The author's earlier thoughts about Mesoamerican and Peruvian horizon styles and regional stylistic diversity have been given new meaning by the concepts of “corporate” and “exclusionary” states as these have been formulated by R. E. Blanton and colleagues. Their synthesis should open the way for further dialogue concerning the processes of state formation as these can be observed in the archaeological record.

Archaeologists have long celebrated their unique ability to deal with the long term. But we are increasingly recognizing that we can and must also understand more rapid events. They are critical for many of the questions we now consider most interesting, such as distinguishing between changes that unfolded gradually and those that happened suddenly. In considering interactions among regions, we need something better than cross-dating on the basis of resemblances in material objects. That is especially so when we would like to know where something first developed and the tempo of its spread to other regions. As one particularly clear example of the beneficial effects of finer chronologies, Robert Santley (in Sanders et al. 1979:65-73) showed how shorter phases can drastically alter our picture of the ebb and flow of settlement history in a region. When Basin of Mexico sites in the Cuauhtitlan region are dated only in broad terms to the Middle and Late Formative periods, a rather placid picture of settlement change emerges.

El análisis del patrón de asentamiento en sociedades no jerárquicas tiene un gran potencial para abordar su variabilidad, en la medida que sus niveles de integración tienen una expresión física en los espacios corresidenciales y en la distancia entre ellos. A partir de una prospección intensiva en la microrregión de Angostura, Chile central, se compara la organización espacial de los asentamientos habitacionales de los periodos alfareros del área. Se trabajó con el tamaño y densidad de los 19 sitios detectados en el área, así como su distribución espacial. Se los delimitó por medio de redes de pozos de sondeo, a partir de cuya densidad se estimó la extensión y estructura de los sitios. La asignación cronocultural se realizó a partir de la clasificación del material alfarero y por 150 fechados por termoluminiscencia. La comparación indica que los periodos Alfarero temprano e Intermedio tardío presentan tanto similitudes como diferencias. En ambos momentos el patrón de asentamiento es disperso y la principal diferencia radica en la estructura interna de los sitios. Los asentamientos del Intermedio tardío tienen una menor cantidad de concentraciones y la densidad tiende a ser mayor, lo que sugiere que la composición de las unidades residenciales es distinta, estando compuestas por un mayor número de personas en el momento más tardío.

We studied the temporal and spatial variation of diet and oral health of human populations that inhabited the central region of Argentina during the Late Holocene (4000–300 BP) by evaluating isotopic data (δ13Ccol, δ15N), physiological stress indicators (tooth wear), and infectious dental diseases (caries). The sample of 49 individuals was recovered from archaeological sites located in the province of Córdoba, dated by AMS on collagen to a range of 4058 ± 89 years BP to 370 ± 15 14C years BP. After calculating the prevalence of caries and the average dental wear, we compared these values based on regional origin (central highlands and eastern lowlands), temporal assignation (early Late Holocene, late Late Holocene), and sex (female and male). We found clear regional and temporal differentiation, which we interpret as resulting from differential use of plant resources among the regions and a slight deterioration in oral health in the Late Holocene. Stable isotope analysis indicates food consumption of C3 and C4 resources, although the observed temporal variations in the isotopic values may indicate an introduction of C4 resources in the later Late Holocene, mainly in the mountainous region.

The site of Yaxchilán (Chiapas, Mexico) is one of the best-known Classic Maya cities, despite relatively little stratigraphic excavation. The dynastic history of the site is recorded in numerous legible inscriptions and was worked out more than 30 years ago by Tatiana Proskouriakoff (1963, 1964) in her epoch-making historical interpretations. A historical puzzle left by Proskouriakoff and later investigators is a 10-year gap (A.D. 742-752) between the death of a Late Classic king, Shield Jaguar II, and the accession of his successor and son, Bird Jaguar IV. Various explanations have been offered for this interregnum, often suggesting a rival heir to the throne, as Bird Jaguar was the son of his father's late, secondary, foreign wife. Nevertheless, no evidence has been put forth concerning a child by the king and his earlier, primary wife, a woman known as Lady Xok. This paper reexamines the epigraphic evidence by applying what is now known about Classic Maya grammar and the canons of Classic Maya literature to an inscription on the house of Lady Xok. Viewed from this perspective, a well-known inscription yields the name of the missing heir, and other evidence suggests the nature of his fate and the reason he did not take the throne.

Debates over the cultural and biological origins of some indigenous groups in the Americas have fueled discussions about cultural identity, political justice, and resource rights. A historically high-profile case of rights and origins has involved the Araucanians or Mapuche of the southern cone of South America. This article examines, for the first time, the recent interdisciplinary archaeological and other anthropological evidence for the Mapuche of Chile and Argentina. It suggests that the ethnic and territorial origin of the Mapuche is in central and south-central Chile, although biological and cultural influences from north Chile and western Argentina also are present. It briefly discusses the implication of this study in relation to the indigenous status of the Mapuche in present-day Chile and Argentina.

Horizontal excavations at the large Inka heartland village of Cheqoq (Maras, Cuzco, Peru) revealed the remains of a ceramic workshop where imperial-style vessels were produced (AD 1400–1530s). Cheqoq was a multiethnic settlement of forcibly migrated retainer laborers working for the noble lineage of the Inka ruler, Wayna Qhapaq. Production of imperial-style pottery in a small workshop associated with a royal lineage indicates that the heartland craft economy was not centralized in the urban Cuzco capital. The material remains of in situ production—raw materials, manufacturing facilities, tools, and by-products—provide a baseline for comparing other Inka pottery assemblages to this production locus.

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.

Ten or more features, each consisting originally of an open circle formed by a series of small holes, are present on two Late Archaic superimposed prepared floors at a shellmound on the outer coast of Chiapas, Mexico. These puzzling features bear a strong resemblance to ethnographic and ethnohistoric scoreboards used in indigenous dice games. Accordingly, the approximately 5,000 year-old features also were most likely game boards. Archaeologists have traced other Mesoamerican games into deep prehistory, including rubber ball games and another dice game known in Aztec times as patolli. These data provide evidence for the cultural importance and longevity of gaming in Mesoamerica.

Excavations at Abreu Garcia provide a detailed case study of a mound and enclosure mortuary complex used by the southern proto-Jê in the southern Brazilian highlands. The recovery of 16 secondary cremation deposits within a single mound allows an in-depth discussion of spatial aspects of mortuary practices. A spatial division in the placement of the interments adds another level of duality to the mortuary landscape, which comprises: (1) paired mound and enclosures, (2) twin mounds within a mound and enclosure, and (3) the dual division in the mound interior. The multiple levels of nested asymmetric dualism evoke similarities to the moiety system that characterizes modern southern Jê groups, highlighting both the opposition and the complementarity of the social system. The findings offer deeper insight into fundamental aspects of southern proto-Jê social organization, including the dual nature of the community, the manifestation of social structure in the landscape, and its incorporation into mortuary ritual. The results have implications for research design and developing appropriate methodologies to answer culture-specific questions. Furthermore, the parallels among archaeology, ethnohistory, and ethnography enable an understanding of the foundation of modern descendent groups and an assessment of the continuity in indigenous culture beyond European contact.

The present paper aims to reconstruct lifestyle and health parameters of three populations from Puémape site on the Peruvian north coast, Central Andes, active during the Formative Period (2500-1 B.C.). Since the factors that led to social complexity and its relation to crop-based subsistence are still being discussed, this analysis of 85 well-preserved individuals using 12 osteological markers for nutritional and functional stress, infectious diseases, and interpersonal violence offers the opportunity to understand the biological dimension of this process. Although we observe auditory exostosis in all samples, indicating the continuing importance of marine resources, other paleopathological findings, in accordance with archaeological data, support the idea of profound changes in lifestyle related to the rise of social complexity in the region. These include a 10 cm height decrease, changes in nutritional stress markers, and an increase in degenerative joint diseases in vertebra but not in the appendicular skeleton, whereas infectious diseases and violent trauma became more frequent. Thus, in Puémape we witness considerable changes in the way of life across the Formative period, associated with changes in diet, division of labor, and social stratification.

Recent investigations at Cahal Pech, Belize, documented a previously unrecognized Middle Preclassic (700–500 cal BC) E-Group complex. Located in an open public plaza, the monumental complex likely functioned as a forum for communal public events. In the Late Preclassic, the E-Group was replaced by an ancestor shrine where several royal tombs are located, as well as buildings separating public civic space from private elite space. These shifts in monumental construction temporally track the development of ideological manifestations of power and provide evidence for the formalization of dynastic rulership by an emerging elite class.

The investigation of social inequality in the Caribbean mainly has focused on the larger islands of the Greater Antilles where ethnohistoric records and monumental architecture form the basis for analysis of precolumbian complex societies. This paper presents evidence for status differentiation in the Lesser Antilles on the small island of Anguilla within a deposit at the Sandy Hill site and evaluates associated archaeofauna for evidence of rank-based differences in food consumption. When compared with three other sites, the higher density of status-related artifacts and higher densities of food remains at the Sandy Hill site are interpreted as the result of feasting. No evidence for inequality is observed in patterns of food consumption.

This article investigates the mechanisms by which different communities were articulated during the Late Intermediate period (ca. AD 1000–1450) in the Río Grande de San Juan Basin, also called the Chicha Region, located in the border region of Bolivia and Argentina. Through analyses of systems of pottery production, circulation, and consumption, we examine interaction networks, social integration, and alliance building at a regional level. Yavi-Chicha pottery from two sites in the Chicha Region—Chipihuayco, in the Talina Valley (Bolivia), and Finispatria, in San Juan Mayo (Argentina)—provide key insights into regional integration and constellations of practice through their localized technological style and shared consumption strategies. This study reveals that people of Finispatria incorporated the entire Yavi-Chicha-style household assemblage—partly produced in Chipihuayco, partly in Finispatria, or partly at some unknown location—into their everyday lives. We argue that the entire household ceramic repertoire of the study region played a fundamental and socially integrative role as it circulated across the region.

In this report we introduce the site of Noh K'uh, a Late Preclassic (400 BC–AD 250) community in the western frontier of the Maya Lowlands. This new body of data contributes to the study of how complex societies emerged both within the Usumacinta River region and the Maya area overall.

The problem of finding the locations of ceramic production has limited interpretations of prehispanic Mesoamerican economies. A new method for locating pottery-making is offered that emphasizes ties between the process of clay extraction and the manufacture of ceramic goods at the same clay source. Observations at modern brick and roof tile-making factories (tejeras) in the Naco Valley, Honduras, show that an effective arrangement for intensive production of ceramic goods is to create the finished product at the clay source. The major topographic transformations caused by clay extraction at tejeras, such as borrow pits and escarpments, are also signatures of prehistoric clay removal and, in many cases, can contribute to the identification of ancient pottery-making locations. A potential production locus was identified at the previously unremarkable and peripheral Site 108, where excavations successfully uncovered a prehistoric pottery workshop. By expanding the scope of our research methodologies, in this case actually implementing ethnoarchaeological understandings to the archaeological record, and by gathering more evidence for ancient pottery production, in this case at clay sources in rural areas, we are better positioned to understand the complexities of Mesoamerican economies.

We present data produced through archaeological and geological survey, as well as geochemical analysis of the Zaragoza-Oyameles obsidian source area located on the northern and western flanks of the Los Humeros Caldera in eastern Puebla, Mexico. One result of the intensive archaeological surface survey of this obsidian source area was the identification of 117 obsidian flow-band exposures. Geologic samples from 40 of these were submitted for instrumental neutron activation analysis. Eighty-five projectile points collected from the surface were characterized using portable X-ray fluorescence. These analyses identified three sub-sources: Z-O1, Potreros Caldera, and Gomez Sur. The Gomez Sur sub-source appears chemically similar to the previously identified Altotonga source, located 25 km to the northeast. Results of the geological survey help elucidate the relationship of Altotonga obsidian with the Zaragoza-Oyameles source area. The data from the three sub-sources are compared to all consumer site data attributed to the Zaragoza-Oyameles source in the Missouri University Research Reactor database. Results indicate that the majority of consumer samples throughout Mesoamerica match the Z-O1 sub-source, while 4 percent match the Potreros Caldera sub-source. This information, combined with the Gomez Sur data, is discussed in terms of economic relations with the regional center of Cantona. Obsidian procurement and distribution may have been more nuanced than previously modeled. We suggest that a number of potentially independent communities in addition to Cantona may have been involved in distributing this obsidian throughout Mesoamerica.

Excavations west of the monumental core at Chavín de Huántar, Peru in 2005 revealed a well-preserved plastered structure with a central circular hearth, in the style of the Mito Architectural Tradition. This find challenges standard definitions of both the Mito Tradition and Chavín itself. I discuss the material remains and associated radiocarbon dates from this feature, and use these new data to re-assess Chavín’s involvement in interregional networks and its relationship to earlier ceremonial centers in the Central Andean highlands.

We take an archaeodemographic approach and provide new insights into the population and demographic shifts of the prehispanic site of Xcambo, Yucatan, Mexico. Located in the coastal marshlands, Xcambo functioned as a salt production locale, administration center, and port during the Early Classic (AD 250–550) and Late Classic (AD 550–750) periods. Sierra-Sosa extensively excavated the settlement, and more than 600 skeletons, representative of all age groups, were recovered. We apply growth simulation models that combine archaeo- and paleodemographic approaches. Our simulation specifically takes into account Wood's (1998) theorem. Results show that Xcambo grew slowly during the Early Classic, with estimated figures ranging from about 860 individuals at the onset of the period to some 1,073 at the end. During the Late Classic, populations ranged from about 1,103 to 1,728 people at its peak occupation (AD 625). Eventually population drastically declined due to out-migration. During this last stage, the settlement had to face the consequences of political and economic shifts in the area. Considered jointly, both approaches provide a new research venue, because their application documents the population profiles and growth of a typical Maya coastal site over its 500 years of occupation.

The important Classic period site of Teotihuacan is renowned for its great size, ancient influence, and intricately decorated polychrome murals. The latter are the focus of the present study, in particular the unique landscape scene from Murals 2 and 3 from Portico 1 of the North Patio of the Atetelco residential compound that depicts a row of toponymic hill signs. The three hills have identical qualifying elements embedded, identified as combinations of an owl and a spearthrower. The murals thus make a repeated reference to a place named “Spearthrower Owl Hill.” The dating of the murals to the Early Xolalpan phase (ca. A.D. 350–450) makes them contemporary with the so-called Teotihuacan entrada into the Maya lowland sites such as Tikal, where hieroglyphic texts make mention of a Teotihuacan-affiliated individual known as “Spearthrower Owl.” From these findings—and based on Mesoamerican naming practices—we go on to suggest that the Atetelco toponym and the historical individual share the name of a common forebear, possibly that of a previously unidentified Teotihuacan martial patron deity. As such, the Early Classic Teotihuacan “Spearthrower Owl” deity has much in common with the legendary Huitzilopochtli of the Late Postclassic Mexica. Our reexamination of the murals from Atetelco shows the enormous potential that further studies in Teotihuacan writing and iconography still have for our understanding of the history and religion of this major Mesoamerican site.
