This study uses isotope and microbotanical data from the analysis of teeth and dental calculus to investigate camelid diet and foddering practices at Quilcapampa (AD 835–900). By providing taxonomically specific evidence of foods consumed, botanical data from dental calculus complement the more general impressions of photosynthetic pathways obtained through isotopic analysis. Results suggest that the camelid diet incorporated maize (Zea mays), algarrobo (Prosopis sp.), potato chuño (Solanum sp.), and other resources. The life-history profile of one camelid (Individual 3) reveals dietary change from mainly C3 plants to more C4 plant contributions as the animal aged. This pattern is supported by carbonate isotope results indicating that this individual spent its youth in the mid-valley ecozone before becoming more mobile later in life. As this life-history example shows, isotopic and microbotanical analyses are complementary approaches, clarifying a pattern of seasonal transhumance that linked the lives of humans and animals along the Middle Horizon (AD 600–1000) caravan networks that crisscrossed the central Andes.

In precolumbian insular Caribbean archaeological sites, domestic dog (Canis familiaris) remains have been recovered from varied contexts, such as formal burials, in refuse deposits, and as modified artifacts, indicating their complex and multifaceted role within indigenous societies. In this study, isotopic and morphometric analyses provide biochemical and morphological correlations to assess this differential treatment. We examined collagen values (n = 21) of carbon (δ13Cco) and nitrogen (δ15N), and enamel values (n = 81) of carbon (δ13Cen), oxygen (δ18Oen), and strontium (87Sr/86Sr) of dog remains from 16 precolumbian sites. Five comparative parameters were used to assess dietary variations between different groups: buried versus nonburied, local versus nonlocal, Greater versus Lesser Antilles, chronology, and modified versus unmodified remains. The only statistically significant difference in diets was between local and nonlocal dogs. Sufficient data were available to conduct isotopic mixing models using the FRUITS statistical program on four individuals for which depositional and morphological data were available. Results of dietary modeling indicate an unexpectedly heavy reliance on plant foods consistent with intentional feeding. This approach highlights the utility of combining isotope analysis, dietary models, morphometrics, and depositional context to provide comprehensive biographic overviews of individual animals.

Increasingly, archaeological research in Amazonia is revealing complex precolonial occupation in areas around riverine confluences. In 2014, the first site-based archaeological investigations were undertaken in Gurupá, Pará, Brazil, a municipality that spans the region of the Xingu-Amazon confluence. The Portuguese controlled access to Amazonia from 1623 onward through a network of settlements organized around Gurupá. Results from extensive excavations of terra preta sites, landscape archaeology, and analysis of ceramic evidence suggest that this was also a precolonial crossroads. Carrazedo, once a booming historical town (Arapijó), sits atop a significantly larger terra preta site. Excavations in historical and precolonial sectors of Carrazedo found well-preserved remains, including a precolonial house terrace complex. The extent of terra preta and earthworks at Carrazedo indicate that the precolonial occupation was more intensive than the colonial-historical period occupation. Regional survey revealed colonial-historical period sites consistently overlying expansive precolonial sites, the density and extent of which suggest a major precolonial center at the Xingu-Amazon confluence. Overall, ecological and landscape modifications appear to have been more intense in the precolonial past than during later periods. Short- and long-distance settlement networks also differed during the two periods. This as-of-yet understudied region promises to shed new light on deep-time human-environment interactions and spatial organization in the humid tropics of Amazonia.

We present new data on a class of ceramics called Tiltepec yellow wares, dated to the Late and Terminal Formative period occupations at Cerro Jazmín, Oaxaca (300 BC– AD 300). Evidence from 27 radiocarbon-dated ceramic assemblages indicates that Tiltepec yellow wares are a distinct ceramic type. Instrumental Neutron Activation Analysis (INAA) results further confirm the wares’ identification. Defining Tiltepec yellow wares as a type apart from Classic-period orange ceramics allows the reassessment of the regional settlement sequence, previously understood to indicate widespread settlement abandonment in the Terminal Formative period. The new data suggest that Cerro Jazmín had a more continuous urban occupation than previously thought.

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.

Using textile production in Postclassic Western Mesoamerica as a case study, this article explores how to differentiate low levels of craft production caused by household provisioning from low levels of craft production due to market reliance and regional specialization. I use a sample of 52 excavated site/phase components to establish baselines for the intensity of production and to evaluate whether participation in the market allowed craftspeople in some regions to underproduce textiles relative to local needs. Highland and lowland sites have comparable low frequencies of spindle whorls during the Early Postclassic, which I interpret as characteristic of household self-sufficiency. Whorl frequencies increase above this baseline earlier and to a higher degree in lowland sites than in highland sites. During the Late Postclassic, some regions may have formed pairs of over- and underproduction zones linked by the market. Because of changes in spinning technology, it is not possible to extrapolate the results of this study to earlier time periods. I then present data from Calixtlahuaca as an example of how macroregional data can be used to interpret craft production at a particular site. Textile production at Calixtlahuaca was generally low, but this was more likely a function of a strong dependence on maguey fiber, rather than underproduction caused by a reliance on the market.

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.

In Mesoamerica, the Early Postclassic (AD 900–1200) is characterized by the long-distance circulation of pottery with a very hard and shiny coating with a metallic aspect, known as Plumbate ware. Plumbate is linked stylistically to the Toltec culture but was produced in workshops in Soconusco (Chiapas). The discovery of a similar collection of sherds during recent work at the site of El Palacio (Zacapu, Michoacán) shows that Plumbate ware also reached this region of Western Mexico. We carried out instrumental neutron activation analyses (INAA) on 11 of the Zacapu fragments and compared the results to the data from ceramic pastes from the region of Soconusco and Pátzcuaro Basin (Michoacán). Ten sherds were produced in Michoacán and are thus a local imitation, whereas the last fragment corresponds to a Tohil-type Plumbate paste and was transported over a long distance. This raises questions of the modalities for the circulation of this pot and the conditions allowing for production of an imitation (transfer of technical know-how?), which we suggest is linked to the Toltec culture in the center of Mexico.

Se presentan los resultados del análisis de restos óseos y dentarios de micromamíferos (≤1 kg) recuperados en Vaquería Gruta 2 (VQG2), un sitio arqueológico localizado en el piedemonte alto de la precordillera de Mendoza (Argentina) con dataciones correspondientes al Holoceno tardío. Estos resultados se comparan con aquellos reportados para conjuntos óseos de micromamíferos cordilleranos del Centro-Occidente Argentino. Se realizó un análisis tafonómico para aproximarse a los posibles agentes acumuladores del conjunto óseo, sobre la base de abundancias relativas, patrones de fractura y digestión. Se analizaron variables orientadas a evaluar la actividad antrópica, tales como huellas de corte y termoalteraciones. Los resultados también se compararon con valores reportados en estudios tafonómicos actualísticos regionales para distintos depredadores. El análisis tafonómico permitió determinar que fueron aves rapaces los agentes responsables de la acumulación ósea recuperada en VQG2. Esta misma fue producto, probablemente, de una acumulación mixta. Asimismo, se realizó un análisis de la composición taxonómica de VQG2. Tanto la presencia de especies extirpadas en el registro arqueológico (Reithrodon auritus) como la mayor diversidad y equitatividad en dicho registro, en comparación con los ensambles actuales de micromamíferos, permiten pensar en un escenario de mayor heterogeneidad ambiental durante el Holoceno tardío, con mayor disponibilidad de parches de recursos que en el presente.

Este artículo examina, desde una perspectiva etnohistórica, las relaciones económicas y sociales entre los choles del Manché, lacandones y acaláes, hablantes de choltí, de las tierras bajas mayas del sur, con los k’ekchi’es del Ah Xoy y la Verapaz, basadas en los agrosistemas de producción de la triada de cacao-achiote-vainilla, durante los siglos dieciséis y diecisiete. El intercambio de cacao y achiote por plumas de quetzal, algodón, copal, sal, así como hachas y machetes de origen europeo, constituyó un complejo sistema de intercambio entre choles, lacandones y k’ekchi’es. Se establecieron relaciones entre puntos de encuentro y puertos de entrada de gran importancia para entender los sistemas de comercio prehispánicos. Entre 1689 y 1695 las poblaciones choles y lacandonas fueron sometidas por los españoles y reubicadas fuera de sus territorios, lo que ocasionó su extinción. Con la desaparición de estos grupos se pensó que el conocimiento del cultivo asociado de cacao-achiote-vainilla se había perdido; sin embargo, este trabajo demuestra que los kekchi’es se convirtieron en receptores de esa sabiduría. Este artículo analiza el impresionante agrosistema cacao, achiote y vainilla de los antiguos choles y lacandones y su pervivencia hasta la actualidad en los huertos especializados de los k’ekchi’es del norte de Alta Verapaz.

AMS radiocarbon dating of two modified pearls from the Covacha Babisuri site, Espíritu Santo Island, Baja California Sur, México, corroborates associated midden dates suggesting that traditional indigenous use and modification of pearls as items of adornment began at least 8,500 years ago. To our knowledge, these are the oldest modified pearls found in dated archaeological contexts anywhere in the world. The presence of similarly modified pearls in later components at Covacha Babisuri suggests that this custom continued throughout the Middle Holocene, and ethnohistoric accounts indicate that similar modifications of pearls continued up until the Historic Era. These data show a long history of cultural continuity in the region in pearl harvesting, modification, and use as adornment.

We investigated foodways at Real Alto, an early Formative (4400–1800 BC) Valdivia site in coastal Ecuador, using starch and phytoliths recovered from 50 stone tools from three residential and two ceremonial structures, as well as 46 human dental calculus samples, to explore how food reflects the social relationships and economy of the community. Maize was important in daily meals and ceremonial foods by the Middle Valdivia (2800–2400 BC), but it was only one component of an agricultural system that included yuca, arrowroot, llerén, canna, yam, jackbean, squash, gourd, chili, and cotton. Ceremonial and everyday foods at Real Alto did not differ: actions surrounding food were both domestic and ceremonial, depending on context. Households had equal access to annual crops and to root-tubers with longer growing seasons. Gelatinized starch was commonly recovered on tools, indicating the processing of cooked foods. Dental calculus residues confirmed common consumption of cooked foods, fruits, and root-tubers. Cultivating crops with different water and growing season requirements necessitated diverse practices, potentially including selection of short-season varieties, hand watering, and growing crops over multiple rainy seasons. The latter two practices required increased labor inputs: access to labor was likely a key element supporting the nascent social hierarchy that emerged by the Middle Valdivia.

Este artículo examina la organización política de la ciudad prehispánica de Chichén Itzá, Yucatán, México, durante el reinado de K'ak' Upakal K'inich K'awil en la segunda mitad del siglo IX dC. Las interpretaciones políticas y territoriales que presentamos se basan en un entramado cronológico en el que entendemos los sectores del Chichén Itzá “Maya” y el Chichén Itzá “Tolteca” como dos periodos diferentes y secuenciales. Examinamos los cambios que aparecen en el período Clásico terminal, tales como las nuevas características no Mayas, el uso de glifos y nombres de origen foráneo, así como dioses de las Tierras Altas de México y nuevos tipos de edificios. En esta contribución también mostramos cómo el sistema interno de organización social cambió de un modelo de monarquía de un rey absoluto, identificado con la divinidad, a un tipo de gobierno más estructurado e incluyente, con mayor poder de la nobleza. Finalmente, proponemos un patrón de asentamiento que refleja esta nueva organización sociopolítica.

The site of Izapa, though famous for its unique “Izapan” style monuments, has lagged behind many other Mesoamerican centers in archaeological research. As revisions of important Mesoamerican chronologies are underway, Inomata and colleagues (2014) have questioned whether monument production at Izapa has been misplaced chronologically. This article applies new data from the Izapa Household Archaeology Project to assess Inomata and colleagues’ (2014) proposal for a shift in the chronology at Izapa. It specifically assesses the chronology for the Formative to Classic period transition at Izapa, from 100 BC to AD 400, with new excavation data, ceramic cross-dating, and Bayesian modeling of AMS dates from the southern periphery of the site. These data generally support the chronology developed by Gareth Lowe following the 1960s excavations at the site, though a temporal overlap appears possible for the Terminal Formative Hato and Itstapa ceramic complexes. Although results do not support Inomata and colleagues’ proposal for a shift in the Izapa chronology, ceramic cross-ties proposed between the Hato phase at Izapa and the Verbena phase at Kaminaljuyu support Inomata and colleagues’ (2014) revision for the chronology of Kaminaljuyu.

To study the Classic Maya is to at once recognize the shared material representations and practices that give coherence to this cultural category as a unit of analysis, as well as to critically examine the diversity and idiosyncrasy of specific cultural traits within prehispanic Maya society. Maya hieroglyphic writing, in particular the tradition of inscribing texts and images on carved stone monuments, offers evidence for widespread and mutually intelligible cultural practices that were, at the same time, neither unchanging nor uniform in their semantic content. As conduits of linguistic and cultural information, Maya hieroglyphic monuments offer detailed records of Classic Maya dynastic history that include the names, dates, and specific rituals performed by élite individuals. In this article, we analyze the distribution and diversity of these inscriptions to examine ritual variation and the divergence of dynastic traditions in Classic Maya society. Diversity indices and methods adapted from population genetics and ecology are applied to quantify the degree of ritual differentiation and evaluate how these measures vary over time and are partitioned within and between elite populations. Results of this research refine our understanding about the variation of Clássic Maya ritual traditions and make substantive contributions to examining the population structure of cultural diversity within past complex societies.

This study places the recently excavated ninth-century A.D. four-part calendrical notations at Xultun (Lunar Table, Ring Number, Long Count, and Multiplication Table) in the context of both Classic monumental inscriptions and astronomical knowledge in the Postclassic Dresden Codex. We demonstrate that the Lunar Table employed a formula attributed to Palenque and that it could have been used as a device to determine precisely where to break the sequence of alternating 29- and 30-day months one finds on dated monuments. All four categories found at Xultun appear in the Dresden Codex. The Ring Number, which bridges a date in the deep past with one in the recently completed era, is a perfect fit with one of the most fundamental Dresden eclipse cycles. Our analysis of glyphs accompanying the Long Count date enables us to place candidate eclipses, especially one that corresponds with a conjunction of Mars, in real time. We argue that the large multiples were extracted from, or prepared for, warning tables like the Dresden eclipse table, and we demonstrate why such tables must have existed well before the Xultun inscriptions. Thus, while the writings in the Dresden manuscript constitute a finished product, the writing on the wall of residential Structure 10K-2 is more akin to what one might find in an astronomer's notebook.

Contemporary research on prehispanic Maya landscapes has focused on caves as core features of the cultural geography. Investigations within a number of large caves have suggested that they served as the loci for important rituals, legitimized inhabitants’ claims to their territory, and helped establish the authority of a site’s ruling elite. The ubiquity and centrality of caves in the Maya worldview raises questions about what happened in regions where large caves did not naturally form. Recent investigations at the site of Maax Na in northern Belize suggest that small caves, despite their diminutive size, still functioned to establish legitimacy and uphold power. The results serve to demonstrate the pervasive power of key ideological concepts in shaping the cultural landscape and indicate the need to take these into account in documenting landmarks at Maya sites, as even the less imposing ones may have been important to their inhabitants.

This report describes recent low-intensity archaeological investigations conducted at three small sites in the northern Basin of Mexico. The sites are represented by surface artifact scatters and are located on the former shoreline of the now-drained Lake Xaltocan, originally one of the principal lakes in this region. Fieldwork included mapping surface concentrations and site dimensions, conducting test excavations, and recovering surface collections. The analysis of surface artifacts focused on determining site function and chronology. Based on fieldwork and analysis, we propose that Michpilco likely was a habitation site with a substantial occupation during the Classic period. The smaller Non-Grid 5 site was occupied during the Epiclassic period, and site Non-Grid 6 was occupied during the Late Postclassic to colonial periods. These sites reflect occupations in a lacustrine landscape throughout different periods. They also exemplify the rapid disappearance and threat of destruction that looting, infrastructural development, and agriculture pose to archaeological sites in the region.

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.

In this study, we employ multiple lines of evidence to elucidate the use of mortuary ritual by the ruling elite at the ancient Maya site of Cahal Pech, Belize, during the Early Classic and early Late Classic periods (AD 250–630). The interments of multiple individuals in Burial 7 of Structure B1, the central structure of an Eastern Triadic Assemblage or “E-group” style architectural complex, were in a manner not consistent with the greater Belize River Valley, the only multiple individual human burial yet encountered at Cahal Pech. The sequential interments contained a suggestive quantity of high-quality artifacts, further setting them apart from their contemporaries. Among these artifacts were a set of bone rings and a hairpin inscribed with hieroglyphs, some of the few inscriptions ever found at Cahal Pech. We analyzed regional mortuary patterns, radiogenic strontium values, and radiocarbon data to test hypotheses about who these individuals were in life, why they were treated differently in death, and to reconstruct the sequence of events of this complex mortuary deposit. We contend that the mortuary practices in Burial 7 indicate an attempt by the Cahal Pech elite to identify with cities or regions outside the Belize River Valley area.
