Agriculture in prehispanic Mesoamerica necessitated not only a wide range of knowledge regarding soil types, fertility, and the growing cycles of different plants, but also the attendant rituals that firmly situated agrarian production into a shared Mesoamerican worldview. Due primarily to archaeological visibility, those attendant rituals have traditionally been investigated within the context of large centers. Recent investigations at the site of Quincunx, a hinterland architectural complex in northwestern Belize of the Maya Lowlands, provide evidence that some rural communities may also have had access to and control over esoteric knowledge involved in agricultural practice in the Late Classic period. Our findings are discussed in the context of ethnographic accounts and archaeological data that reveal the deep significance of quincuncial designs in Maya society and Mesoamerican ritual practices.

Recent archaeological study of the architecture at the Wari site of Pikillacta provides information concerning the function of one of three basic Wari architectural forms. These buildings, called Type II niched halls, occur at both Pikillacta and Viracochapampa, the two largest known Wari provincial sites. Their function can be deduced from a variety of evidence: data from excavations and associated artifacts, analogy with earlier, contemporary, and later Andean ritual/ceremonial buildings, and representations of buildings in Wari art. Based on this analysis, the niched halls apparently served as lineage halls where both real and fictive kin came to formally worship their ancestors. It is suggested that co-option of conquered elites by adoption, and thereby establishing a set of reciprocal obligations, may have been a strategy practiced by the Wari as a principal feature of their statecraft.

This paper analyzes the biographical and related archaeological information of 10 artificially shaped skulls from the broader Maya area, which bear resemblance to the high and narrow head morphology depicted in Olmec art. The skeletal evidence of this head form, which was accomplished by combining compression cradleboards with constricting horizontal wraps (tabular erect type in its pseudo-circular variety), is rare and predates A.D. 250 in all cases. Here I compare the cranial vaults shaped in this fashion with that of 49 other Preclassic period Maya indivisuals from different parts of the Maya world. The discussion explores the possible evolving social and religious roles of this emblematic body modification. I argue that Olmecoid head modification was a syncretic cultural adoption, since it was just one of many expressions of a deeply embedded Preclassic tradition, still practiced centuries after the demise of Olman’s societies themselves. The visible effect of the artificial pear-shaped heads most likely reflected gradual shifting ideological schemes, probably emulating early versions of the Maya Maize God, given the resemblance to Preclassic period renderings of this supernatural force.

This study examines archaeofaunal materials contained within a large bell-shaped prehistoric pit from the site of Pechichal (M3B4-011) in northern Manabí Province of lowland western Ecuador. This feature provides a high resolution archaeological context for understanding assemblage accumulation and deposition, and provides important data for inferring local environmental conditions. The archaeofaunal assemblage can be divided into two distinct groups based upon the vertical representation of its skeletal remains throughout the pit. One group, characterized by variable skeletal representation and vertical concentration, likely includes both culturally disposed and naturally entrapped taxa. The other group, characterized by a few isolated fragments, low skeletal completeness, and dispersion in vertical profile, is likely dominated by culturally disposed taxa. When the natural histories of the pit faunas are considered along with their distinct numerical representation, the entire pit assemblage makes ecological sense. The data suggest that the pit was located at the edge of a modified forest fragment.

The absence of suitable methodologies to distinguish between wild and domesticated camelids in rock art has limited the interpretation of visual preferences of Andean prehispanic cultures. Although rock art’s contextual information may provide some indications that help to differentiate between wild and domesticated animals, uncertainty prevails because the relation to camelid forms is indirect. Zoological and zooarchaeological knowledge of South American camelid morphology is used as a means of comparison and identification in Atacama Desert rock art attributed to the Initial Pastoral phase (1500–500 B.C., Early Formative period, northern Chile). Based on this analysis, there are strong arguments for a distinctive graphic representation of wild as opposed to domesticated camelids, as well as a correspondence of these representations to two different modes of subsistence—one of hunters and the other of husbandry-pastoralist societies—which would have coexisted during this transitional period.

The significance of a microlithic assemblage composed of imported, nonlocal materials is discussed for the Three Dog site, an early Lucayan site located on San Salvador, Bahamas. The Bahama archipelago is an interesting area in which to examine the organization of technology because the islands lack cherts and other suitable materials for chipped stone manufacture, suggesting that economizing strategies may have been practiced. The artifacts were manufactured by bipolar production and a few show evidence of recycling and reuse. Microwear analysis, undertaken to determine function, was inconclusive due to heavy weathering from the depositional environment. Traces of an organic adhesive suggest that some of the objects were used as hafted or composite tools. The presence of starch grains, most likely Xanthosoma sp., and other plant residues on some artifacts suggests they were used in plant processing. The morphological similarities of the flakes produced through bipolar reduction with those from ethnographic sources suggest that most of them probably were used as grater chips to process root or tuber foods. The assemblage was compared to other bipolarly-produced microlithic assemblages from nearby islands.

Investigations at the Ramaditas site (Guatacondo Valley, northern Chile) were successful in the discovery of small quantities of ancient metallurgical slag, copper ore, and metal from sealed archaeological contexts dating to the first centuries B. C., and in the discovery of adjacent off-site furnace ruins that appear to be contemporaneous. Laboratory tests are positive in identifying both the surface and subsurface slag as a copper smelting by-product. These results are significant in that they demonstrate that copper smelting and metal manufacture were taking place in the Atacama in antiquity, constituting the first conclusive proof of what many Chilean scholars have anticipated since the early 1970s. These results support the view that the mining of minerals and the winning of metals played a valuable role in the economy of the first sedentary villages of interior Chile, in the foothills and valleys that rim the Atacama desert.

During the Middle Horizon (A.D. 600-1000), the Wari state extended its influence over much of Peru. One popular view of the Wari expansion is that the state constructed a system of administrative centers that ruled through an idiom of generalized reciprocity and extracted, stored, and redistributed goods from local groups. This paper considers how this model of the Wari periphery was constructed over the last 100 years, and argues that interpretations that fit within this model have been given added weight in academic literature because they fit our expectations of what the past should be like. I suggest that there are significant problems in this understanding of the Wari periphery that need to be addressed, and offer an alternative model that better fits the available evidence.

Cahal Tok (Place of Flint) is a limestone rise with some structural evidence, associated with the previously designated LDF Chert Site, close to the ceremonial center of El Pilar. Excavations uncovered evidence that during the Late Classic period, specialized flintknappers produced bifaces, primarily chert axes, at the Cahol Tok locus, first on a cleared limestone shelf then on a prepared cobble platform. Small flakes remained in situ whereas much of the larger debris was deposited to the east off the edge of the platform and into the LDF debitage dump. The identification of a specialized manufacturing locale near the ceremonial precinct of a major center is unusual in Maya archaeology. Central control of an important industry may be implied, although knapping could equally well be organized more independently. We expect that small industrial areas are actually present at most large sites, but may often be difficult to recognize.

En este trabajo se describen las relaciones que las sociedades humanas establecieron con su entorno durante el período Formativo (3000-1000 aP) en la Pampa del Tamarugal, Desierto de Atacama, desde una perspectiva teórico-metodológica que pone el acento en el potencial del registro ecofactual. Éste, al mediar entre lo cultural y lo ambiental, proporciona información vital para una mejor comprensión de la relación entre naturaleza y cultura construida por estas sociedades. Queremos demostrar que este proceso forma parte de una larga historia de racionalización del desierto y de sus recursos silvestres, locales e introducidos, así como de la vivencia particular que tuvieron estas comunidades andinas. Por consiguiente, proponemos que la intervención humana en la Pampa del Tamarugal puede ser entendida como un cambio no sólo ecológico y económico, sino también cosmológico.

Salt has always been a strategic resource of primary importance. In Prehispanic times, salt was used mainly for human consumption, and after the Spanish conquest it became, in addition, an important commodity for silver processing and cattle raising. Salt production and trade in the Lake Cuitzeo basin are analyzed from the perspective of ethnography, archaeology, and ethnohistory. We know that salt from Araró, one of the towns where this research is focused, was paid as tribute in the early colonial era. Ethnohistorical sources concerning salt production in the Lake Cuitzeo basin are discussed, including information on the quantity of salt paid by each town in the first half of the sixteenth century. Contemporary salt-producing sites and methods are described, including the amount of brine and earth used, and the average yield of each finca, or salt-producing unit. Modern and ancient techniques and processes are compared, and found to be similar. The “archaeological visibility” of these activities is assessed, using examples from several areas of Mesoamerica to illustrate the archaeological features and artifacts (e. g., mounds, canals, and specialized pottery types) connected with salt making.

One of the most enigmatic aspects of decapitation practices among south coastal Peruvian Paracas and Nasca cultures (900 B.C.-A.D. 750) is the near absence of headless bodies in the archaeological record. Drawing on a case study of an Early Nasca, Phase 3 headless burial at Site PV62D13 in the lower Ica Valley, together with examples of headless interments reported in the literature, I examine the nature and disposition of headless burials. Three burial patterns, or forms, are proposed. The burial at PV62D13 is distinguished for its extended posture and interment in a non-cemetery setting and is proposed to be a dedicatory burial. Burial forms for disembodied heads are also examined, and over time, a notable increase in cached heads, buried without grave offerings is observed. Painted ceramic images of Nasca trophy heads and headless bodies are reviewed diachronically and a marked increase in decapitation scenes is noted for Late Nasca. Attention is drawn to the limited number of headless body images overall, and possible solutions to reconcile the visual imagery with the archaeological data are offered.

The coastal plains of the States of Paraná and Santa Catarina, in Southern Brazil, were first settled around 6000 B.P. by shellmound builders, a successful fisher-hunter-gatherer population that inhabited the coastal lowlands practically unchanged for almost five thousand years. Shellmounds were typically occupied as residential sites as well as cemeteries, andare usually associated with rich alimentary zones. Around 1200 B.P., the first evidence of ceramics brought from the interior is found in coastal areas, and together with ceramics there is a progressive abandonment of shellmound construction in favor of flat and shallow sites. Here we consider if these changes were reflected in the postmarital residence practice of coastal groups, i.e., if the arrival or intensification of contact with groups from the interior resulted in changes in this aspect of social structure among the coastal groups. To test the postmarital residence practice we analyzed within-group variability ratios between males and females, following previous studies on the topic, and between-group correlations between Mahalanobis distances and geographic distances. The results suggest that in the pre-ceramic series a matrilocal, postmarital residential system predominated, while in the ceramic period there was a shift toward patrilocality. This favors the hypothesis that the changes experienced by coastal groups after 1200 B.P. affected not only their economy and material culture, but important aspects of their sociopolitical organization as well.

Archaeological, ethnohistoric, and ethnographic evidence provides ample indication that water was a key symbol in Andean thought. During the late precolumbian era, the attention lavished on waterworks and features by the Inca emphasizes a clear concern with control over water and its movement. This paper examines the way in which specific relations of power and identity were constructed through Inca management of water. To this end, I offer a comparative analysis of water-related features from different sectors of the Empire, representing different moments in its historical development. The intent is to further our understanding of how the manipulation of water figured in the imperializing process and how its use and meaning may have evolved over time. The architectural evidence from the sites included in the study suggests that conspicuous exercise of control over the movement and flow of water may have been more critical to the establishment of Inca hegemony than to its subsequent maintenance.

Compositional analyses have long been used to assign obsidian artifacts to particular source areas. In most cases, the chemical “fingerprint” of a particular source area has been determined through the assay of only a few geological specimens from one or two outcrops. As a result, the full range of intrasource compositional variation has rarely been noted, and its spatial patterning frequently has not been studied. This report describes the results of geoarchaeological survey at the important Guatemalan source area of San Martín Jilotepeque. Neutron activation analysis demonstrates the presence of seven distinct chemical “fingerprints” corresponding to spatially discrete subsources within the region. Ancient procurement and production are associated with only three of these subsources. Statistical procedures that can be used to assign artifacts to particular quarries or quarry systems are presented. Several minor Guatemalan source areas also are examined, and one (Media Cuesta) also can be characterized as consisting of two distinct subsources.

Over a decade ago Kenneth Hirth (1998, 2000) developed a “distributional approach” for archaeologically inferring the existence of marketplace exchange based on analyses of domestic artifact collections. Domestic collections, he reasoned, will be relatively homogeneous in areas where most or all households rely on marketplace exchange to acquire domestic provisions. The present study evaluates Hirth’s distributional approach using a statistical measure of diversity (heterogeneity) to quantify variability among domestic collection units over a large area. The data for this study come from the Middle Postclassic lower Blanco region of Veracruz (A.D. 1200–A.D. 1350), an unknown context of marketplace exchange. A comparison of diversity scores calculated on surface sherd collections from the lower Blanco region with scores from Late Postclassic Teotihuacan (A.D. 1350–A.D. 1520)—a known context of marketplace exchange—suggests the existence of a marketplace exchange system in the lower Blanco region, likely centered at the town of El Sauce. In addition, changes in intercollection diversity (sherds) and obsidian concentrations with increasing distance from the center suggest El Sauce’s market service area encompassed a radius of approximately six to nine kilometers.

Temples provide sanctuary, a home for the gods, a place to worship, a stage for ceremonies, a depository for offerings, and a place to redistribute goods. Finally, temples provide an arena for political competition. The role of Maya temples, however, is not so clear. Inscriptions, when present, detail who built some temples, but not if nonroyals built them, if they were built for specific gods, and why the Maya built so many. The presence of several temples in any given center might indicate that various groups built them and that they served as arenas to compete for status, prestige, and power. If this were the case, then people may have had a choice at which temple to worship and support. To explore the politics of temple construction, I compare temple size, location, construction patterns, and ritual deposits at temples at the secondary center of Yalbac, Central Belize. Preliminary results from temple looters' trenches have exciting implications regarding temple histories in the southern Maya Lowlands during the Late Classic period (ca. A.D. 550-850).

The domestication of llamas and alpacas was fundamental for the cultural and economic development of Andean societies, but the origins of camelid pastoralism as a distinct mode of socioeconomic organization remain little understood. Whereas most archaeological interpretations of prehispanic highland societies emphasize the transition from hunting-gathering to agriculture as a process marked by the establishment of agricultural sedentary villages, other subsistence and mobility strategies have been for the most part overlooked. A case in point is the Wankarani cultural complex from the Central Altiplano of Bolivia, which has been interpreted as an example of an early village-based sedentary society. Here, I argue that a model of mobile pastoralism based on ethnoarchaeological research better explains the Central Altiplano's Formative period archaeological record. Recently collected data support this proposition. Settlement patterns consisted of multiple dispersed camps attached to residential bases occupied recurrently. Horizontal excavations from a residential base revealed structures and features analogous to pastoralist landscapes documented around the world. Faunal identification confirmed the preponderance of domesticated camelids. Based on this evidence, I argue that we need better explanatory frameworks for approaching the origins, organization, and variability associated with early food producing societies such as mobile camelid pastoralists.

The burial found at Patapatane Cave in the highlands of Arica, northern Chile, yielded an incomplete skeleton of a 20-to-23-year-old female, dating to the end of the Middle Archaic period at 5910 ± 90 B.P. The site is located in a semiarid environment on the eastern side of Sierra de Huaylillas at 3800 m. in the hinterland of Arica, northern Chile. We argue that the missing bones, position of the cranium, and breakage of some elements resulted from both postdepositional human intervention and taphonomic processes. The body was laid to rest in a supine position and after it became skeletonized hunters revisited the inhumation and removed some bone elements. However, the other bones present in situ were not displaced and remained in proper anatomical position, with the exception of the cranium, which was placed vertically on top of the cervical vertebrae. The observed breakage of vertebrae, long bones, and skull seems to have been the result of taphonomic, nonanthropogenic, postburial actions. In reporting on the Patapatane burial, Archaic period funerary patterns from western South America are reviewed to support the notion that early hunters and gatherers systematically manipulated their dead through perimortem and postmortem alterations. These included several processes: (1) processes of body reduction and transformation by removal of body sections or removal of bone elements, cremation, and human remains discarded in domestic middens; and (2) processes of artificial preservation of the dead that included roasting, salting, and artificial mummification. In addition, we recognize the simultaneous existence of intact primary burial and that other skeletons were possibly altered accidentally by postdepositional natural or cultural agents.

Geometric earthworks located in the interfluvial zone of the Upper Purús and Madeira river tributaries in the southwestern Amazon are formed by ditches of varying shapes and sizes along with contiguous exterior embankments and roads terraced with low backfill banks. The earthworks in the Brazilian state of Acre were used from 1200 B.C. to the fourteenth century A.D., indicating a continuous, collective cultural institution, a generalized regional phenomenon characterized by local variants and alterations and probably not exclusively restricted to a specified ethnic group. The carefully planned position of the earthworks in the landscape and the recurring geometric forms represented in this earthwork architecture suggest functions that were part of a tradition of shared ideology related to rituals and/or the sociopolitical activities of ancient Amazonian peoples. Recent archaeological fieldwork on two composite earthwork sites, Fazenda Atlântica and Quinauá, situated in the core location of the geometric earthworks, provides further evidence for the predominantly ceremonial use of these constructions.
