Intra-skeletal variability in trace elemental content of Precolumbian Chupicuaro human bones: the record of post-mortem alteration and a tool for palaeodietary reconstruction

This study applies an intra-skeletal sampling strategy to examine post-mortem alteration of archaeological human bone from west Mexico, and to reconstruct ancient diet. Human bone from the Chupicuaro culture (Mexico, Preclassic period) constitutes an ideal material with which to examine subsistence strategies because the specific hydrothermal environment in which the population lived would have provided certain food components (hydrothermal waters and carbonates) with distinct signature in Ca, Mg, F, Li, Sr, Mn, V and U values. Four to ten samples were taken from the long bones of six skeletons. Bone trace element content (Ca, P, F, Mn, Mg, Na, Li, V, Zn, Rb, Sr, Ba, Y, La, Ce, Nd, Th, U) and bone alteration parameters (crystallinity, organic matter and secondary calcite content) were analysed at the intra-skeletal level. Stable isotopic signatures (bone δ¹³C and δ¹⁸O_carbonate) and histological analyses were also performed on a single bone from each individual. Results indicate that all of the skeletons were affected by post-mortem mineralogical, structural and geochemical transformations. Biological bone δ¹³C values seem preserved for most of the individuals but an increase in crystallinity accompanies depletion in bone δ¹⁸O values. The combination of bone alteration parameters with bone elemental content shows that in this very specific context, a widespread dissolution-recrystallisation is unlikely. Of the hydrothermal tracers, Sr, F and Li were of particular interest because their retention in living tissues is related to the amount ingested. The intra-skeletal Li content does not reveal any pattern but Li depletion is not excluded. In contrast, Sr and F show a progressive intra-skeletal diagenetic enrichment likely due to gradual diffusion–adsorption processes. The bones with the lowest concentrations in these elements are assumed to yield the best representative ante-mortem values. The signal extracted from each skeleton, a very unusually high bone Sr, F and Li content, is interpreted as reflecting the consumption of the local hydrothermal products, which are also enriched in these elements.     

Chemical changes in buried animal bone: Data from a postmedieval assemblage

Macroscopic chemical analysis of animal bone recovered from dated excavation contexts of known pH from Castle Bromwich Hall, West Midlands, UK, allows an assessment of the rate and effects of bone decomposition, and the evaluation of current models of chemical decay. The results show great variation, and it is suggested that factors such as mechanical disturbance have a more significant effect on the differential destruction of excavated bone assemblages than chemical decay. The implications of this conclusion for the attempted reconstruction of past faunas, diet and behaviour are summarized, recommending caution in the acceptance of assemblages as unbiased samples.     

Women's Participation in Prehistoric Warfare: A Central Illinois River Valley Case Study

Considerations of Native American warriorhood are likely to conjure images of male‐bodied, masculine individuals. While the majority of formally recognized warriors may have indeed fit this mould, it is also true that female‐bodied/feminine warriors have been historically documented in many places, including North America. Further, even in cases where women were not formally recognized as such, it seems likely that they played offensive and defensive roles on an ‘as needed’ basis, such as on subsistence outings or when their homes and families were under attack. In this paper, we seek to explore the intersection of womanhood and warfare‐related violence at Morton Village (11 F2) and the associated Norris Farms #36 cemetery. This late prehistoric community in the Central Illinois River Valley has been the subject of extensive bioarchaeological interest regarding high levels of skeletally indicated violent trauma. We review this osteological evidence in addition to incorporating mortuary and subsistence perspectives on the ideology and practice of warfare at this time and place. A tripartite approach considering osteological trauma patterns, mortuary commemoration, and new interpretations of community life leads us to suggest an alternate interpretation—one in which Morton Village women are, in at least some instances, considered as active defenders of their community and lifeways rather than passive victims of violence.

Mississippian Habitation Components at Dickson Mounds in the Central Illinois River Valley

The Myer-Dickson area is a habitation component of the well-known Spoon River Mississippian mortuary site Dickson Mounds. About 20 domestic and public buildings were excavated at the site in the 1960s and 1970s, including the second-largest Mississippian building known in Illinois. Though sometimes characterized as a nucleated village, detailed analysis of material remains and their spatial distribution suggests two and possibly three periods of use during the Larson phase between A.D. 1200 and 1300. The large public building is one of several structures bordering a plaza, all of which are almost totally devoid of Mississippian artifacts. Domestic use of other sections of the site during the late Larson phase is part of a broader pattern of dispersed settlement on valley-edge ridges, a pattern that indicates at least some periods when fears of raiding were lessened despite the presence of contemporaneous palisaded towns.     

Microdictyon plates from the lower Cambrian Ajax Limestone of South Australia: Implications for species taxonomy and diversity

A small assemblage of isolated Microdictyon plates is described from the lower Cambrian Ajax Limestone, Mt Scott Range (Flinders Ranges), South Australia. Microdictyon plates are primarily known from single, isolated, perforated phosphatic sclerites; only one species (M. sinicum) from the Chengjiang Lagerstätte is known from soft-bodied preservation of the complete organism. The isolated plates from South Australia display a wide range of morphologies potentially reflecting: 1, considerable diversification within the group at this time; 2, extensive intraspecific morphological variation; 3, different plate morphotypes along the trunk of the animal; or 4, significant ontogenetic variation in successive growth stages. The South Australian specimens are similar to several individual sclerites described from other Cambrian palaeocontinents, but appear closest to faunas described from South China. Problems associated with the taxonomy of isolated Microdictyon plates are discussed, including the lack of knowledge associated with intraspecific and/or ontogenetic variability and how individual plate morphology may relate to size or relative position along the length of the complete organism.     

An Interdisciplinary Human-Environmental Examination of Effects Consistent with the Anthropocene in the Lower Illinois River Valley

Using archaeological and ecological data of animal communities, and fish communities in particular, we test for evidence consistent with the Anthropocene in the lower Illinois River valley across millennia. Environmental impacts by preindustrialized peoples may be minor compared to current alterations; however, this hypothesis is untested and should be assessed. Using the relative abundance of fish taxa, we tested for differences among archaeological and modern time periods, taking advantage of published zooarchaeological data sets and newly analyzed data. Collections from all archaeological time periods differed significantly from modern collections, but the relative abundance of fishes did not differ significantly among archaeological time periods. Sociopolitical context, material culture, plant-based subsistence patterns, and the use of animal classes shifted temporally, but these differences did not extend to the relative abundance of fish families. Our results suggest that dominating human influences on fish communities did not occur prior to the Late Woodland period in the lower Illinois River.     

Morphometric Analysis of Sus Remains from Neolithic Sites in the Wei River Valley,China, with Implications for Domestication

Size variation of Sus remains within and between sites is examined for the Neolithic sites in the Wei River valley in China. The coefficient of variation [V] for pig measurements at the sites of Wayaogou, Quanhucun and Jiangzhai was calculated, and we observed patterns that show evidence of two populations of different‐size pigs, supporting the likelihood that both wild and domestic pigs were present. Also, size reduction of pigs can be traced within the Neolithic‐early Bronze Age archaeo‐faunal sequence of the Wei River valley. This size reduction was accompanied by an increase of coefficients of variation through the Neolithic. Both of these trends were probably the consequences of pig domestication, and the morphometric differences probably provide evidence for the different stages of pig domestication in this region.

The Late Roman Landscape of the Northern Levant: A view from Tell Qarqur and the lower Orontes River Valley

This paper presents a review and synthesis of archaeological surveys in western Syria and southern Turkey, alongside finds from recent excavations at Tell Qarqur, Syria, revealing regional patterns of late Roman settlement and land use in the lower Orontes River Valley. Survey data show that the late Roman period witnessed a peak in settlement density, with the extension of occupation into previously unoccupied areas and widespread agricultural intensification. Excavations of a typical lowland site at Tell Qarqur reveal an opulent building complex, possibly a church, with a columned hall, elaborate mosaic floor and frescoed interior. Analysis explores the process of agricultural intensification during the late Roman period, the relationship between lowland settlements and the better‐known Dead Cities of the limestone massif to the east, and the ultimate abandonment of the settlement system following the seventh century AD.     

Timber and Town: Post-War Federal Forest Policy, Industrial Organization, and Rural Change in Oregon's Illinois Valley

In the recent political furor over disposition of the remaining old-growth forests in the Pacific Northwest, focus has been directed at the ecological shortcomings of the federal sustained yield forest management doctrine. This has occurred in part at the expense of evaluation of these policies based on social criteria. Yet the sustained yield paradigm and the post-war compact between private capital and federal forest agencies were justified in part to foster stable rural timber economies. Nowhere has this compact been more significant than in rural Oregon. And yet nowhere are its failings more apparent. The central argument of this paper is that the failure of federal sustained yield policies to sustain rural communities stems from an implicitly naive model of industrial capitalism. By ignoring the inherently destabilizing character of capitalist industry, by further failing to refine the notion of community stability, and by failing to take genuine steps to defend rural society from the upheavals of industrial change, the United States Forest Service and the Bureau of Land Management have allowed community stability to languish in the dogged pursuit of accelerated cutting rates. This paper explores industrial change in Oregon's forest products sector in the post-war era of federal sustained yield management, looking specifically at southwest Oregon's Illinois Valley.     

Evidence for Interaction from Recent Hunter-Gatherer Sites in the Caledon Valley

Evidence for contact between hunter-gatherers and agropastoralists from excavated sites in a well-documented frontier zone in the eastern Free State, South Africa, reveals varied intensities of interaction. These interactions range from clientship to relative autonomy. Comparison between recent (eighteenth- to early twentieth-century) hunter-gatherer occupations of rock shelters in the Caledon Valley also suggests that a variety of social relationships between hunter-gatherers and farmers, known ethnographically, occurred simultaneously.     

Stable isotope evidence for salt-marsh grazing in the Bronze Age Severn Estuary,UK: implications for palaeodietary analysis at coastal sites

Stable isotope analyses of modern coastal and salt-marsh plant species (‘salt-loving’ plants or halophytes) have demonstrated that these are significantly enriched in ¹⁵N compared to other terrestrial plants. Coastal salt-marshes were far more extensive in the past than they are today. They represented a vast and much-exploited resource in many areas of the UK and north-western Europe and were considered to be prime land for the grazing of animal stock.     

The origins and development of complex prehispanic society in the Lower Santa Valley,Peru: Implications for theories of state origins

A major issue in attempts to construct cross-culturally valid theories of state origins is the relative roles of irrigation agriculture, population growth, and warfare in the rise of complex society. Recently, data from the coast of Peru has provided the stimulus for the formulation of the “coercive theory” of state origins. This theory proposes that state formation in circumscribed environments was the result of population pressure, internecine (local level) warfare, and the incorporation of defeated groups into ever larger, victorious polities. Yet, although the pioneering study of settlement patterns was carried out in Virú Valley, the lack of a comprehensive regional study of the development of prehispanic subsistence-settlement systems in any Peruvian coastal valley meant that the “coercive theory” rested on a precarious data base. Selected results of an extensive and systematic survey carried out in 1979–1980 in the Lower Santa Valley, an area only partly studied prior to our research but long famous for its large number of major prehispanic walls and fortresses, are discussed. Following a discussion of the problem, research methods and data for the early periods leading to state formation are outlined. Analysis of settlement patterns, maize-based carrying capacity, and settlement-cluster ceramic assemblages is then carried out to suggest refutation of the “coercive” model and acceptance of an alternative model of multivariate causality. External, or intervalley, warfare is shown to have been an important socioenvironmental stress leading to sociocultural complexity not only in Santa, but probably in adjacent valleys as well.     

The Saharan divide in the Nile Valley: the evidence from Qasr Ibrim

Recent research at Qasr Ibrim in Egyptian Nubia shows that, during the last 3000 years, this hill-top site commanding a long stretch of the Nile in the First Cataract region was usually controlled by polities centered further to the south — Napatan, Meroitic and Christian. Even when controlled by northerners — Greek, Roman or Turkish — is was still a frontier post. It is suggested that this evidence, showing that the frontier between the states dominating the Lower and Middle Nile was located as far north as the First Cataract, helps explain the lack of Mediterranean influence in the Upper Nile basin and, beyond, in sub-Saharan Africa. The Nubian Corridor was, in fact, blocked so far north that it is best described as a cul de sac.

Résumé Les recherches menées à Qasr Ibrim dans la Nubie égyptienne ces dernières années montrent que ce site, qui domine du sommet d'une colline une partie assez grande du Nil dans la région de la première cataracte, a été controlé pendant les trois derniers millénaires par une série de royaumes dont les centres se situaient plus au sud — royaumes de Napata et Meröe, royaume chrétien. Qasr Ibrim restait un poste frontière même quand il passait sous contrôle des peuples du nord — grecques, romains ou turques. Ces données, qui montrent que la frontière entre les royaumes qui dominaient le bas Nil et ceux qui dominaient le moyen Nil se trouvaient très au nord jusqu'à la première cataracte, peuvent nous aider à comprendre l'absence d'influences méditerranéennes dans le bassin de l'haut Nil et au délà, dans l'Afrique au sud du Sahara. A vrai dire, le coloir nubien était barré autant au nord qu'il mérite d'être considéré plutôt comme une impasse.

     

Radiocarbon reservoir effects in human bone collagen from northern Iceland

Human bone collagen from a series of Icelandic human pagan graves was radiocarbon (¹⁴C) dated to aid understanding of early settlement (landnám) chronologies in northern Iceland. These individuals potentially consumed marine protein. The ¹⁴C age of samples containing marine carbon requires a correction for the marine ¹⁴C reservoir effect. The proportion of non-terrestrial sample carbon was quantified via measurement of carbon stable isotopes (δ¹³C) using a simple mixing model, based on δ¹³C measurements of archaeofaunal samples. Non-terrestrial carbon was also quantified in six pig bones from the archaeofaunal dataset. Assuming all non-terrestrial carbon in human and pig bone collagen was marine-derived, calibrated age ranges calculated using a mixed IntCal09/Marine09 calibration curve were consistent with an early settlement date close to landnám, but several samples returned pre-landnám age ranges. Measurements of nitrogen stable isotopes (δ¹⁵N) strongly suggest that many of the human bone collagen samples contain freshwater diet-derived carbon. Icelandic freshwater systems frequently display large freshwater ¹⁴C reservoir effects, of the order of 10,000 ¹⁴C years, and we suggest that the presence of freshwater carbon is responsible for the anomalously early ages within our dataset. In pig samples, the majority of non-terrestrial carbon is freshwater in origin, but in human samples the proportion of freshwater carbon is within the error of the marine component (±10%). This presents a major obstacle to assessing temporal patterns in the ages of human remains from sampled graves, although the majority of grave ages are within the same, broad, calibrated range.     

Practical Application of Digital Photogrammetry for Fieldwork in the American Midwest: An Example from the Middle Ohio Valley

The use of close-range digital photogrammetry for field documentation has been steadily increasing in the past half decade in several parts of the world. However, this technology has not been widely utilized in archaeological contexts in the American Midwest. We explore the utility of close-range photogrammetry in this region with examples from the Guard site (12D29), a Fort Ancient village located in southeastern Indiana. This article outlines the methods utilized for production of georeferenced 3-D models of several units excavated during the 2016 field season. These models as well as plan and profile orthophotos derived from them act as important supplements to standard photographs and drawings made in the field and easily integrate with the site GIS. Overall, we found close-range digital photogrammetry to be very useful to better document excavation details, doing so for limited cost and time expenditure.
