A common property regime was established at the founding of the Maya site of Actuncan, Belize, in the Terminal Preclassic period (175 BC–AD 300), which governed access to land until the Terminal Classic period (AD 780–1000). This interpretation is based on urban settlement patterns documented through household excavation and remote-sensing programs. Excavations of all visible patio-focused groups in the urban core provided data to reconstruct residential histories, and a 60,621 m2 gradiometer survey resulted in a magnetic gradient map that was used to document buried constructions. Twenty ground-truth testpits correlated types of magnetic signatures to buried patio-focused groups and smaller constructions, including walled plots in agricultural field systems that were later exposed more fully through large-scale excavations. Combined, these methods provided data to reconstruct four correlates of land tenure systems: (1) the spatial proximity of residential units to land and resources, (2) diachronic changes in community settlement patterns, (3) land subdivision and improvements, and (4) public goods. Spatial analyses documented that houselots did not cluster through time, but instead became gradually improved, lending evidence to suggest the transgenerational inheritance of property rights in the Late and Terminal Classic periods.

Several khipus—Inka knotted-string recording devices—were recently excavated at a storage facility at the Peruvian south coast site of Inkawasi, found buried under agricultural produce (i.e., chili peppers, peanuts, and black beans). These khipus contain a formulaic arrangement of numerical values not encountered on khipus from elsewhere in Tawantinsuyu (the Inka Empire). The formula includes first, a large number, hypothesized to record the sum total of produce included in a deposit, followed by a “fixed number,” and then one or more additional numbers. The fixed number plus the additional number(s) sum to the original large number. It is hypothesized that the fixed number represents an amount deducted from the deposit to support storage facility personnel. As such, it represented a tax assessed on deposits, the first evidence we have for a system of taxation on goods in the Inka Empire. It is proposed that the size and complexity of the storage facility at Inkawasi prompted the “invention” of a kind of financing instrument—taxation—not known previously from Inka administration. We also consider, but provisionally set aside, the alternative hypothesis that the fixed values recorded on the Inkawasi khipus could have represented amounts of seeds set aside from deposits for the next year's planting.

En las sociedades andinas actuales las relaciones de parentesco determinan el tipo de matrimonio y el patrón de residencia posmarital que garantizan el manejo de los recursos, la supervivencia y la estabilidad reproductiva de la población. Sin embargo, es escasa la información disponible en el Área Andina Centro-Sur (AACS) para explicar los sistemas de parentesco durante el poblamiento original del territorio y su impacto en la estructura de las poblaciones locales posteriores a la conquista y colonización europea. En el presente trabajo se investiga el patrón residencial en dos sectores del AACS a partir de datos bioarqueológicos disponibles para el Noroeste Argentino y Norte de Chile. La información necesaria pudo ser recuperada a partir de la arqueología y de la antropología física regional. La muestra proviene de 8 localidades y 44 sitios con fechados que cubren el intervalo cronológico desde 3000 aC hasta 1450 dC, desde grupos arcaicos tempranos hasta comunidades agroalfareras tardías. Se emplearon 1.897 observaciones y 27 variables craneométricas. El análisis se realizó con técnicas estadísticas multivariadas: el cálculo de la varianza generalizada (determinante de la matriz de varianzas y covarianzas) para cada sexo y la estimación de los estadísticos de distancia (D2) y divergencia fenotípica (Fst) entre grupos y sexos. Los resultados revelan el efecto de distintos flujos migratorios que determinaron la estructura de las poblaciones. En todos los casos la varianza generalizada masculina es mayor que la femenina indicando una mayor variabilidad entre sitios y una mayor actividad migratoria. Los valores de D2 y Fst femeninos son mayores entre regiones y localidades con una menor tasa migratoria. Estos resultados indican, en general, la prevalencia de una estrategia de supervivencia basada en un sistema de parentesco que favoreció un modelo de residencia matrilocal.

Classic Maya “killed” objects. They broke and dispersed ceramic vessels. After adding exotic artifacts, they burned everything, buried the deposit with marl, and tore down associated rooms or buildings. This complex set of interrelated activities has been classified as a termination ritual. Instead of accepting this as a natural category, we study how the Classic Maya strategically differentiated some practices from others. Our case study are the deposits in Structure 5PS-12, an eighth-century AD building at the outskirts of the royal capital of Tamarindito, Guatemala. Destroyed wall foundations and evenly distributed wall fall indicate that Structure 5PS-12 was dismantled. Complete tools and exotic artifacts are found within the wall fall and on the floor. Refitted ceramic sherds show that partial vessels were broken apart and scattered across the building. The combination and sequence of these practices reveal a deliberate strategy to distinguish some practices from others. Its practitioners may have witnessed a fire ceremony conducted by the divine rulers of Tamarindito in AD 762. Structure 5PS-12 attests to shared and possibly copied ritual procedures, whereas unique practices establish a local way of abandonment. The process of differentiation allows people to display but also question shared cultural frameworks. The Maya ritualized practices in a social discourse about appropriate norms and behaviors.

This paper uses plane pattern symmetries to describe the structural arrangement of motifs in Sikyatki-style patterns on textiles depicted in fourteenth and fifteenth century AD kiva murals from Awat'ovi and Kawaika'a in Arizona and Pottery Mound in New Mexico. The analysis reveals that these textiles have pattern structures in common with designs on textiles, ceramic artifacts, and architectural decorations in the Postclassic Mixteca-Puebla style. These shared patterns and pattern structures were introduced into the American Southwest woven on fabric structures of textiles brought north from Mesoamerica via trade and migration routes along the Mexican West Coast and through the Sierra Madre.

Este trabajo busca profundizar el conocimiento sobre el rol de los sectores intermedios de las quebradas en el entramado social de la microrregión de Antofagasta de la Sierra (Puna meridional argentina) a lo largo del tiempo. A través del estudio de la tecnología cerámica desde una perspectiva diacrónica (ca. 2000-500 aP), haciendo énfasis en los estudios petrográficos de pastas, se investigan los cambios y continuidades en la producción alfarera de la microrregión. Para ello, se presentan los resultados de la investigación realizada sobre el material cerámico proveniente de los sitios de Las Escondidas y Corral Alto, en la quebrada del Río Miriguaca, y Cueva Salamanca 1, en la quebrada del Río Las Pitas. A partir de los análisis realizados, se pudo concluir que existieron cambios en los modos de hacer cerámica a lo largo del tiempo en la microrregión. Se observó que durante el Formativo (ca. 2000 aP) existió un modo de hacer compartido en un área amplia, mientras que durante el periodo Tardío (ca. 800 aP) se dio una fragmentación en las prácticas de producción cerámica en la microrregión. Estos cambios responden a profundas trasformaciones ocurridas en las sociedades puneñas que se comenzaron a gestar tiempo antes del comienzo del período Tardío en un proceso paulatino, complejo y heterogéneo.

Shared identities create deep historical ties to community spaces and can facilitate or constrict political expansion. This research examines the relationship between the ways in which families engaged local landscapes and developed shared identities at Actuncan, Belize, during the Terminal Classic period, a time when the city experienced population growth as surrounding centers declined. The nature and location of activity patterns in and around three residential groups allow inferences about shared practices and the expression of identities that those activities enabled and constrained. Importantly, this research includes investigations of both residential groups and architecturally free areas. It uses multiple methods to explore activities and to produce overlapping datasets, including excavation and analysis of macroartifacts, microartifacts, and soil chemical residues. The results suggest that Actuncan residents used not only the formal patio spaces of residential groups but also the interstitial spaces between them. Moreover, one residential group, Group 1, appears to have been a locus for distinct activities including sequential burials and, possibly, affiliative ritual practices connected to ancestral landscape use. Understanding relationships among residents is an important foundation for exploring broader political dynamics, including relationships between residents and rulers and how rulers created, legitimized, and maintained power and authority.

Early occupation at Nixtun-Ch'ich’, on the western edge of Lake Petén Itzá, is dated by two ceramic complexes, K'as and Chich. These represent the Late and Terminal Early Preclassic or the early and late “Pre-Mamom” periods, respectively (ca. 1300–800 BC), including a “Transitional” period incorporating Nix Middle Preclassic (Mamom) pottery. Comparisons with complexes at other sites in the region permit the dating of 10 construction loci, including 3 in the civic-ceremonial core. Low late Pre-Mamom platforms were raised and expanded in Transitional and Early Middle Preclassic times, when they were elaborated into two E-Groups and a Triadic Structure on the central axis. This building activity is interpreted in terms of cooperative or corporate labor organization and related to evolutionary game theory. The ritual foundation of such organization is evident in the site's gridded layout based on a mythical world-creation crocodile.

Material culture studies demonstrate how objects may act to communicate information regarding social identity. In this study we consider ethnohistorical, ethnographic, and archaeological evidence for Postclassic spinning and weaving as symbols relating to female ideology in ancient Mexico. We then relate a contextual interpretation of texts and images to contemporary symbolism, particularly associated with members of the female earth/fertility deity complex depicted and described in precolumbian and early colonial pictorial manuscripts. For our case study we analyze decorative imagery found on baked-clay spindle whorls from Postclassic Cholula, Mexico. This collection is representative of an iconographic system relating to female ideology. Whorls, as well as other spinning and weaving tools, paralleled male-oriented weapons to create a symbolic equivalence or, as we argue, a usurpation of the male symbols within a female worldview as a form of resistance to male domination. We conclude that the symbolic system used on spindle whorls and in other aspects of female practice created a communication network understood by Postclassic women.

Este artículo discute las evidencias de violencia perimortem y las relaciones espaciales de partes esqueletales recuperadas en la Estructura Funeraria 4 del sector I del sitio de Punta de la Peña 9 (Antofagasta de la Sierra, Catamarca, Argentina). Esta estructura, que contiene varios individuos correspondientes a la segunda mitad del primer milenio dC, presenta evidencias de haber sido reabierta en al menos dos eventos de inhumación, lo que produjo alteraciones de los patrones mortuorios y desarticulación de partes anatómicas. Estas reaperturas se relacionan con una dinámica particular de las prácticas de entierro en Antofagasta de la Sierra. Se trata del primer entierro secundario múltiple identificado para el área, el cual incluye a su vez los primeros casos de trauma intencional y muerte en condiciones violentas. Se inhumaron al menos siete individuos de ambos sexos y de distintos rangos de edad, cuatro de los cuales presentan lesiones perimortem en los cráneos, evidencia directa de situaciones de violencia interpersonal para los grupos agropastoriles de este período.

Este artigo apresenta um processo de ocupação de grupos construtores de cerritos no sítio arqueológico Pontal da Barra, localizado no estuário da Laguna dos Patos, sul do Brasil. Ocupado entre 2500 e 1800 anos aP como área de acampamentos e, posteriormente, entre 1800 e 1200 anos aP como área de ocupação permanente, o Pontal da Barra foi abandonado por volta de 1000 anos aP. Esse processo é evidenciado arqueologicamente pela complexificação de estruturas arquitetônicas monticulares e suas áreas adjacentes, pelo manejo de sedimento interno nos montículos, além dos aspectos multifuncionais e monumentais dos aterros. Como parte de um território regional, o banhado do Pontal da Barra se tornou um espaço significativo no domínio espacial dos grupos cerriteiros. O sítio foi sistematicamente ocupado ao longo de 1.500 anos, compondo uma comunidade de pescadores, agentes de uma história indígena de longa duração.

The marine subsistence economy of the prehistoric people of northern Chile was heavily reliant on fiber technology for the components of nets, lines, and tethers. Despite the significance and the remarkable preservation of fiber artifacts along the arid Atacama coastline, these components have received little direct attention. This case study of fiber artifacts from the Caleta Vitor archaeological complex is the first broad overview of techniques, material usage/preference, and fiber-processing conventions at a northern Chilean Archaic period site. The data presented in this paper indicate gradual change in material preferences over time, shifting from locally available vegetal fiber, which dominates the Archaic period, with small amounts of camelid fiber, to the predominance of camelid fiber in the Late Formative period. This change coincides with the appearance of more complex weaving techniques indicating participation in the previously established textile tradition proposed by Ulloa (2008) as stretching from the Azapa Valley to the Loa River.

The site of Tipon, Peru, located about 30 km east of Cuzco, provides an example of Inka knowledge of hydraulic engineering and the civil engineering practices used in the design and operation of the complex water system. The inhabitants of Tipon used river- and spring-sourced surface and subterranean channels to convey, distribute, and drain water to and from multiple agricultural platforms, reservoirs, and urban ceremonial centers. Intricate intersecting surface and subterranean channel systems that combined and regulated water flows from different sources controlled the water to and drainage from 13 terraced agricultural platforms. This design served to maintain different ground moisture levels to sustain specialty crops. Within the site are fountains and multiple water display features requiring sophisticated hydraulic engineering necessary for aesthetic displays. To understand the technology used by the Inka to design the water systems at Tipon, I used computational fluid dynamics methodology and modern hydraulic engineering theory. I made computer models of key elements of the Principal Fountain and the Main Aqueduct to reproduce water flow patterns in these features as intended by Inka engineers’ designs and calculations. The Inka hydraulic technology used complex engineering principles similar to those in modern civil engineering practice centuries ahead of their formal discovery in Western hydraulic science.

Shrines were a regular component of ceremonial architecture in the public plazas of Postclassic Maya centers. Small shrines and natural landmarks such as caves and outcrops at the borders of settlements or in wilderness locations also served, and in some cases continue to serve, as important ritual loci for Maya peoples. These more peripheral locales were not only critical access points to the supernatural, but also served to delineate places. Because these border features, which represent only a given moment in a constantly shifting social and political landscape, are sometimes unmodified or are inconspicuous, they are relatively ephemeral and difficult to identify in the archaeological record. This paper documents a Late Postclassic shrine paired with a natural feature, a small hill, from the site of Tayasal in Petén, Guatemala. We argue that it served as a border shrine. Paired with the small hill, the two embodied a liminal frontier, not only between earthly and spiritual realms but also between settled and unsettled space.

The morphological study of architectural features, the building arrangement within urban spaces, and multiscalar variation are critical for understanding urbanism as a process. Building types and architectural typologies form the foundational blocks of urban morphology and are essential for identifying architectural patterning. We use a process-typological approach to present an architectural typology from the ancient Purépecha (Tarascan) city of Angamuco, located in the Lake Pátzcuaro Basin, Michoacán, Mexico. Using archaeological survey, lidar analysis, and excavation, we analyze building foundations from houses and public structures; storage facilities; monumental architecture such as pyramids, altars, and public buildings; and landscape features such as plazas, roads, terraces, and raised roadways locally known as huatziri. Our typology enhances understanding of the dense urban environment of this important prehispanic city during and after the formation of the Purépecha Empire.

Tradicionalmente, el efecto combinado de la demografía y la productividad de los ambientes patagónicos ha sido invocado para explicar que el interior del bosque del centro-norte de la Patagonia argentina fue utilizado luego de la ocupación de espacios más favorables, con una antigüedad máxima de 3.500 años. El hallazgo de contextos del Holoceno temprano y medio en el sitio de Población Anticura situado en el bosque mixto permite reformular este escenario. El análisis sedimentario, de los procesos de formación y de la evidencia arqueológica recuperada indica, para estos momentos, la existencia de ocupaciones breves y con cierta redundancia a través del tiempo, con conjuntos artefactuales pequeños pero variados, una subsistencia basada en el huemul (Hippocamelus bisulcus) y el consumo ocasional de especies de menor tamaño corporal como alimento y como materia prima. La procedencia de algunos materiales sugiere que el uso temprano del interior del bosque estaría vinculado a redes de circulación amplias en el marco de una baja demografía, mientras que la naturaleza de las ocupaciones muestra un conocimiento del ambiente que señala que los contextos más antiguos de Población Anticura no reflejan la primera exploración del interior del bosque.

Teotihuacan underwent an urban renewal during the Tlamimilolpa phase (AD 250–350) in which more than 2,000 apartment compounds were constructed to accommodate its estimated 100,000 residents. Although the orderly layout and canonical orientation of the city imply top-down planning, growing evidence suggests a bottom-up process of urban transformation. This study combines architectural energetics with archaeometric analysis of nonlocal construction materials (lime plaster and andesitic cut stone blocks) to examine the labor organization behind the construction of the apartment compounds. The results of the energetic analysis suggest that residents relied on labor forces external to their compounds, whereas materials analysis indicates that the procurement, transportation, and production of building material were centrally organized and thus indicative of a state labor tax. Based on these results, I argue that compounds were assembled through corporate group labor exchange or communal (neighborhood-level) labor cooperation/obligation, with differing degrees of support from the state labor tax. Apartment compound construction was not uniform but rather a diverse process in which state labor mobilization, communal labor obligations, and corporate labor exchange were articulated in various ways.

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.

As in other examples of state collapse, political disintegration of the Tiwanaku state circa AD 1000 was accompanied by considerable cultural continuity. In the Moquegua Valley, Peru, the location of the largest Tiwanaku communities outside the altiplano, settlements and practices associated with this postcollapse cultural continuity are termed Tumilaca. Previous research indicated that Tumilaca was short-lived, with all vestiges of Tiwanaku gone from Moquegua's archaeological record by the thirteenth century when the valley was subsequently characterized by Estuquiña-style materials. This article discusses radiocarbon dates from Tumilaca la Chimba, a village established as the political authority of the Tiwanaku state waned. The 21 absolute dates from Tumilaca domestic, public, and funerary contexts span at least 350 years, from the late tenth to the mid-fourteenth centuries AD. They suggest that (1) Tiwanaku-affiliated communities endured well into the later Late Intermediate Period (AD 1200–1470); (2) ongoing debates about the emergence of Estuquiña communities must consider the role of terminal Tiwanaku populations; and (3) analyses of postcollapse continuity can be enhanced by considering peripheral locales and the particularities of continuity.

Las prácticas alfareras en perspectiva arqueológica pueden ser estudiadas abordando diferentes aristas concernientes al proceso de producción y los restos materiales asociados a cada etapa. En este trabajo se presentan los resultados obtenidos del análisis tecnológico integral de una muestra extensiva de alfarería procedente del tambo Incaico de Costa de Reyes N°5 (Tinogasta, Catamarca, Argentina). La metodología implementada para lograr los objetivos consiste en la reconstrucción de formas típicas, la observación de cortes frescos en lupa binocular y la petrografía en secciones delgadas, aplicadas a un conjunto alfarero recolectado tanto de contextos superficiales como de excavaciones estratigráficas realizadas en dos recintos del sitio de Costa de Reyes N°5. A través de esta aproximación se han logrado visualizar continuidades y rupturas en el proceso de producción de alfarería y en las recetas aplicadas por los alfareros durante momentos de los períodos Agroalfarero tardío (ca. 900–1450 dC) e Inca (ca. 1480–1532 dC). Mientras que la producción de alfarería durante el período Tardío presenta características heterogéneas y una mayor variabilidad, en momentos Incaicos se observa que las recetas aplicadas por los alfareros para elaborar las pastas cerámicas se homogenizan, lo que se interpreta como un control más estricto sobre las fuentes de materia prima y sobre el proceso de hacer alfarería como un todo.
