We present an AMS radiocarbon date from a bird image in a cave on the island of Hispaniola in the northern Caribbean. Borbón Cave No. 1 contains a key rock art assemblage that likely reflects a significant part of past native Taíno societies’ symbolic thought and beliefs. The grouping has already served to define one rock art style in the Antilles: the Borbón School. Our sample yielded a date of 890 ± 30 BP (1045–1225 cal AD). This result, as well as additional published dates for the region, confirms that these images were created before European contact with the region. Further dating comparison indicates that Taíno artistic traditions persisted for some years after the arrival and settlement of Spanish colonists on the island.

Although direct evidence of civic planning is rare among Mesoamerican sites, such features offer great insight into past practices, intentions, and urban transformation. Using data from the transition to the Late Formative period (ca. 400–300 BC), I argue that direct evidence of urban planning is present in the monumental constructions of Yaxuná in Yucatán, Mexico. There, investigators detected a series of carefully rendered incised lines directly on Floor 6 of the E Group plaza. Along with the buildings' exposed surfaces, incised lines served as visual markers for placing rubble and dry-core fill into two categories: large dry-core stones and small compact fill. These visual distinctions informed the location of features built on top of this fill, including Floor 5 and a causeway spanning the plaza's central axis, distinguished from the white floor surface sascab (a durable product of pulverized limestone) by a red-orange color. The incised lines at Yaxuná grant insight into how ancient builders envisioned public works and then implemented and completed features in a step-by-step design process, which required precision and foresight.

In embedded economies where multiple modes of production and exchange exist, artifact distributions in households alone do not reflect the strength of specific modes. We use a diachronic perspective tied to changes in political economies and artifact class densities standardized by excavation volume at the Maya site of Actuncan, Belize, to elucidate changes in the strength of individual production and exchange modes in the Preclassic and Classic periods. We focus on ground stone densities as a measure of grinding intensity across elite and common households. Data indicate that common households always ground more maize than elites, but intensity peaked in the Late Classic when tax and tribute demands and market exchanges were greatest. In the Terminal Classic, common household grinding intensity decreased by half as tribute burdens diminished, illustrating the impact of political hierarchies on household economies.

En este trabajo presentamos un análisis zooarqueológico de las relaciones humano-camélido durante el Holoceno en la Puna de Atacama (norte de Chile y Noroeste argentino) a través del estudio de composiciones rupestres interpretadas como escenas de caza durante el lapso entre 9700 y 2500 aP. Estas representaciones aluden a interacciones sociales y a un imaginario visual que vincula humanos y camélidos en un mismo acontecimiento. Planteamos que el estudio de estas manifestaciones pintadas puede aportar evidencia sustancial sobre las características de la caza comunal, la demografía de los cazadores recolectores y los primeros pastores del área surandina. Así, hemos podido identificar con el análisis del arte rupestre, tanto eventos de caza llevada a cabo por grupos locales, como así también cazas colectivas o comunales efectuadas por grupos agregados de población dentro de un ciclo anual o de agregaciones poblacionales extraordinarias. Esto representa un cálculo demográfico efectuado por primera vez a partir de las escenas de caza del arte rupestre.

En la subcuenca de Magdalena en el estado de Jalisco, los pueblos asentados en las inmediaciones del lago aprovecharon los recursos disponibles para la producción artesanal de bienes útiles y suntuarios. La presencia del Volcán de Tequila, el Lago de Magdalena y el sistema Lerma-Chapala-Santiago, facilitaron el acceso a recursos y la movilidad de productos para su distribución. En el centro del cuerpo acuífero fósil se eleva Atitlán, isla que resguarda evidencia de actividades de producción que se relacionaron con el aprovechamiento de recursos minerales y acuáticos por lo menos a partir del año 450 dC y hasta el 1500 dC. Dentro de las evidencias estudiadas sistemáticamente a nivel de superficie, es de nuestro interés una acumulación de objetos de obsidiana que se extiende en un área de 56.400 m2. El análisis espacial de distribución, junto con los de morfología, desgaste y microscopía aplicada a la identificación de huellas de uso, nos permiten explicar que se trató de un espacio de producción especializado de instrumentos de obsidiana mediante la técnica de talla, los cuales fueron empleados para el aprovechamiento de recursos perecederos.

People from different areas of the insular Caribbean and the coastal zone of mainland South America moved in and out of the Lesser Antilles throughout the archipelago's history before the European invasion. Successive migrations, the development of networks of human mobility, and the exchange of goods and ideas, as well as constantly shifting inter-insular alliances, created diverse ethnic and cultural communities in these small islands. We argue that these processes of alliance-building and ethnicity can be best understood through the concept of creolization. We examine this idea first in terms of the cultural interactions reflected in the pottery traditions that emerged among the Windward Islands before colonization, and second by analyzing the historiographical and emerging archaeological information available on the formation of the Indigenous Kalinago/Kalipuna and Garifuna identities from the late fifteenth to the early seventeenth centuries. Finally, we discuss the colonial and contemporary Afro-Caribbean pottery traditions on these islands, in particular Grenada and Saint Lucia. The embedding of this study in a deep historical framework serves to underscore the divergent origins and developmental trajectories of the region. including the disruption of the Indigenous cultures and the impact of European colonization, the African diaspora, and the emergence of today's cosmopolitan Caribbean cultural tradition.

Este artículo, el primero de una serie de dos, analiza la investigación actual sobre el acoso en la arqueología que ha dado forma a la disciplina desde finales de 1800. A partir de la década de 1970, el acoso se reconoce como un factor significativo que afecta la equidad de género. Investigaciones cualitativas y cuantitativas recientes han verificado que el acoso ocurre a tasas epidémicas, en tanto les arqueólogues son acosades, principalmente por otres arqueólogues, y esto ocurre no sólo en entornos de investigación de campo, sino también en aulas, laboratorios, museos, lugares de trabajo y conferencias. Aunque las mujeres en la arqueología experimentan acoso con mayor frecuencia, las cifras de hombres como de mujeres informan de acoso en proporciones inquietantemente altas. Les arqueólogues de color, LGBTQIA+, no binarios y con discapacidades también son hostigades de manera desproporcionada. Como se refleja en las propias experiencias de la autora, el acoso crea una carga cognitiva para les sobrevivientes y reduce el acceso a oportunidades profesionales, impactando directamente en la diversidad dentro de la arqueología. Afortunadamente, existen intervenciones y políticas basadas en evidencia que pueden reducir esta práctica y apoyar a les sobrevivientes, lo que se analiza en el segundo artículo, “Contra las culturas del acoso en la arqueología: Enfoques socioambientales y basados en el trauma para la transformación disciplinaria”.

Este artículo es el segundo de una serie de dos partes que analiza la investigación actual sobre el acoso en la arqueología. Estudios cualitativos y cuantitativos, como también relatos de activistas y testimonios de sobrevivientes, han establecido que el acoso ocurre a tasas epidémicas en la arqueología. Estos estudios han identificado patrones clave en relación al acoso y señalan posibles intervenciones para prevenirlo, para apoyar a les sobrevivientes y para responsabilizar a les perpetradores. Este artículo discute cinco obstáculos clave a superar en la cultura disciplinaria de la arqueología: normalización, prácticas excluyentes, confraternización, gatekeeping e impedimentos para la presentación de denuncias. Con base en dos paradigmas de salud pública —el modelo socioambiental y los enfoques basados en el trauma— se identifican intervenciones potenciales aplicables a todos los niveles de la práctica arqueológica: individual, relacional, organizacional, comunitario y social.

The virtual removal of forest canopies through light detection and ranging (lidar) has enhanced archaeological interpretations of settlement patterns in tropical zones. Although lidar collections of Indigenous landscapes in the Caribbean Archipelago are limited, resolutions from open-access lidar datasets reveal coarse regional settlement patterns and large-scale architecture planning. In this article we inspect the Caguana Ceremonial complex in Utuado, Borikén (Puerto Rico), using a 2016 lidar dataset available through the National Oceanic and Atmospheric Administration portal. Visual comparisons between known Indigenous sites, surface anomalies, and site inspections in the three sectors under study identified plazas, possible ancient paths into the Caguana complex, a possible agricultural area west of the site, and the ANG-4 site. This study, the first application of lidar inspections in Puerto Rican archaeology, demonstrates that open-access data can help guide research and save time in field surveys, thus improving our ability to protect the Indigenous cultural heritage hidden under forest canopies.

This study examines the ritual and socioeconomic significance of animals in ceremonial contexts at Kaminaljuyu, Guatemala. Kaminaljuyu was once the largest and most politically powerful highland Maya center. We compare faunal remains from different contexts, including burials and dedicatory offerings in and around monumental features, to better understand the role of animals in these deposits. We then compare ceremonial activities across Mesoamerica to identify similarities alluding to widely recognized practices. Late and Terminal Preclassic (350 BC–AD 250) ceremonies at Kaminaljuyu contain some of the earliest marine fish recovered from a Maya highland site, demonstrating the ability of early elites to obtain exotic species for special events. Dogs, including perhaps the first evidence for Preclassic hairless dogs in Guatemala, appear in deposits that resemble canine sacrificial offerings in central Mexico. The new faunal data in this study provide a novel perspective on Kaminaljuyu's sociopolitical role in the region.

Archaic projectile points from the Andean Altiplano exhibit a curious trend of increasing size over time, in contrast to a well-documented size reduction throughout North America. Although a number of hypotheses exist to account for decreasing projectile-point size, there are currently no explicit explanations for increasing size. We consider several hypotheses and interrogate two techno-economic hypotheses. We posit that increasing point size compensated for lost dart momentum or accuracy that resulted from the shortening of atlatls or atlatl darts as wood became increasingly scarce on the tree-sparse Altiplano. We evaluate these hypotheses using a replicated Andean atlatl system in ballistic trials. Contrary to expectation, results show that point enlargement significantly reduces penetration depth, allowing us to confidently reject the momentum hypothesis. Point enlargement, in contrast, tentatively correlates positively with accuracy. Our experiment further shows that camelid bone is an effective and economical alternative to wood for atlatl production. Despite suboptimal lengths, camelid radioulna atlatls have a convenient morphology that requires low production time, which helps explain empirically observed camelid bone atlatls from the Andean highlands. More generally, our observations lead us to consider that central tendencies in archaeologically observed projectile-point size may reflect a trade-off between penetration and accuracy.

Aquí presentamos el descubrimiento de una banca jeroglífica esculpida del sitio maya de Ixtutz, Petén, Guatemala. Analizamos la inscripción jeroglífica en la banca y discutimos la historia del objecto en el contexto de su producción, su desmantelamiento y reutilización subsecuente, y la remoción de unas piezas del sitio. Mostramos que dos bloques inscritos de caliza, uno de ellos en una colección privada en Bruselas y el otro en el Los Angeles County Museum of Art, Los Angeles, California, pertenecen al mismo trono, y llamamos para su repatriación voluntaria a Guatemala.

Archaeologists have used isotope analysis (δ13C, δ15N) of the collagen of human bones, as well as knowledge of available nutrients, to infer that the diet of the ancient Maya was drawn from the resources of the Maya forest landscape. The interpretations have focused on plant carbohydrates from maize and protein dominated by white-tail deer. The δ15N values of bone collagen suggest that most of the protein requirements of the Maya could have been satisfied with a mixture of wild animal flesh and wild and cultivated plants including beans. Chaya, Cnidoscolus aconitifolius, domesticated before the Spanish conquest, has a high-protein content and the potential to have been a significant contributor to the ancient Maya diet. Chaya is easily propagated, is grown in home gardens by the Maya today, and is a significant part of the local traditional diet. Chaya's stable isotopic composition of carbon (δ13C) resembles that of other terrestrial plants, but its values for nitrogen (δ15N) are significantly higher. Consumption of chaya would result in slightly higher δ15N values in humans than expected from the consumption of terrestrial animals. Thus, chaya is situated well as a component of the complex, diverse, and varied diets of ancient Mesoamericans.

Mutual toasting using pairs of intricately carved wooden cups, called queros, was the fundamental act incorporating local communities into the Inka Empire (AD 1400–1532). These cups then remained in the possession of provincial communities and were used to reaffirm political ties in subsequent state-sponsored events. I argue that the value of these cups derives from their inalienability: they were indelibly imbued with the power of the Inka state and were objects of memory embodying the history of local–imperial relationships. Archaeologically, queros are often found in mortuary contexts, usually as pairs. This suggests that these vessels functioned to authenticate claims to authority vis-à-vis the empire for an individual or kin group. Less frequently, queros are deposited singly and in ritualized non-mortuary contexts. I review archaeological examples and present two new queros from the site of Moqi (Upper Locumba Valley, southern Peru). At Moqi, these queros were used not only to promote a shared affinity with the empire but also to commemorate the sundering of the community's ties to the Inka state on abandonment of the site. Such community expression, at the expense of personal aggrandizement, may have been particularly important at Moqi and other sites constructed and populated de novo by the Inka.

Camelid pastoralism, agriculture, sedentism, surplus production, increasing cultural complexity, and interregional interaction during northern Chile's Late Formative period (AD 100–400) are seen in the flow of goods and people over expanses of desert. Consolidating evidence of material culture from these interactions with a bioarchaeological dimension allows us to provide details about individual lives and patterns in the Late Formative more generally. Here, we integrate a variety of skeletal, chemical, and archaeological data to explore the life and death of a small child (Calate-3N.7). By taking a multiscalar approach, we present a narrative that considers not only the varied materiality that accompanies this child but also what the child's life experience was and how this reflects and shapes our understanding of the Late Formative period in northern Chile. This evidence hints at the profound mobility of their youth. The complex mortuary context reflects numerous interactions and long-distance relationships. Ultimately, the evidence speaks to deep social relations between two coastal groups, the Atacameños and Tarapaqueños. Considering this suite of data, we can see a child whose life was spent moving through desert routes and perhaps also glimpse the construction of intercultural identity in the Formative period.

This study investigates the impact of the Aztec Triple Alliance on trade and economic activity in the region of Puebla-Tlaxcala during the Late Postclassic period (AD 1200–1519). Ethnohistorical sources describe the Aztec Triple Alliance as constantly at war with settlements in the Tlaxcala region. To weaken their Tlaxcalteca rivals, the Aztecs imposed a trade blockade to reduce the flow of resources into Puebla-Tlaxcala. This article uses archaeological evidence to evaluate the effectiveness of this blockade. It compares the types of obsidian used to manufacture lithic tools from Aztec-controlled sources with those used within Puebla-Tlaxcala. Information from the large center of Tepeticpac and the small obsidian workshop site of Cinco Santos II, both in the Tlaxcala domain, are compared to other sites in Central Mexico prior to and during the height of Aztec influence. The results show little difference in regional trade patterns: obsidian from Sierra de las Navajas and Otumba was used in proportions in the Tlaxcala region in the Late Postclassic similar to those used during earlier periods. If an embargo was attempted, it was largely unsuccessful in isolating Tlaxcala from broader regional distribution networks.

Archaic period hunter-gatherers of the Lower Pecos Canyonlands of southwest Texas and Coahuila, Mexico, created complex rock art murals containing elaborately painted anthropomorphic and zoomorphic figures. These figures are frequently portrayed with dots or lines emanating out of or into their open mouths. In this article, we discuss patterns in shape, color, and arrangement of this pictographic element and propose that artists used this graphic device to denote speech, breath, and the soul. They communicated meaning through the image-making process, alternating brushstroke direction to indicate inhalation versus exhalation or using different paint application techniques to reflect measured versus forceful speech. The choices made by artists in the production of the imagery reflect their cosmology and the framework of ideas and beliefs through which they interpreted and interacted with the world. Bridging the iconographic data with ethnohistoric and ethnographic texts from Mesoamerica, we suggest that speech and breath expressed in the rock art of the Lower Pecos was tied to concepts of the soul, creation, and human origins.

Investigations at sites across northwestern Honduras—inside and outside the Maya area—have revealed diverse food activities and ingredients. Paralleling the evidence from durable artifact assemblages, we see transformation over time in materials and practices, as well as the movement of elements across the landscape. Botanical evidence points toward a dynamic overlap between northern and southern societies, with northwestern Honduras serving as a sort of regional crossroads. In this article, we compare cuisines from several ancient communities in northwestern Honduras, using microbotanical and macrobotanical residues. We briefly address the political and historic context of the region and provide abridged biographies of several culinary taxa. Of particular interest are milpa annual crops such as maize and squash, managed and cultivated palm species, wild and managed herbaceous species, edible fruit species, and root and tuberous crops such as lerén, sweet potato, and manioc.

Coastal–highland relationships were important in the development, expansion, and collapse of ancient societies in Nasca, Peru. Connections between the regions began with the earliest occupants and extended through Inca rule; they consisted of the exchange of goods, sharing of ideas, migration, and political dominance. By the end of the Early Intermediate period (Late Nasca, AD 500–650), highland relationships intensified, and during the Middle Horizon (AD 650–1000), Nasca for the first time came under highland control as the Wari Empire brought transformations to the region. By the end of the Middle Horizon, Wari had collapsed, and much of the Nasca drainage was abandoned. People emigrated from the region, probably because of drought coupled with political and social instability. When Nasca was repopulated (ca. AD 1200) in the Late Intermediate period, a new type of society developed that was likely the result of large numbers of highland immigrants.
