  Early Agricultural period (circa 2100 B.C.-A.D. 50) archaeological sites embody the transition from foraging to the establishment of permanent, irrigation-based agricultural villages in the Sonoran Desert region of the southwest US/northwest Mexico. Developing concepts of corporate organization would have created a need for mediating social identities and interests between lineages and the community, and mortuary practices provide one mechanism likely employed to mitigate social tensions among households. Early Agricultural period normative mortuary practices are largely characterized by single, flexed primary inhumation with limited funerary objects and little apparent expression of social differentiation. The performance of mortuary rituals contributing to these material patterns likely functioned to incorporate a shared community identity, while placement within sites legitimized household interests through descent and inheritance. However, some variability is also observed throughout the period, including numerous body configurations, multiple burials, and cremation and could reflect the expression of personal social identities and/or different cosmological dogma.

  Detailed investigation of dental wear can provide information about diet, food preparation, pathology, idiosyncratic behaviors, and occupational activities. The application of standard scoring approaches, however, obfuscates the wide variety of aberrant wear observable within and across populations. Dental wear begins from multiple etiologies but cascades into complex inter-connected relationships that vary across the arch and between jaws. Wear resulting from one etiology may cause changes in occlusion that affect the manifestation of other forms, thus the analysis of aberrant wear cannot be undertaken without first parsing relationships among co-occurring etiologies. While such interactions complicate problem-oriented studies of dental wear, the complex intermingling of wear types reflects the value of teeth as a site for holistic interpretations of embodiment (e.g., of subsistence and other cultural activity). Here, we develop a model of aberrant dental wear that assesses both proximate (e.g., attrition, erosion, etc.) and ultimate etiologies (i.e., behavioral vs. occlusal) through the description of wear in terms of dentition, tooth class, tooth surface, and wear morphology. The goal of this model is to apply a systematic approach to the analysis of aberrant wear, to define the varied cultural phenomena embodied in the teeth with greater clarity. After outlining the model, we consider the implications of this approach for the interpretation of aberrant wear as an embodiment of social phenomena and explore the potential of such wear as a proxy for communities of practice.

  This volume pulls together experts representing a range of current approaches to the study of dental wear in extant primates, hominins, and ancient humans to highlight advancements in macrowear and microwear analyses, particularly those regarding diet, extramasticatory behaviors, and tooth use via evolutionary and biocultural perspectives. As biostructures that facilitate interaction between bodily and external environments, teeth provide the first step in the digestion of food through mechanical breakdown. But by engaging in their primary function, teeth experience wear from tooth-to-tooth and tooth-food-tooth contact as well as chemical erosion. Tooth wear reflects the interaction of tooth form and use and therefore provides insight into the evolutionary history of our primate relatives and hominin ancestors; it also documents dietary nuances in modern humans as they dispersed and inhabited a great variety of geographic regions. As a complex, multifactorial process, tooth wear has garnered significant attention at both macroscopic and microscopic levels. Improvements in the understanding of chewing mechanics and dental hard tissue properties, along with recent applications of technology capable of analyzing dental microsurfaces, has led to a fluorescence in dental wear study and generated a rich and extensive literature. This volume serves to underscore the value of studying dental wear in biological anthropology and touches on some of this diversity of current research.

  The La Playa archaeological site (SON F:10:3), in Sonora, Mexico, preserves 12,000 years of human utilization and occupation. Geologically, the site is characterized by a homogenous silt (Holocene?) overlain in places by a thin layer (2–6 cm) of cultural artifacts (ceramics and groundstone). This artifact layer is overlain by interbedded silts and cross-laminated and rippled, sands. The goal of the study was to map the distribution of the artifact layer and overlying sediments to determine: (1) if the layer is a lag deposit resulting from deposition and concentration of artifacts by fluvial processes; or (2) if it is a cultural layer and represents an earlier occupation that was subsequently buried. Results show that the artifact layer is confined to a 0.4 km2 area of the site and dips to the southwest at approximately 0.5°, which is consistent with the slope of the current topographic surface. The artifact layer is a cumulative palimpsest that reflects the mixing and concentration of artifacts from multiple occupations. The artifact layer was subsequently buried by sediments deposited by fluvial processes after A.D. 150 as indicated by the presence of Trincheras period ceramics.

  The La Playa archaeological site is located along the Rio Boquillas, north of Trincheras in northern Sonora, Mexico. The site contains an extensive record of human occupation beginning during the Paleoindian period with the most intense utilization of the site during the Early Agricultural period (3,700–1,900 cal BP). This work focused on detailed mapping and description of the stratigraphic units across the site. The oldest exposed stratigraphic unit is a reddish, sandy paleosol. The paleosol grades laterally into gravels that contain cobble-size clasts of diverse compositions. Overlying the paleosol is a tan-brown, homogenous silt (Holocene?) that lacks sedimentary structures and is consistently 98% silt and clay and 2% very fine sand. The paleosol and associated gravels were deposited during relatively wet conditions. The gravels are evidence of alluvial channels traversing the landscape and the composition of these gravels indicates significant transport distance based on the occurrence of nonlocal lithologies. The paleoenvironmental interpretation for the overlying silt has been considered a cienega deposit, but the silt has many characteristics in common with eolian deposited loess. An alluvial floodplain interpretation is feasible if the channel of the Rio Boquillas was stable and did not frequently avulse, allowing deposition of these fine-grained deposits.

  We explore the transformation of a site into a place of remembrance by evaluating the life history of an urnfield at Cerro de Trincheras, Sonora, Mexico. Prehispanic inhabitants used this cemetery as a cremation burial ground ca. AD 1300–1450. Memory of the cemetery persisted into historical times among inhabitants of the area, but its use changed. We argue that critical and contextualized approaches to cemeteries are needed to understand the complexity of how burial spaces are used through time.

  Occlusal surface wear scores were examined in a sample of 200 Formative period (1500bc-ad500) skeletons from the lower Azapa Valley in northwest Chile. Wear rate and plane (angle) were additionally evaluated using a subsample of paired first and second mandibular molars. The Formative period represents the transition from marine foraging to agro-pastoral dependence in the region, and differences in oral pathology indicate that diet varied by site location (coast vs valley interior) but not by archaeological phase (early vs late). We predicted that occlusal wear would demonstrate similar patterns, resulting from differences in food consistency, and therefore hypothesised that in coastal groups consuming greater quantities of foraged foods, occlusal surfaces should wear faster and exhibit flat molar wear, whereas among valley interior groups consuming greater quantities of agro-pastoral products, these should wear slower but exhibit more angled molar wear. Heavier posterior tooth wear was identified among coastal residents, but rate and angle of molar occlusal attrition did not differ significantly by location. Heavier overall wear and a steeper molar wear plane were identified during the early phase indicating that food consistency varied somewhat over the course of the Formative period. Overall, the results indicate that, although limited differences in tooth wear exist by site location, wear varied more over time likely reflecting a gradual transition from foraging to agro-pastoral dependence in the lower Azapa Valley. Although oral health indicators point to differences in dietary investment by location, maintenance of a mixed subsistence economy likely sustained a comparative consistency of foodstuffs.

  La Playa archaeological site in northern Sonora, Mexico contains a long record of human activity that includes the Paleoindian period (terminal Pleistocene) and much of the Holocene. The size and complexity of La Playa has discouraged a systematic characterization of its stratigraphy and geochronology, a deficiency we redress in the study. We distinguished seven stratigraphic units ranging in age from >44,570 to 400 cal yr B.P. using C-14 dates from charcoal and terrestrial gastropods found mostly in archaeological features. All of the buried (in situ) cultural remains are contained in Units B (4690-1580 cal yr BR) and C (1010-400 cal yr BR) and represent overbank deposition from the nearby Rio Boquillas. Occupation at the site peaks in Units B-4 and B-5, corresponding to the Cienega phase (2800 1800 cal yr B.P.) of the Early Agricultural period. This period coincides with the growth of early agricultural villages in the region and is marked at La Playa by thousands of archaeological features including roasting pits, human burials, and extensive canal irrigation systems. The presence of semi-aquatic and aquatic snails demonstrates that water was present year round in the canal systems constructed during this period. Stable and radiometric isotopic evidence suggests that early agriculturalists diverted ground water over several kilometers from the nearby Rio Boquillas. The extensive Cienega phase occupation ended after about 1700 cal yr B.P. with deep erosion of the site, an event also visible in alluvial records in southern Arizona that marked the end of the Early Agricultural period and significant changes in settlement organization in the region.

  Pueblo Grande de Nevada, more popularly known as “Lost City,” refers to a loosely defined series of archaeological sites in the Moapa Valley of southern Nevada. Excavated between the years of 1924 and 1941, these sites were to have a major impact on early-twentieth-century Southwestern archaeology. Despite the excitement that surrounded these finds at the time of their discovery, their legacy has largely been forgotten today. We argue one reason for this oversight is that the data obtained by the original researchers are inadequate for addressing the questions being asked of the region today. In particular, because plant and animal remains were not systematically recovered by the original researchers, the early fieldwork has provided only a broad sketch of the subsistence activities practiced in the region. To remedy these shortcomings, in 2006 archaeologists from the University of Nevada Las Vegas conducted additional excavations at House 20, a roomblock located within one of the so-called Lost C...

  This research considers the long-term relationship between women’s oral health and the transition to agriculture by examining dental caries and tooth loss in a prehistoric skeletal sample. Archaeological research indicates that women in many early agricultural communities experienced more severe dental pathology than male counterparts. Dentition was examined in an Early Agricultural skeletal sample from the La Playa site in Sonora, Mexico. Frequencies of caries and antemortem tooth loss (AMTL) were analyzed to test the hypothesis that in an early agricultural population undergoing major cultural changes, females experienced increased oral disease burden due to changes in the oral microenvironment resulting from greater reproductive stress. Adult females and males had similar caries rates, however, there were significant sex-differences in AMTL (p = 0.02). Comparisons across age groups indicate that La Playa women had substantial increases in AMTL, losing considerably more teeth than men. These findings, in light of dental research on oral health and pregnancy, provide an important temporal component to understanding the evolution and history of oral health and agriculture. The results suggest a dynamic process in the development of oral health trends as a function of the shift to agriculture and the burden of increased childbearing that females undertook during this transition. Key words: Oral health, tooth loss, pregnancy, agriculture.
