the epi-Olmec regional center of Tres Zapotes and within the township of Santiago Tuxtla.

We explored the site context of a late Holocene shell midden on the coast of Los Vilos in north-central Chile (31°51′ S, South America) to better understand the spatial organization of short-term, small-sized hunter-gatherer campsites. The Dunas de Agua Amarilla (LV 007) site comprises 14 separate surf clam refuse deposits. Extensive stratigraphic excavations of the shell middens and the areas free of residue allowed interpretation of potential activity areas bounded by hearths, the shell middens, and a possible dwelling space. Late Holocene campsites in the area correspond to brief occupational events framed within littoral residential mobility, in which predictable coastal resources became a staple for groups residing and circulating over long periods in the area. Data on shell midden composition and the spatial distribution of site features shed light on the organizational dynamics of dwelling and activity spaces of coastal hunter-gatherers of the South Pacific.

In premodern economic systems where the social embedding of exchange provided actors with the ability to control or monopolize trade, including the goods that enter and leave a marketplace, “restricted markets” formed. These markets produced external revenues that could be used to achieve political goals. Conversely, commercialized systems required investment in public goods that incentivize the development of market cooperation and “open markets,” where buyers and sellers from across social sectors and diverse communities could engage in exchange as economic equals within marketplaces. In this article, we compare market development at the Late Postclassic sites of Chetumal, Belize, and Tlaxcallan, Mexico. We identified a restricted market at Chetumal, using the distribution of exotic goods, particularly militarily and ritually charged obsidian projectile points; in contrast, an open market was built at Tlaxcallan. Collective action theory provides a useful framework to understand these differences in market development. We argue that Tlaxcaltecan political architects adopted more collective strategies, in which open markets figured, to encourage cooperation among an ethnically diverse population.

Este trabajo contribuye, desde la bioarqueología, al estudio de la dieta de las poblaciones que habitaron el sur del Noreste argentino (NEA) durante el Holoceno tardío (desde ca. 2000 aP). Específicamente, se evalúa el consumo de vegetales y los posibles modos de procesamiento de los alimentos. Se revelan diferentes bioindicadores bucodentales en tres muestras bioarqueológicas de tres sectores geográficos: Delta superior e inferior del río Paraná (entre ca. 570 y 850 cal aP) y cuenca inferior del río Uruguay (ca. 2000 cal aP). Los bioindicadores observados en las tres muestras (1.355 dientes y 1.693 alveolos) se ajustan a lo esperado para economías mixtas de caza-pesca-recolección y horticultura. Los recursos animales constituyeron el componente principal de la alimentación, mientras que el consumo de vegetales fue un importante complemento en la dieta. Se registran diferentes modos de procesar los alimentos que atenuaron el estrés masticatorio y se destaca que la dieta habría sido más abrasiva en la muestra del Uruguay inferior en comparación con las otras dos muestras. Los resultados obtenidos, al integrarse con información disponible de otras líneas de análisis (e.g., arqueobotánicas, zooarqueológicas), aportan y amplían el conocimiento sobre la alimentación de las poblaciones prehispánicas del sur del NEA.

The Terminal Classic period (ca. AD 800–1000) in the Southern Maya Lowlands witnessed a precipitous decline in the erection of carved stone monuments, a decline that corresponds to shifts in political ideologies and the disappearance of many prominent royal dynasties. Although Southern Lowland sites are often considered peripheral to the events and innovations occurring elsewhere in Mesoamerica during this time, a recently discovered stela, Stela 29, at the site of Ucanal in Peten, Guatemala, underscores the active role of the site in broader political movements in the ninth century. Our iconographic, textual, and stylistic analysis of this stela, in concert with other Terminal Classic monuments from the site, reveals a vernacular cosmopolitan aesthetic whereby local Classic Maya styles were infused with images and elements that referenced connections with peoples from northern Yucatan, the Gulf Coast, and Central Mexico.

This article discusses a Mapuche Indigenous mortuary context of the nineteenth century from the middle valley of the Negro River in northern Patagonia, Argentina, which is characterized by a double burial of a man and a woman. The use of both archaeological and ethnohistorical data allows us to hypothesize that the burial is of a man with a high status in the political and military hierarchy (cacique or capitanejo) and that the corpse of the woman was one of his wives who was sacrificed so she could accompany the man in his trip to Allhue Mapu, the land of souls. We contextualize this site with existing knowledge about the suttee practice in the Pampas and Norpatagonia during the eighteenth and nineteenth centuries. This case is an example of the burial ritual known as suttee that occurred between the last decades of Indigenous autonomy (1850–1880) and the first decades after the state conquest of their territory (1880–1900).

El registro de Canis familiaris en contextos arqueológicos resulta cada vez más frecuente en Sudamérica. En este escenario, este trabajo discute su rol económico y social dentro de las sociedades indígenas prehispánicas. Se presentan nuevos hallazgos de perros procedentes de cinco sitios arqueológicos del Noreste argentino. La muestra estudiada incluye siete especímenes craneales y uno poscraneal correspondientes a individuos jóvenes y adultos, de tamaños medianos (13-23 kg). Algunos de los especímenes presentan huellas de corte y marcas de carnívoros. Tres nuevas fechas taxón ubican a la muestra entre aproximadamente 2500 y 900 cal aP. Se concluye que C. familiaris presenta edades y tamaños ligeramente mayores a los registrados previamente. Asimismo, la evidencia antrópica indica procesamiento y consumo de esta especie. Las dataciones extienden el rango cronológico conocido previamente para este taxón en Argentina, Brasil y Uruguay. Su presencia se vincula a cazadores-recolectores-pescadores y horticultores, con una marcada adaptación fluvial durante el Holoceno tardío.
