Se presentan los resultados del recorrido de superficie realizado en la comunidad de Santo Domingo Tonaltepec en la Mixteca Alta de Oaxaca, en el que se identificaron y registraron 43 nuevos sitios arqueológicos datados a las fases Ramos (alrededor de los 300 aC hasta los 250 dC), Las Flores (aproximadamente 250-900 dC) y Natividad (aproximadamente 900-1521 dC). Estos nuevos sitios se contextualizan en el ámbito regional al relacionarlos con los sitios urbanos identificados para cada una de estas fases en los valles adyacentes de Coixtlahuaca, Nochixtlán, Tamazulapan y Teposcolula. Basados en estos datos, consideramos que Tonaltepec se encontró relativamente aislado y fuera del control de los sitios urbanos tempranos durante Ramos; que se transformó en un asentamiento fronterizo entre las entidades políticas durante la fase Las Flores; y que aprovechó los beneficios de localizarse sobre la ruta de comunicación entre importantes reinos mixtecos durante Natividad. La localización de Tonaltepec, relativamente lejos de los principales valles, pero a la vez entre ellos, le otorgó ventajas que supo aprovechar a través de la historia de desarrollo político de la región.

The early colonial period witnessed new scales of connectivity and unprecedented projects of resource extraction across the Spanish Americas. Yet such transformations also drew heavily on preexisting Indigenous landscapes, technologies, and institutions. Drawing together recent discussions in archaeology and geography about mobility and resource materialities, this article takes the early colonial route as a central object of investigation and contributes to new emerging interpretive frameworks that make sense of Spanish colonialism in the Americas as a variable, large-scale, and materially constituted process. Using three case studies—the ruta de Colón on the island of Hispaniola, the routes connecting the southeastern Caribbean islands with mainland South America, and the ruta de la plata in the south-central Andes—we develop a comparative archaeological analysis that reveals divergent trajectories of persistence, appropriation, and erasure in the region's routes and regimes of extraction and mobility during the fifteenth and sixteenth centuries.

The contents, context, and date of Problematical Deposit 50 bear on the origin, function, and meaning of Teotihuacan stylistic traits in the Southern Maya Lowlands. Archaeological data and material culture research appear to support emulation and adaptation by local rulers and elites, while an actual presence of Teotihuacanos is asserted by epigraphy and iconography. PD 50, the partial contents of a probable Early Classic chamber burial, appears to support local emulation, but an extraordinary pottery vessel, nicknamed here the “Arrival Bowl,” implies direct contact. The chronology and archaeological context demonstrate that the appearance of Teotihuacan stylistic traits at Tikal during the later Early Classic period is functionally distinct from the goods distributed over an interregional interaction sphere of much longer duration in which both Central Mexico and the Maya area participated. Furthermore, together with other features at Tikal, PD 50 suggests that adoption of Teotihuacan ideology by Tikal's elite was eventually met with resistance that contributed to the violence at the end of the Early Classic period that is manifested in the archaeological record.

We revisit the age and typological character of “Pox Pottery” that was reported in the 1960s by Charles Brush who considered it to be uniquely early (~2440 BC). Investigating the same two sites in coastal Guerrero where Brush excavated, we recovered Early Formative ceramics, some with the “pox” attribute. Here, we report potsherd frequencies for these deposits at both sites according to regional ceramic typologies, as well as AMS 14C dates used to establish a Bayesian stratigraphic chronology for each site to better constrain the age of these Early Formative period deposits. We argue that “Pox Pottery” is not a ceramic type per se and that the “pox” attribute occurs in multiple Early Formative period ceramic types. The earliest pottery is similar to other Red-on-Buff ceramic traditions from the Central Mexican Highlands and west of the Isthmus of Tehuantepec. Our chronological work demonstrates that these ceramics date between 1820 and 1400 cal BC, consistent with other recent studies indicating an early age of Red-on-Buff ceramics and suggesting shared cultural traditions distinct from the contemporary Locona interaction sphere that emerged in parallel.

The Late Intermediate period in the south-central Andes is known for the widespread use of open sepulchres called chullpas by descent-based ayllus to claim rights to resources and express idealized notions of how society should be organized. Chullpas, however, were rarer on the coast, with the dead often buried individually in closed tombs. This article documents conditions under which these closed tombs were used at the site of Quilcapampa on the coastal plain of southern Peru, allowing an exploration into the ways that funerary traditions were employed to both reflect and generate community affiliation, ideals about sociopolitical organization, and land rights. After a long hiatus, the site was reoccupied and quickly expanded through local population aggregation and highland migrations. An ayllu organization that made ancestral claims to specific resources was poorly suited to these conditions, and the site's inhabitants instead seem to have organized themselves around the ruins of Quilcapampa's earlier occupation. In describing what happened in Quilcapampa, we highlight the need for a better understanding of the myriad ways that Andean peoples used mortuary customs to structure the lives of the living during a period of population movements and climate change.

The city of Teotihuacan (AD 1–550) was a major multiethnic urban center that attracted migrants from as far away as west Mexico and the Maya region. Past research in the Tlajinga district at Teotihuacan using oxygen isotopes from human remains estimated that nearly 30% of the population of Tlajinga 33, a single apartment compound, were migrants. This study takes a dual-isotope approach (87Sr/86Sr and δ18Op) to reevaluate the proportion of in-migration at Tlajinga and includes data from two additional apartment compounds, Tlajinga 17 and 18 (n = 23). New results indicate that migrants comprised ~45% of the Tlajinga population. Previously acquired radiocarbon dates combined with mortuary and isotope data suggest that immigration to Tlajinga was highest during the first centuries of compound occupation. Nevertheless, migration was a continual process throughout its history. Additionally, a new finding suggests that residents of Tlajinga 33 ingested foods with higher 87Sr/86Sr ratios than did those of Tlajinga 17 and 18. We hypothesize that the incorporation of imported lime for the nixtamalization process skewed the 87Sr/86Sr ratios of human remains, a potentially important finding for future studies at Teotihuacan.

Investigations of the Proyecto Arqueológico Tlajinga Teotihuacan (PATT) in 2019 focused on the southern neighborhood center of this cluster of non-elite residences in the southern periphery of the ancient Mexican metropolis. Our objective was to better understand the social infrastructure of public space within the district and how it tied its inhabitants together. Our methods included excavations at two large architectural complexes, geophysical prospection of these and adjacent structures and plazas, and chemical residue analysis of floors and sediments. They revealed architecturally elaborate complexes decorated with mural painting that appear to have been the loci of civic-ceremonial activities. Materials from the excavated portions of the complexes are inconsistent with residential uses, although it is possible that local elites lived elsewhere in the complexes or in others located nearby. The investigations therefore demonstrate that the semipublic spaces of neighborhood centers were distributed as distantly as this periphery of Teotihuacan and could be as elaborate as those in the urban epicenter, underscoring the city's more muted social inequality.

The collapse of the Tiwanaku state around AD 1000 resulted in dramatic changes in the areas of its former colonies such as the Moquegua Valley, which featured the largest Tiwanaku communities outside the Altiplano. The inhabitants of these former colonies were forced to relocate to the areas north of Moquegua, including the Tambo River estuary (Arequipa Department, Province of Islay). This relocation has been confirmed at La Pampilla 1, where a large graveyard featuring funerary contexts of the postcollapse communities of Tiwanaku-Timulaca was found, with a calibrated 14C date between the eleventh and thirteenth centuries AD. In this article we discuss the results of excavations and analyses conducted at the La Pampilla 1 graveyard, the first systematically researched Tiwanaku site in the Tambo Valley: these findings confirm the existence of a relatively large, terminal-phase Tiwanaku population, represented by Tumilaca funerary contexts.

This article reconstructs the final diet of sacrificed domestic camelids from Huanchaquito-Las Llamas to understand whether feeding was part of the ritual practice. The site is situated on the northern coast of Peru and is dated to the fifteenth century AD (Late Intermediate period; LIP). It was used by the Chimús to kill and bury a large number of camelids, mostly juveniles. We reconstructed the final meal of 11 of the sacrificed individuals by analyzing starch grains derived from the associated gut contents and feces. The starch grains were well preserved and allowed for the determination of five plant taxa. The comparison with previously published and new stable isotope analyses, which provide insights into long-term diet, indicates that the Chimús managed their herds by providing maize as fodder and allowing them to graze on natural pasture; yet they reserved special treatment for sacrificial animals, probably bringing them together a few hours or days before the sacrificial act. We show for the first time the consumption of unusual food products, which included manioc, chili peppers, and beans, as well as cooked foods. Our study provides unique information on Chimú camelid ritual and herding practices.

Archaeological studies at Coxcatlan Cave in the Tehuacan Valley of southern Puebla, Mexico, have been instrumental to the development of the chronology for the region and for our understanding of the origins of food production in the Americas. This article refines the Preceramic chronology of the Tehuacan Valley by presenting 14 new accelerated mass spectrometry (AMS) radiocarbon ages from faunal bone samples uncovered from early depositional levels of the rock shelter. Although bones associated with the El Riego (9893–7838 cal BP), Coxcatlan (7838–6375 cal BP), and Abejas (6375–4545 cal BP) phase zones of the cave yielded ages similar to those of the previously proposed chronology for the region, bones from the Ajuereado phase zones at the base of the cave yielded surprisingly old ages that range from 33,448 to 28,279 cal BP, a time prior to the Last Glacial Maximum. Because these early ages are many thousands of years older than current models estimate for the peopling of the Americas, they require reassessments of the artifacts and ecofacts excavated from these early zones.

En este trabajo examinamos los vínculos existentes entre una serie de cambios arquitectónicos-espaciales que tuvieron lugar en el ingenio azucarero Lastenia durante las últimas décadas del siglo diecinueve y las dinámicas sociales que caracterizaron a la industria azucarera en estos años. Para ello, analizamos una serie de viviendas destinadas a obreros y propietarios de la unidad productiva, apoyándonos en metodologías procedentes de la arqueología histórica, la arquitectura, el diseño y el análisis arqueológico de configuraciones espaciales. Los resultados obtenidos indican que el entorno fabril estudiado estuvo caracterizado por relaciones sociales jerárquicas, de control social y disciplinarias que quedaron plasmadas a nivel arquitectónico y en la distribución espacial de las estructuras analizadas. Si bien el estudio de las relaciones sociales en contextos agroindustriales azucareros ha sido desarrollado desde disciplinas como la historiografía, ha recibido poca atención por parte de la arqueología.

Recent excavations at the site of Gallon Jug, a minor center in northwestern Belize, revealed multiple patolli boards incised into a well-preserved plaster floor in an unvaulted platform. A significant artifact deposit was placed directly on top of the patolli boards. In this report we describe the architectural context, associated artifact deposit, and the patolli boards themselves.

Se presentan los resultados del examen de un perfil estratigráfico ubicado en el sureste del Complejo Maranga-Lima, en el valle bajo del Rímac. Las evidencias recuperadas permiten fechar la ocupación de dicho sector entre los 620 dC y los 780 dC. Se analiza también la geomorfología vinculada con la ocupación humana, que incluyó eventos aluviales asociados con su abandono. También se analiza una columna palinológica que sugiere un ecosistema semi-árido impactado por el establecimiento de Maranga.
