Radiocarbon dating of marine shell samples. The marine radiocarbon reservoir effect of coastal waters off Atlantic Iberia during Late Neolithic and Chalcolithic Periods

Radiocarbon dates on marine shells have not been used as extensively as charcoal or bone dates for the setting up of absolute chronologies because interpreting these dates is complicated by the marine radiocarbon reservoir effect. Nevertheless marine shellfish were used widely at least during the Holocene and their shells are abundant and usually well preserved in archaeological deposits located near shorelines. Consequently prior research concerning the oceanographic conditions and the marine radiocarbon reservoir effect of a particular coastal area is needed in order to set up reliable chronologies for that region. Values of regional marine radiocarbon reservoir effect – ΔR – of coastal waters off Atlantic Iberia, some of its variability along the Holocene and its correlation with the upwelling phenomenon were determined during previous research. More data related to the ΔR values for western Portuguese coastal waters during the Late Neolithic and the Chalcolithic, a time interval badly sampled in previous research, were recently obtained. These values can be compared with ΔR values already determined for the Gulf of Cadiz. Besides the importance of these values for a better knowledge of the palaeoceanography and palaeoclimatology of Atlantic Iberia, from now on archaeologists can set up reliable chronologies for Late Neolithic and Chalcolithic contexts using marine shell samples of that origin for radiocarbon dating.     

The Seaweed FlyThoracochaeta zosterae(Hal.) (Diptera: Sphaerocidae) in Inland Archaeological Contexts: δC and δN Solves the Puzzle

The presence of the flyThoracochaeta zosteraein cesspits had led to the unlikely interpretation that seaweed had been present in Mediaeval cesspitis. Archaeological and modern pupae fromT. zosteraewere sampled along with their probable larval diets (extracted plant material from cesspit and seaweed, respectively). The spacing between pupae and food for δ¹³C and δ¹⁵N was similar for both modern and archaeological samples. Modern pupae had isotopic ratios typical for marine invertebrates for δ¹³C. Archaeological puparia had isotopic values typical for terrestrial grazers (i.e., non-marine), indicating that there was no marine inclusion in the cesspits.     

A Late Holocene vertebrate food web from southern Haida Gwaii (Queen Charlotte Islands, British Columbia)

This study presents isotopic data (δ¹³C and δ¹⁵N from bone collagen) for 104 samples representing 29 vertebrate taxa from late pre-contact through to contact era (ca. 2000 – 100 BP) Haida Gwaii (British Columbia, Canada) from a wide variety of mostly marine organisms. The results demonstrate the considerable isotopic variability that characterizes potential prey items in coastal contexts and underscores the need for baseline faunal data to interpret human subsistence practices. Based on these data, a detailed marine food web was constructed, which provides insight into local ecological conditions. We present a simple method for quantifying the trophic level of ancient fauna using δ¹⁵N of bone collagen. Finally, we discuss the implications of this study for the reconstruction of human diet.     

Coast–inland mobility and diet in the Danish Mesolithic and Neolithic: evidence from stable isotope values of humans and dogs

Here we present the stable isotope ratios of carbon and nitrogen measured in bone collagen extracted from humans, dogs, herbivores and fish from Mesolithic and Neolithic coastal and inland sites in Denmark. Bones of freshwater fish from several Early Mesolithic lake-side sites have δ¹³C values surprisingly similar to those seen in marine fish. We propose a model, based on δ¹³C and δ¹⁵N, for the correction for both marine and hard water reservoir effect in radiocarbon dates. A strong reliance on aquatic protein is demonstrated for the Mesolithic inhabitants of the region from the middle of the Early Mesolithic onwards. A significant part of the protein in the diets of the dogs and humans from the Middle and Late Mesolithic was of marine origin, even at inland sites. This observation points to a high degree of (seasonal) coast-inland mobility. The isotopic evidence indicates that during the Neolithic small quantities of aquatic foods were still common sources of dietary protein.     

‘Faites le mien desir’: studious persuasion and baronial desire in Jordan Fantosme's Chronicle

This article examines the remarkable ‘changes and transpositions’ of form found in Jordan Fantosme's Chronicle, an important Anglo-Norman estoire recounting the rebellion against Henry II in 1173–74. By reading these literary changes as accommodations of circumstances and persons, they can be used to locate the Chronicle in very specific historical and social contexts. Jordan, clerk of the bishop of Winchester and master of the city's grammar schools, places himself, both socially and discursively, within a community of administrative barons, who are very carefully remembered in the Chronicle as a coherent social affinity, or foedus amicitiae, both alienated from and seeking solidarity with the king. These conditions explain the Chronicle's central rhetorical impulses: to chastise the king, sometimes bitterly, and to persuade him to ‘love, cherish … and reward’ these specific barons. To achieve these rhetorical desires, Jordan draws upon the resources of contemporary literary education to imagine and perform persuasion. The Chronicle is thus a powerful illustration of John Baldwin's account of the ‘interpenetration’ of studium et regnum, institutional learning and political administration, in twelfth-century England. Because the Chronicle has in the past been understood as a panegyric, or even propaganda, for a royalist cause, this baronial reading represents a major re-assessment of its sociabilities and purposes.     

Space and social control in the administration of the Oglala Lakota ("Sioux"), 1871-1879

The "panoptic" logic of social control analyzed by Michel Foucault plays an important part in regulating "normal" citizens of the modern world as well as institutionalized populations. However, control of the unconfined presupposes certain conditions not paid adequate attention by Foucault, especially the requirement that people be individually identifiable in most activities, and that private property be located at fixed addresses. In order to explore the importance and the implications of these and other preconditions, this paper examines the strategies with which the U.S. government attempted to bring the Oglala Lakota under administrative control during the first decade of their settlement around the Red Cloud Agency on the northern Great Plains. Oglala society exhibited none of the hypothesized prerequisites for social control by the U.S. government at the beginning of the decade, but by 1879, the rudiments of a working system were in place. This story of the struggles surrounding its imposition robs modern social control of its seeming naturalness and immutability, brings into a critical light many of the spatial conditions we take for granted in today's world, and suggests the importance of a new, relatively unexplored dimension of the historical geography of American Indians and their dealings with White society.To the men of my time was appointed the task of taking the raw and bleeding material which made the hostile strength of the plains Indians, of bringing that material to the mills of the white man, and of transmuting it into a manufactured product that might be absorbed by the nation without interfering with the national digestion…In the language of the bounding West in which he made his habitat, it may be said that, in 1871, the Indian was "halter-broke but he had not yet been bitted".James McLaughlin,Former Agent to the Standing Rock Sioux     

Stability in the South Pacific surface marine C reservoir over the last 750 years. Evidence from American Samoa, the southern Cook Islands and the Marquesas

Although minor climatic and sea-level changes have been documented for the South Pacific during the late Holocene, our understanding of the consequent impact of these changes on the marine ¹⁴C reservoir, and therefore the ¹⁴C content of shellfish, is limited. Ultimately, this has implications for documenting the chronology of human movement and adaptation in this region. In this paper we compare marine reservoir (ΔR) data obtained from tightly controlled archaeological proveniences with known-age, pre-AD 1950 shells from the southern Cook Islands, American Samoa, and Marquesas Islands. Results indicate that there has been no significant change in the near-shore marine reservoir in these three locations over the last ca. 750 years. Furthermore, known-age, pre-AD 1950 shell samples provide more precise ΔR values for use in sample calibration than archaeological paired shell/charcoal samples. This is attributed in part to the limitations of assigning provenance and age to material from archaeological sites. On the basis of these results we conclude that the known-age, pre-AD 1950 shell derived ΔR values can be used to calibrate shell ¹⁴C results from deposits of late Holocene age.     

Welsh Indians and savage Scots: History, antiquarianism, and Indian languages in 18th-century Britain

This paper compares late eighteenth-century claims for the authenticity of Macpherson's Ossian and for the existence of Welsh Indians. It shows that although both claims were supported in part by appeals to similarities between Celtic and American Indian languages, the appeals in each case were very different. On the one hand, the Edinburgh literati who supported Ossian's authenticity focused on expressive structures shared by all primitive societies. On the other hand, radically Protestant antiquarians and philologists focused on lexical similarities that they argued demonstrate a genetic link between certain American Indians and the Welsh. The paper uses this fundamental difference underlying a superficial similarity, to explore in greater detail the distinction between philosophical historians among the Edinburgh literati, who were religiously moderate, politically conservative, and promoted Scotland's integration into a modern, polite, commercial and English-speaking empire, and the Welsh antiquarians, who were religious and political radicals and whose interest in the Welsh Indians reflected and reinforced their attempts to resurrect a distant golden age of Celtic Britain.

Same island, different diet: Cultural evolution of food practice on Öland, Sweden, from the Mesolithic to the Roman Period

The Mesolithic–Neolithic transition in north-west Europe has been described as rapid and uniform, entailing a swift shift from the use of marine and other wild resources to domesticated terrestrial resources. Here, we approach the when, what and how of this transition on a regional level, using empirical data from Öland, an island in the Baltic Sea off the Swedish east coast, and also monitor changes that occurred after the shift. Radiocarbon dating and stable carbon and nitrogen isotope analyses of bones and teeth from 123 human individuals, along with faunal isotope data from 27 species, applying to nine sites on Öland and covering a time span from the Mesolithic to the Roman Period, demonstrate a great diversity in food practices, mainly governed by culture and independent of climatic changes. There was a marked dietary shift during the second half of the third millennium from a mixed marine diet to the use of exclusively terrestrial resources, interpreted as marking the large-scale introduction of farming. Contrary to previous claims, this took place at the end of the Neolithic and not at the onset. Our data also show that culturally induced dietary transitions occurred continuously throughout prehistory. The availability of high-resolution data on various levels, from intra-individual to inter-population, makes stable isotope analysis a powerful tool for studying the evolution of food practices.     

Opportunistic versus target mode: Prey choice changes in central-western Korean prehistory

Human decision-making processes are usually hierarchical in that higher-level decisions impose constraints on lower-level decisions. As a result, prey choices during individual foraging trips are governed to a large degree by higher-level decisions regarding how to supply resources to satisfy demands, with higher-level decisions typically made prior to foraging trips. Resource selectivity and search bias sometimes take place in this context. By dividing resource procurement modes into opportunistic and target, I discuss how choice of mode on the basis of an overall economic plan affects prey choice during foraging trips and faunal assemblage composition resulting from those trips. An analysis of taxonomic diversity in shellmidden assemblages from the central-western Korean Late Chulmun Period (3500–1300 BC) and Middle and Late Mumun Period (700–100 BC) shows that Late Chulmun people adopted a target mode, while Middle/Late Mumun people adopted an opportunistic mode in their exploitation of marine resources. A decrease in the importance of marine resource in Middle/Late Mumun produced a change in taxonomic diversity by increasing the opportunistic cost of marine resource exploitation.     

A COMPARATIVE SCIENTIFIC STUDY OF THE EARLIEST KILN SITES OF KORYǑ CELADON*

Four of the Koryǒ dynasty's earliest kiln sites are studied for the macroscopic, compositional, and microstructural characteristics of their celadon products. Recent excavation of Sǒri and surface investigation of Kangjin sites provided new materials for closer examination of the origin and early developments of celadon technology in traditional Korea. Two other sites, Wǒnhǔngni and Osari, with archaeological characteristics in common with the oldest layer of Sǒri, are also examined. Principal component analysis of body composition shows thai Sǒri and Kangjin had better control in their choice of raw materials whereas Wǒnhǔngnt and Osari had much wider scatter, showing the more experimental nature of their operation. The early Kangjin grouped out separately primarily because of their higher Al₂O₃ content, while X-ray diffraction patterns indicate they might have been fired at a higher temperature than other groups. The Korean method of two-step firing, first at a lower temperature to bake imglazed bodies and then at a higher temperature after glazing, is evident from the earliest operations in Kangjin.     

PROVENANCE STUDIES OF KOREAN CELADONS OF THE KORYǑ PERIOD BY NEUTRON ACTIVATION ANALYSIS*

Neutron activation analyses of the body fabric of celadons from the main production sites of the Koryǒ period have shown differences in composition between kilns. Comparison of over 50 celadon objects in the collections of the British Museum with this data base from the production sites has permitted the assignment of over 40 of the pieces to their kiln of origin The majority show the trace element pattern of the Sadangri kilns, a smaller proportion are assigned to Yuchǒnri, while others are assigned to the kilns at Chinsanri (underglaze iron) and Kyǒngsǒ-dong (unglazed). A representative group of Chinese Yue wares arc clearly different from Koryǒ celadons in trace element composition.     

‘Fighting from the fields’: developing the British ‘National Farm’ in the Second World War

The Second World War had a profound impact on British Agriculture, with state intervention at an unprecedented level cementing the idea of a ‘National Farm’ in both the popular and the governmental psyche. Critical attention has recently begun to refocus on this period, adding to the somewhat celebratory meta-narratives written in the official histories. Drawing from the practice of micro-historical research and recent work in geography that seeks to understand the production of the landscape ‘from within’, this paper explores how ‘small stories’ can afford an appreciation of the ‘complications of everyday existence’ and bring greater depth, nuance and understanding to these ‘larger’ historical events and their influence on the British countryside. Utilising oral histories from farms in Devon (UK), the paper explores the micro-geographies which shaped as well as destabilised the national farm message as it was translated into the local context.

Using foraminifera to distinguish between natural and cultural shell deposits in coastal eastern Australia

Foraminifera are single cell protozoa that are ubiquitous in marine environments. Although the hard casings, or tests, of foraminifera are routinely studied in the earth sciences, they have been little studied by archaeologists, despite their potential to contribute to understandings of coastal site formation processes and palaeoenvironments. In this study techniques and methods of foraminiferal analysis are developed and applied to the problem of distinguishing between natural and cultural marine shell deposits, using the Mort Creek Site Complex, central Queensland, Australia, as a case study. Results allow separation of natural and cultural deposits based on foraminiferal density. Natural deposits were found to have >1000 foraminifera per 100 g of sediment, while cultural deposits exhibited <50 foraminifera per 100 g of sediment. Results allow us to better understand site formation processes at the Mort Creek Site Complex and highlight the potential of foraminiferal analyses in the interpretation of terrestrial marine deposits.     

Unique marine taphonomy in human skeletal material recovered from the medieval warship Mary Rose

The effect of skeletal exposure in a marine environment is an area of taphonomy that has been little investigated at the microscopic level. Understanding the peri‐mortem and subsequent post mortem history of deposition and/or redeposition is extremely important for event reconstruction and to identify deliberate or accidental redeposition. The material used for this study comes primarily from the Mary Rose shipwreck (a marine mass fatality dated AD 1545), and forensic material recovered from marine, lacustrine and terrestrial contexts is retrospectively referenced. Work presented here outlines a definitive type of marine exposure seen in temperate shallow off‐shore and intertidal marine contexts, and illustrates how it may be differentially identified from terrestrial deposition and exposure. Furthermore, the effects of rapid deposition on skeletal remains have been documented, and results indicate that marine organism fouling activity can be fully inhibited by rapid deposition of sediment. The responsible organism itself remains unidentified, but produces tunnels which are peripheral in their distribution and maintain fixed dimensions and morphology and are here associated with marine exposure. This type of microstructural change is unique and is not found in terrestrial or freshwater contexts. The study demonstrates a taphonomic microstructural change to bone and teeth which may be identified microscopically and interpreted as evidence of marine exposure. Secondarily, the history of depositional exposure between the two main Tudor layers has provided a new level of detail concerning exposure and site formation processes. The earliest Tudor layer formed rapidly over a period of months and contained no evidence of microstructural tunnelling, whereas microstructural tunnelling was seen exclusively in the second Tudor layer, formed over a period of decades, a period during which the ship's hull collapsed and a more open marine environment dominated.

Variability in Faunal Assemblages: The Influence of Hunting Skill, Sharing, Dogs, and Mode of Cooking on Faunal Remains at a Sedentary Kalahari Community

Variability in faunal assemblages from different sites and/or from different time periods is often attributed to economic or taphonomic factors. The role of sharing on faunal remain distributions is compared to other factors that have been suggested to influence these distributions, such as hunting skill. Faunal species and skeletal elements are compared among three hunter—gatherer camps that form a sharing network. These are contrasted with those of two other hunter—gatherer camps located at the same Kalahari community occupied by an unusual family that is a relative isolate in terms of sharing. The effect of sharing on equalizing variation in hunting success as reflected in the faunal remain inventory is explored from the five camps inventoried in 1990. Complicating factors which tend to affect faunal remain frequencies are also examined, such as cooking technique and dogs. All faunal remains visible on the surface of each camp were recorded according to species, element or fragment portion, age (mature or immature), and, when possible, side. At all but one camp, surface faunal remains were recorded both before and after ethnographic observations during the dry season of 1990. In addition to hunting success, all occurrences of sharing and consumption of meat were recorded during these observation periods and those conducted on and off between 1987 and 1992. Although participation in a sharing network obscures differences in hunting skill in the archaeological record, sharing impacts on faunal assemblages in interesting ways that are potentially archaeologically visible. Sharing in strongly egalitarian societies levels unequal hunting skill that could otherwise affect faunal remain frequencies, taxa richness, meat weight, and other indices measured here. In these societies, sharing reinforces social bonding between kin and friends in ways that help unit families from different camps.Zooarchaeologists have become accustomed to high levels of confidence in their inferences about the origins, functions, and responses to stress of animal remains. This confidence rests on the causal and functional links between attributes of these remains and the processes and contexts which generate them. Their investigations are presently moving toward wider inferences about the context and functions of bones in ancient hominids' behavioral systems… Zooarchaeologists now need a different set of inferential strategies than that which characterized their preceding phase of research.

Probing dietary change of the Kwädąy Dän Ts'ìnchį individual,an ancient glacier body from British Columbia: II. Deconvoluting whole skin and bone collagen δC values via carbon isotope analysis of individual amino acids

The remains of the Kwäd?y Dän Ts'ìnch? individual, a frozen male human, were recovered from a retreating glacier within the Tatshenshini-Alsek Park in British Columbia in August 1999. In order to provide information on both the geographical origin of this individual and low long he spent in the remote interior region prior to his death, molecular analysis and compound-specific carbon isotope analyses were performed on individual amino acids purified from his skin and bone. Gas chromatographic quantification of constituent amino acids of both tissues revealed a molecular distribution characteristic of collagen, dominated by glycine and to a lesser extent proline, hydroxyproline and alanine. Chiral gas chromatography indicated that protein preservation in both tissues was exceptional. Carbon isotope analysis of a faunal assemblage from an earlier prehistoric site from southern British Columbia provided reference dietary amino acid δ¹³C values for terrestrial (deer and domestic dog) and marine species (salmon and sealion), showing clear separation in all amino acids, particularly glycine which was extremely ¹³C-enriched in the marine animals. The distinction between terrestrial and marine organisms was increased by exploring Δ¹³C_{Glycine-Phenylalanine} values (6.6 ± 0.6‰ and 15.0 ± 2.1‰, respectively), which were higher in the latter by approximately 8‰, mirroring the increased δ¹⁵N_{Bulk collagen} values observed for the marine animals (R² = 0.78; p < 0.001). The Kwäd?y Dän Ts'ìnch? individual's bone had a similarly elevated Δ¹³C_{Glycine-Phenylalanine} value of 15.6 ± 1.0‰, indicating his extreme reliance on marine dietary resources throughout early life. The skin amino acid δ¹³C values were consistently lower than those observed for bone, with a concurrently lower Δ¹³C_{Glycine-Phenylalanine} value of 12.7 ± 0.9‰. The shift between the carbon isotope composition of bone (long-term diet) and skin amino acids (short-term diet) confirmed a sudden divergence away from marine food sources in the last months of life, consistent with his discovery 80 km inland.     

Variability in the marine radiocarbon reservoir effect in Muscat (Sultanate of Oman) during the 4th millennium BC: reflection of taphonomy or environment?

Radiocarbon (¹⁴C) dating of archaeological coastal sites in arid areas is challenging because of the relative rarity of datable terrestrial artefacts. Marine artefacts provide an abundant source of carbon, which is technically easy to date but radiocarbon dates need to be corrected for local variations from the global average marine ¹⁴C reservoir age (ΔR). In archaeological sites, this is usually done by the comparison of the ¹⁴C age measured between coeval pairs of terrestrial and marine samples that have no inbuilt age. Here, we present the results of a study that aims to determine the local ¹⁴C marine reservoir effect (MRE) along the Eastern coast of the Arabic Peninsula during the 4th millennium BC, a period of important cultural, demographic and social changes in this region. Previous estimates of the MRE based on associated shells and charcoal vary by about 400 ¹⁴C yr and this is a serious limitation to the establishment of a precise chronology in the area based on marine material. In order to maximize the chances to obtain contemporaneous terrestrial–marine pairs for a new assessment of the MRE in this region we dated charcoal, shells, fish and turtle bones as well as human bones found in three recently and carefully excavated graves from Ra’s al-Hamra RH5. A large variability was found between charcoals (up to 240 ¹⁴C yr) and marine specimens (up to 785 ¹⁴C yr) present in the same grave. This variability was attributed to inbuilt ages, diagenesis and possibly environmental factors although taphonomic processes cannot be excluded. We discarded the oldest charcoals and used the ¹⁴C ages obtained on human apatite as a cut-off value to remove the marine outliers. Two out of the three graves provided terrestrial and marine assemblages which did not differ statistically and were used to calculate an average MRE of 645 ± 40 ¹⁴C yr (ΔR = 255 ± 55 ¹⁴C yr). This value is consistent with previous estimates based on the ¹⁴C dating of marine sediments off Pakistan and suggests stability of the MRE in the Arabian Sea since the 4^th millennium BC.
