This study uses stable carbon δ13C and oxygen δ18O isotope compositions data to assess the extent to which diet breadths of northwestern Guyana changed during the Holocene. We analyzed human bone and enamel remains from seven shell mound sites dating between 7500 and 2600 BP. Our analyses demonstrate some constancy in C3 plant availability during the past several thousand years, though we note increasing reliance on such plants beginning in the Early Holocene. We also document warming intervals during the Early Holocene (Early Archaic) that appear to correlate with dry periods known elsewhere in the central Amazon during this period.

Assessment of the nature of intrasocietal relationships in the context of the origin of state-level power is a critical area of study within anthropological archaeology. A well-established model of such emergent political relations (Wittfogel 1957) posits that differential access to land, coupled with intensification of agriculture, places common farmers in a position of inferiority, and thus subjects them to exploitation by the elite controllers of intensive agriculture. The central thesis of this article is that the initial relationship between the elite controllers and the common laborers in an intensive agricultural system was mutually beneficial, with the state only capable of exercising more exploitative power some generations after the establishment of intensive agriculture. I argue that the economic measure of marginal productivity may best reflect each farmer’s personal contribution to agriculture, and that, in a largely kin-based system, it is difficult for the emergent elite to exercise exploitative power when the marginal productivity of labor is high. I support the thesis on the basis of the simulated trajectory of marginal productivity, which indicates that marginal product increases with intensification. I explore the model further in a consideration of the rise of the Classic Maya kingdom of Copán, Honduras.

La región pacífica de Colombia presenta numerosas áreas inexploradas a lo largo de su litoral costero y tierras bajas. La región sur es la más conocida gracias a la importancia arqueológica de las zonas de Tumaco y La Tolita (Ecuador). Al norte de Tumaco recientemente se exploró la región del bajo Río Patía (Nariño). A traves de este trabajo se observaron asentamientos precolombinos relacionados con dos fases culturales: (a) fase Buena Vista y (b) fase Maina. Los pobladores precolombinos de estas fases se adaptaron básicamente a las áreas bajas de la llanura aluvial selvática y la región costera del sur de Colombia. Hacia finales del período de Desarrollo Regional costero, la fase Buena Vista (ca. 70–500 D.C.) culturalmente se encuentra relacionada con las fases tardías de El Morro y El Balsal de la secuencia establecida para la región de Tumaco (Nariño). Estas fases a su vez forman parte del período tardío “decadente” de la tradición Tumaco-La Tolita (ca. 400 A.C.-500 D.C.) de la costa sur de Colombia y norte del Ecuador. Igualmente, la fase Buena Vista se relaciona con la fase Guadual (ca. 200–600 D.C.) de la cuenca de los ríos Santiago y Cayapas, en el norte de la costa ecuatoriana. Posteriormente, la llegada de nuevos grupos al bajo Patía se representa por asentamientos de la fase Maina datados hacia el 880 D.C., hasta, probablemente, el contacto europeo. Esta fase se caracteriza primordialmente por una industria alfarera sencilla y poco decorada en relación con la cerámica de la fase anterior. Algunos de los sitios tardíos a su vez podrían corresponder a asentamientos de grupos Sindagua que ocuparon el área al tiempo de la Conquista y la Colonia, en los siglos XVI y XVII.

Recently, an exceptional find was made by the Nakum Archaeological Project in an offering deposited deep within the architectural core of the Precolumbian Maya site of Nakum located in northeastern Guatemala. The form of the object and comparisons made to ethnographic analogs indicate that it is a clay beehive, most probably one of the oldest in the Maya area and in the whole of Mesoamerica. Whether the object was used for its intended function or is an emulation, or skeuomorph, of perishable counterparts, remains unknown. The importance of this find lies in the fact that beekeeping is an activity that is traced with difficulty in archaeology. The present paper discusses the discovery of this artifact at Nakum, which dates to the end of the Preclassic period (ca. 100 BC–AD 250/300), in a wider temporal and spatial context and provides new data on Precolumbian beekeeping. We use a broad comparative vantage, drawing on archaeological, epigraphic, and ethnohistorical sources to discuss Mesoamerican beekeeping and its role in both the daily and the ritual lives of the Maya.

This article discusses the measurement system used at Cacaxtla, Tlaxcala, Mexico. It addresses the ideological concepts this system may have expressed, its relationship to other systems used in Mesoamerica, and its implications for evaluating the hypothesis of a Maya presence at Cacaxtla during the Epiclassic. Measurements used at Cacaxtla combine the practical needs of builders with symbolic expression reflected in architecture. Two moduli served as the basis for the dimensioning: the unit of .488 m and its triple, 1.465 m. This measurement was in turn multiplied by 3,4,9, and 12 to obtain the lengths of the main spaces, which served as the basis for the dimensioning system used during different phases of construction. In specific places, three anthropometric measures were used. Additionally, the spatial distribution of pillars according to their sizes confirms the coexistence of two zones within the site that express a duality also present in mural paintings. The moduli and units used at Cacaxtla agree to a considerable degree with those identified for the Maya area and, in some cases, with Teotihuacan and the Nahua culture. I hypothesize that this system was shared by several Mesoamerican cultures and lasted from the Classic to the Postclassic periods.

Since its introduction, the study of artifact design has shed new light on the nature of variability in prehistoric technological organization. Few ethnoarchaeological studies exist exploring the interrelationships between subsistence risk, the costs of technological failures, and the design of artifacts. This ethnoarchaeological study investigates these relationships in a transhumant agro-pastoral case study from the southwestern Bolivian altiplano. Three aspects of tool design are explored to document variability in design characteristics between and within assemblages from agricultural and pastoral residences. These design features consist of the reliability of raw materials used in tool manufacture, the reliability of joints used in compound tools, and the maintainability of tools in case of partial or total failure. While time-budgeting constraints differ at pastoral and agricultural residences, the costs of production shortfalls are equally severe. In response, artifacts from both residences are designed to be highly reliable. However, depending on the likelihood of tool failure, artifacts are designed with different raw material and joint reliability to either minimize tool failure or maximize maintainability. Multiple backups and replacement components are accumulated and maintained to reduce subsistence risk caused by the failure of artifacts with high potential failure rates or low maintainability.

El estudio de la iconografía escatológica producida por los mochicas de la costa norte del Perú prehispánico (ca. 50 A.C.-750 D.C.) coloca en evidencia la presencia de diversos personajes lisiados, y más precisamente figurantes masculinos con un pie o los dos pies faltantes. ¿Cuál fue el significado ideológico y político de este elemento simbólico y su importancia en la dinámica del poder mochica? En las escenas que ilustran el mundo de los vivos, estos lisiados forman parte de un grupo, que he llamado “los Intendentes,” puesto al servicio del dirigente mochica. En las escenas del mundo de los muertos, un lisiado de apariencia esquelética (“el Esqueleto con prótesis”) parece igualmente servir al dirigente fallecido. Poniendo en relación estas representaciones con descubrimientos arqueológicos pertinentes, un análisis contextual permite liberar una figura simbólica mayor de la imaginativa de los mochicas, metonimia del orden social y político, que he llamado el “Personaje del pie amputado.” Pareciera que esta figura pudo simbolizar, a la vez en la iconografía y a la ocasión de ciertas prácticas rituales y de sacrificio, la perennidad de la estructura de poder, especialmente a partir de la fase III y posteriormente. Este tipo de análisis contextual permite estudiar desde un nuevo ángulo los elementos constitutivos de la estructura de poder mochica y da nuevas perspectivas para la comprehensión de la dinámica del poder en las sociedades complejas.

El estudio de la génesis de los montículos de la cuenca de la Laguna Merín, Uruguay, se focalizó en el aporte de sedimentos y elementos descartados. Investigaciones basadas en la geoquímica de la matriz llevaron a considerar el rol del fuego en su elevación. Ensayamos contrastar su presencia por medio de las técnicas de datación por luminiscencia. Si las edades o paleodosis medidas por luminiscencia ópticamente estimulada (OSL, por sus siglas en inglés) y por termoluminiscencia (TL) de diferentes fracciones de la matriz son similares, próximas o con cierto grado de superposición, entonces el agente de blanqueo tiene que haber sido el calor. La hipótesis fue verificada en montículos de tres sitios arqueológicos ubicados en el sur de la cuenca. La evidencia de que estaríamos frente a prácticas recursivas que producen acumulaciones de sedimento termoalterados nos condujo a los hornos de tierra y los oven mounds de Australia. La presencia de hornos de tierra prehistóricos ya fue reconocida en Uruguay. Los oven mounds son un potente análogo etnográfico-arqueológico que ilustra sobre procesos de formación de acumulaciones de sedimento termoalterado, al mismo tiempo que permite abordar aspectos socioeconómicos y simbólicos. Por último, a partir de las implicaciones de la hipótesis, señalamos la pertinencia de abordar los montículos a dos escalas: la de los comportamientos que los elevaron y la de su realidad como parches dentro del paisaje.

During the Epiclassic period (AD 600–900), the northern frontier of Mesoamerica consisted of a regional network of polities focused on large, hilltop centers, including the site of La Quemada in the Malpaso Valley of Zacatecas, Mexico. Although extensive archaeological research has been conducted at the site, the refinement of its chronology is essential for two reasons: (1) to establish the chronological control necessary to characterize social processes diachronically and (2) to ensure that the occupational history of La Quemada is accurately integrated into the regional chronology of the northern frontier. A combination of frequency seriation, correspondence analysis, and discriminant function analysis results in the recognition of three occupational phases across the areas excavated by the La Quemada-Malpaso Valley Archaeological Project (LQ-MVAP). Our three-phase chronology independently confirms both the intra-context ordering of analytic units and the previously proposed growth trajectory of the site: beginning in the monumental core, expanding into the western flank, and later retracting back into the core. The separation of the LQ-MVAP material record into chronological phases means it is now possible to track changes in the social processes that may have contributed to the formation, maintenance, and decline of La Quemada and other northern frontier polities.

The sixteenth-century indigenous societies who inhabited the Pacific plains of Panama have occupied an important place in discussions of social hierarchy in the Americas. Beginning with the discovery of the richly stocked tombs at Sitio Conte in the 1930s the origins of social hierarchy and wealth accumulation has been a key theme in the Central Region of Panama. Although the most lavish burial hoards at Sitio Conte contained hundreds of sumptuary goods elaborately decorated with cosmological iconography, no other contemporary cemetery shows evidence for this degree of wealth accumulation. The only other site with mortuary patterning suggestive of high ranking individuals is He-4, where high ranking mound burials were interred following the abandonment of the Sitio Conte cemetery. From a macroregional perspective the increase in access to prestige goods in mound burials at He-4 contemporaneous with, or immediately after, the decline of Sitio Conte is best explained as a result of changes in political organization of the kind often associated with the growth and decline of chiefly polities.

Huencú Nazar es un sitio arqueológico a cielo abierto localizado en el Sistema Lagunar Hinojo-Las Tunas (región pampeana, Argentina) que fue ocupado durante el Holoceno tardío (ca. 3000 aP). En un área de 5.000 m2 se distribuyen 22 fogones, escondrijos de roca y concentraciones de rocas granitoides. En uno de los sectores excavados se registraron fogones en cubeta y el uso de huesos de Lama guanicoe (Artiodactyla, Camelidae) como combustible. El uso de combustible óseo permitió solucionar el problema de los residuos molestos para la comodidad de las personas ubicadas alrededor de los fogones. En torno a las estructuras de combustión se depositaron materiales relacionados con la subsistencia y la tecnología.

A través de la morfometría geométrica, este estudio explora la influencia del contexto cronológico y de procedencia en la variabilidad morfológica de 75 anzuelos de concha de Choromytilus chorus provenientes de siete sitios arqueológicos de la comuna de Taltal, en la costa sur del Desierto de Atacama, Chile. Los resultados muestran diferencias significativas en las formas de los anzuelos provenientes de distintos sitios y períodos. El rasgo que explica el mayor porcentaje de variación morfológica es el largo de una de las puntas, seguido por la abertura del anzuelo. Se identifican tres momentos clave en la evolución morfológica de estos artefactos. Entre 8500 y 7500 cal aP aparecen los primeros anzuelos, predominantemente sin vástago y de abertura amplia pero variable. De 7500 cal aP en adelante, la tecnología prolifera y se diversifica: los anzuelos sin vástago y con abertura amplia siguen predominando, pero formas con vástago y abertura media también están presentes en el kit de pesca. Finalmente, entre 5500 y 4500 cal aP el número de anzuelos disminuye, desaparecen las formas circulares y se mantienen las formas con vástago, pero con abertura más estrecha. El caso de estudio de Taltal contribuye a enriquecer el conocimiento sobre la tecnología del anzuelo en concha a lo largo del Pacífico.

Recent excavations at the Initial Period (1800-900 B. C.) site of Pampa de las Llamas-Moxeke in the Casma Valley, Peru, have revealed the presence of an I-shaped court that is architecturally very similar to prehistoric I-shaped ball courts commonly found in Mesoamerica. Although it is possible that there is a connection between the I-shaped court at Pampa de las Llamas-Moxeke and those of Mesoamerica, such a connection appears unlikely given the isolated nature of the former court in terms of time (700 years too early) and space (2,500 km too far south). It seems much more probable that this unique I-shaped court housed a special religious or secular activity within Pampa de las Llamas-Moxeke and represents a possible unrecognized facet of early complex society during the Initial Period.

In this article, I investigate the Northern and Southern Moche archaeological cultures by evaluating the data gathered and theories developed since their first identification 25 years ago. I suggest that what was previously considered the Southern Moche tradition was the dominant one throughout most of the North Coast, with regional variations, prior to about AD 650. After that date, the “Classic Moche” tradition ended in both regions and was succeeded by distinct Northern and Southern ceramic and mortuary traditions and, inferentially, reorganized social, political, and religious systems as well. The relations between regional mortuary and other traditions and fineware styles are considered in light of pan-regional dynamics including the ascendancy of the Wari Empire.

Uno de los temas centrales de discusión en la arqueología de Patagonia se enmarca tradicionalmente en torno a la profundidad temporal de las ocupaciones humanas y su relación con el estudio de las estrategias de movilidad de los grupos cazadores-recolectores que habitaron diferentes espacios. A partir de la calibración y la suma de probabilidades de una muestra actualizada de dataciones radiocarbónicas obtenidas para la cuenca inferior del río Deseado, se identifica una secuencia ocupacional discontinua que se desarrolla durante el Holoceno medio y tardío. La información paleoclimática a escala regional y el carácter exploratorio de las ocupaciones humanas sugieren que un hiato cronológico identificado hacia el final del Holoceno medio (4988-3978 cal aP) podría estar vinculado con estrategias de abandono y relocalización del área, en función de dar respuesta a condiciones de aridez que habrían configurado un ambiente con escasa disponibilidad hídrica. Durante el Holoceno tardío final (entre ca. 1500 y 300 cal aP), el registro de espacios costeros ampliamente habitados y la identificación de un marcado crecimiento de la densidad de probabilidad de la curva de distribución de dataciones sugieren una trayectoria hacia un aumento poblacional en el marco de estrategias de movilidad asociadas al litoral atlántico.

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.

Archaeological studies of culture contact often presuppose culture change. Contact that did not result in culture change is difficult to identify archaeologically, but it merits our attention for understanding how and why change failed to materialize in the wake of cultural encounter. In this paper, I examine the occurrence of contact without change on the frontier of the south-central Andean Tiwanaku state (AD 400–1100). Tiwanaku settlers who colonized the uninhabited middle Moquegua valley in the seventh century AD shared a mortuary landscape with coastal sojourners at the site of Omo M10, even though their interactions were otherwise limited. Complex regional histories and divergent economic interests explain why contact between highland and coastal groups was confined to mortuary rituals during the initial stage of contact, following a Tiwanaku pattern in Moquegua of ritualizing culture contact. Later generations of Tiwanaku colonists may have reinitiated contact with coastal communities for access to marine resources, and accepting foreigners into their community. This case study presents a framework for identifying culture contact without culture change. It demonstrates the utility of regional histories and careful contextual analysis for hypothesizing the nature and consequences of cultural encounters that did not follow expected trajectories of change.

In this article, we present research on Inka actions in the face of resistance by indigenous peoples on the northern frontier. We link fieldwork at the Pambamarca complex in northern Ecuador with historic documents to provide important context for further examining imperial processes. With its three site types, Pambamarca offers an opportunity to examine the range of tendencies that groups undergo during imperial moments. Its sites show evidence of both direct displays and the materialization of forceful control or takeover, as well as the more passive, nonsettler, decentralized hegemonic narratives also commonly associated with empire. Here we present detailed data for Inka military installations used to confront a prolonged resistance by the País Caranqui, a decentralized confederation of Caranqui-Cayambe peoples. Evidence from surveys and excavations— including architectural planning, distribution of artifacts, and military encounters—at two large sites in the complex, Quitoloma and Campana Pucara, helps expand our current understandings of the Inka invasion in northern Ecuador while broadening our perspective on the imperial narrative in South America.
