TORKSEY AFTER THE VIKINGS: URBAN ORIGINS IN ENGLAND

In ad 872–3 a large Viking Army overwintered at Torksey, on the River Trent in Lincolnshire. We have previously published the archaeological evidence for its camp, but in this paper we explore what happened after the Army moved on. We integrate the findings of previous excavations with the outcomes of our fieldwork, including magnetometer and metal-detector surveys, fieldwalking and targeted excavation of a kiln and cemetery enclosure ditch. We provide new evidence for the growth of the important Anglo-Saxon town at Torksey and the development of its pottery industry, and report on the discovery of the first glazed Torksey ware, in an area which has a higher density of Late Saxon kilns than anywhere else in England. Our study of the pottery industry indicates its continental antecedents, while stable isotope analysis of human remains from the associated cemetery indicates that it included non-locals, and we demonstrate artefactual links between the nascent town and the Vikings in the winter camp. We conclude that the Viking Great Army was a catalyst for urban and industrial development in Torksey and suggest the need to reconsider our models for Late Saxon urbanism.

Constraining a bioavailable strontium isotope baseline for the Lake Garda region, Northern Italy: A multi-proxy approach

The evidence of prehistoric long-distance exchange networks in northern Italy is overwhelming, attested by several finds of non-local raw materials in Bronze Age pile-dwelling settlements of Lake Garda and eastern Po plain, like amber beads and bronze artefacts. Metals are dispersed throughout Bronze Age Europe from mining communities within the Alpine regions, and possibly local artefacts, like the Peschiera-type daggers, are known from archaeological records throughout Europe. This positions the region as part of organized networks of trade and communication connecting prehistoric Europe from north to south. This, however, does not in itself indicate a similar long-distance mobility of prehistoric individuals. To investigate individual, human provenance and mobility, the strontium (Sr) isotope methodology compares strontium isotope analysis of human remains to bioavailable strontium isotope baselines characterizing the regions of interest. We present here environmentally based, multi-proxy (water, soil leachates and plants) Sr baselines from the Lake Garda region. Our results show two separate baselines, roughly corresponding to the geographical distribution of rock types and erosional products thereof. One baseline is valid for the Lake Garda region, where Mesozoic carbonates are a dominant surface-near strontium source, and for the central Po plain north of River Po. We constrain this to 87Sr/86Sr = 0.7088 ± 0.0014 (2σ; n = 44) when including 9 compatible samples reported previously. The second Sr-baseline is valid for Alpine areas dominated by magmatic (basalts excluded) and metamorphic bedrock around the Fersina valley. We constrain this to 87Sr/86Sr = 0.7146 ± 0.0058 (2σ; n = 22) when including 11 compatible samples reported in previous studies. The baselines are compatible with previously reported results of other Sr proxies such as snails, archaeological fauna, and agricultural soils and products from the region.

Insights into the Roman diet from Herculaneum

Archaeology Both historical sources and standard stable isotope analyses of human remains have offered insights into patterns of food consumption in ancient Rome. However, this research is often not of a sufficiently high resolution to explore variations in diet between the sexes, in different occupations, or with more subtle degrees of social status. To address this shortcoming, Soncini et al. used a combination of stable isotope analysis of bone collagen with Bayesian models of protein synthesis of 17 adults who perished in the 79 CE eruption of Mount Vesuvius. They found that men consumed more fish than women, but in terms of total energy obtained, the diets of both sexes were dominated by cereals, terrestrial animals, olives, and possibly wine. Sci.

Specialized cattle farming in the Neolithic Rhine-Meuse Delta: Results from zooarchaeological and stable isotope (δ18O, δ13C, δ15N) analyses.

Schipluiden (3630–3380 cal BC), the earliest known year-round settlement in the Rhine-Meuse Delta in the Netherlands, is a key site for addressing the nature of Neolithic subsistence in the wetlands of northwestern Europe. A preliminary zooarchaeological study suggested that cattle husbandry was a major activity at Schipluiden. In contrast, stable carbon and nitrogen isotope analyses of human remains from the site indicated a marine-oriented diet, implying that the Mesolithic-Neolithic dietary transition continued well into the mid-4th Millennium BC in this region. Here, we re-investigate the role and nature of cattle husbandry at Neolithic Schipluiden using mortality profiles and stable isotope analysis (δ18O, δ13C, δ15N) of animal bone collagen and tooth enamel. The age-at-death analysis suggests that cattle were managed for both meat and milk production. The δ18O and δ13C analysis of tooth enamel provide evidence that calving spread over five-and-a-half-months, which would have led to a longer availability of milk throughout the year. Cattle were grazing in open, marshy environments near the site and winter foddering was practiced occasionally. The faunal isotopic data also reveal that the high 15N in human bone collagen is more likely to signal the consumption of products from cattle that grazed on 15N-enriched salt marsh plants around the site, rather than a marine-oriented diet. This undermines the previous interpretation of the dietary practices at Schipluiden by showing that human diet in mid-4th millennium BC Rhine-Meuse area was fully “Neolithic”, based primarily on products from domesticates, especially cattle, with some input from wild terrestrial and aquatic resources available in their surroundings, contrary to what has been proposed before. Collating these results demonstrates a high level of investment in cattle husbandry, highlighting the social and economic importance of cattle at the lower Rhine-Meuse Delta during the 4th millennium BC.

Van Bataafse auxiliarii naar Frankische foederati

Summary In the Late Roman period the Batavians disappeared from the written sources, and archaeologically speaking, nearly all rural settlements and cities of the Southern Netherlands ceased to exist, alongside the civilian centres. There is no good explanation for this depopulation but slight hints point to the population’s deportation. In the early 5th century several settlements were inhabited again. Judging by the style of the house plans, the pottery and jewelry, the inhabitants came from the area north of the Rhine. Ubiquitous gold finds in the same area imply that they were paid by the Roman government. They are called Franks in the written sources and most likely served as foederati when regular Roman troops left in 401/402. Migration has always been a thorny issue in archaeology: based on ethnic interpretation of artefacts, arrows were drawn on maps, but theoretical objections silenced this approach, at least in theoretically-oriented archaeology. Migration can further be researched by new scientific methods (aDNA and isotope analysis of human remains); the results for the Roman period are not yet spectacular. More is expected from the analysis of settlement complexes by various methods: a) provenancing pottery by geochemical and mineralogical analysis, b) combined with stylistic study; c) isotopic analysis of associated animal bones, to see whether the animals were brought on the hoof over long distances; d) stylistic analysis of the house plan, and e) plotting the circulation area of the metal jewelry. This combination can ascertain whether the inhabitants of settlements were migrants originally and how quick they adapted to their new environment.

Mobility and diet in Prehistoric Denmark: strontium isotope analysis and incremental stable isotope analysis of human remains from the Limfjord area

The Limfjord in Denmark held a prominent position throughout Prehistory as a natural communication port between east and west. Identifying the presence of non-local individuals might shed light on socio-economic and cultural changes occurring in the Limfjord area. Existing studies attempting to do so using strontium isotope analysis on Danish prehistoric remains focus on certain archaeological time periods and geographic locations, resulting in an uneven distribution of analysed material. This study aimed at filling a gap in the existing literature, both from a geographical as well as a chronological point of view. Additionally, carbon and nitrogen stable isotope analysis on bone and tooth dentine from these individuals was carried out to examine dietary changes between childhood and adulthood. The strontium isotope results revealed four non-local individuals, two from the Neolithic, one from the Early Roman Iron Age and one from the Germanic Iron/Viking Age. We conducted incremental stable isotope analysis of tooth dentine from the four non-local individuals to investigate the palaeodietary information in their dental records at a higher resolution and potentially pinpoint their age at the time of movement. The two Neolithic individuals revealed stable isotope ratios that might be indicative of stress.

Laser ablation strontium isotope analysis of human remains from Harlaa and Sofi, eastern Ethiopia, and the implications for Islamisation and mobility

ABSTRACT The ancient city of Harlaa in eastern Ethiopia was occupied between the mid-6th and early 15th centuries AD and played a significant role as a trading centre with links internationally. Besides goods, these trade links also served in spreading cultural and religious ideas between continents, including Islamic traditions which became prevalent in Ethiopia during this time. Here, we present the first strontium isotope analysis of human remains from an Islamic site in Ethiopia. Results show that individuals buried following Islamic traditions include people born and raised both in Harlaa itself and also in rural communities from the surrounding hinterland, revealing a resident local Muslim community and potential co-existence of Muslim and non-Muslim individuals across economic sectors. The repeatability of results produced by laser ablation in human teeth sampled multiple times around the tooth cusp is also confirmed, although small differences between simultaneously-forming molar elements from a single individual were observed.

Sr Isotope Analysis of Human Remains from Settlement Pits at Stillfried/March. Reappraising Diagenetic Changes

Objectives: Since the late 1970s, when the first human skeletal remains from a pit (V1141) located within the Late Bronze Age hillfort at Stillfried an der March, Austria, were discovered, their deviation from the predominant burial rite of cremation became the subject-matter of a variety of archaeological and bioanthropological studies. Through continuous archaeological excavations, further settlement pits with unusual human inhumation burials or depositions of isolated skeletal remains became apparent and posed the question of their possible non-local origin. The human samples in this study come from the Pits V841 and V1133, furthermore we re-investigate two individuals from V1141. The aim is to get a better understanding of Stillfried’s population structure and to enrich the debate about the mortuary practices of the Urnfield culture. Material and Methods: Here we present and discuss the radiogenic Sr isotope ratios determined in the enamel of eleven individuals from three settlement pits: eight individuals from Pit V841 and one individual, represented by a skull without mandible (calvarium) of a 12–13-year-old child from Pit V1133; two individuals were taken from Pit V1141 and re-investigated for comparative reasons. We compared all data to signals of the local environment derived from modern environmental samples and to the autochthonous signal of the Late Bronze Age derived from archaeological faunal remains (incl. mussels) and archaeological plants. Further, we investigated and discussed the potential of a mathematical approach to access biogenic Sr isotopic information from diagenetically altered dentine. Results: It has been shown that both supposedly autochthonous and allochthonous (non-local) individuals are buried within the settlement pits of Stillfried, which shows that burial practices do not relate to the individual’s origins. In particular, the n(87Sr)/n(86Sr) isotopic values of six individuals match the supposedly autochthonous Sr signature, while the other five individuals represent allochthonous individuals. Three of the latter showed n(87Sr)/n(86Sr) values that were higher and two that were lower compared to the autochthonous Sr range, thereby indicating at least two different homelands. Despite the small sample size which constrains the validity of the data, the diversity of the inhabitants’ provenance reflects a high mobility. This may support the interpretation of Stillfried as a ‘central site’ – a finding which is also important in the wider context of the European Late Bronze Age.

Diet, cuisine and consumption practices of the first farmers in the southeastern Baltic

With the arrival of the Early Neolithic Globular Amphora and Corded Ware cultures into the southeastern Baltic, ca. 2900/2800–2400 cal BC, a new type of economy was introduced, animal husbandry. However, the degree to which this transformed the subsistence economy is unknown. Here, we conducted organic residue analyses of 64 ceramic vessels to identify their contents. The vessels were sampled from 10 Lithuanian archaeological sites dating across the Subneolithic-Neolithic transition to the Early Bronze Age (ca. 2900/2800–1300 cal BC). Our results demonstrate that regardless of location or vessel type, many ceramics were used to process aquatic resources. Against our expectations, this association continued even after marked economic change concurrent with the migration of pastoralists from central and southeastern Europe, as evidenced by recent ancient DNA analysis of human remains. Moreover, we observed dairy fats in pottery from all cultures of the Early Neolithic (i.e. Rzucewo, Globular Amphora and Corded Ware) but unlike other regions of Europe, it seems that these were incorporated into indigenous culinary practices. Furthermore, some vessels were used to process plant foods, and others may have been used for the production and/or storage of birch bark tar. However, evidence for domesticated plant processing, for example millet, was absent. We show that organic residue analysis of pottery provides a different picture of past consumption patterns compared to the stable isotope analysis of human remains from isolated burials where a clear dietary shift is evident.

I’ve Got Experience! Dawnie Wolfe Steadman1 * In 2009, the National Academy of Sciences released a blistering report on the current state of forensic science oversight and practice in the United States. The report skewered the current scientifijic integrity and standards of a number of forensic subdisciplines, including fijingerprints , blood spatter, bite marks, and ballistics, and offfered specifijic recommendations to improve forensicscience.Anthropologywasnotspecifijically mentioned in the report, but the same criticisms leveled at the other disciplines, including poor training in quantitative methods, little attention to standards, and the abject lack of errors associated with methods, were obviously relevant to forensic anthropology. To the credit of the discipline, anthropologists have produced scores of articles that focus on quantitative analyses (e.g., Algee-Hewitt 2016, 2017; Hefner et al. 2014; Kooi and Fairgrieve 2013; Megyesi et al. 2005; Slice and Algee-Hewitt 2015; Stoyanova et al. 2015, 2017), validation studies (e.g., Jooste et al. 2016; Kenyhercz et al. 2017a, 2017b; Kim 2016; Milner and Boldsen 2012; Savall et al. 2016; Suckling et al. 2016), and cognitive bias in our methods (Nakhaeizadeh et al. 2014a, 2014b, 2018). The rise of “computational anthropology ,”theuseof advancedcomputingtoproduce models, simulations, and predictive modeling to address complex problems in anthropology, offfers unlimited opportunities for forensic anthropology . The technological explosion of quantitative computing and big-data analysis tools has formed an important space in anthropology, including demography, ethnography, and past and present migration studies, yet forensic anthropology has remained largely unchanged by these advancements . Despite the warnings of the National Academy of Sciences and recent computational effforts in the fijield, those who are most likely to practice forensic anthropology continue to rely on traditional techniques and personal experience rather than quantitative approaches. Here I explore some of the historical and structural reasons behind the slow acceptance of new methods based on large (and/or simulated) data sets and computational approaches highlighted in these special issues of Human Biology and offfer some guidance for moving forward. Forensic anthropology is the application of the principles of skeletal biology to medicolegal questions, such as the identifijication of unknown remainsandinterpretationof traumatothebones. Forensic anthropologists are called into the most challengingforensiccontextsinthattheyworkwith humanremainsthataredecomposed,fragmentary, burnt,cremated,incomplete,andotherwisevisibly unidentifijiable. Unlike other forensic fijields that focus on a single set of techniques and tasks (e.g., fijingerprints, DNA, ballistics), forensic anthropologists can be asked to complete four disparate tasks in a single case: search and recovery of human remains, personal identifijication, trauma analysis, and estimation of the postmortem interval. Other 000 ■ Steadman specialized tasks may include facial reproduction techniquestogarnerleadsfromthepublicconcerning the identity of unknown remains and isotope analysis of human remains to assess geographic origins and migration history that may also assist with identifijication. These distinct responsibilities preclude the ability to develop a single set of best practices and lead to a crowded playing fijield of methods. For example, the task of personal identifijication begins with assessing the biological profijile—estimationsof sex,ancestry,age,andstature from the skeleton, each of which may consist of multiple methods. While stature estimates rely on regression formulas derived from various sized reference samples, most of the other methods are historically based on qualitative observations of skeletal morphological traits. Comfort levels with methods developed in the 1980s and 1990s based exclusively on macroscopic morphological age-, sex- or populationbasedvariation (calledhere“traditionalmethods”) seem to preclude the inclusion of important new techniques that use large sample sizes (including simulated data and machine learning), quantitative data such as three-dimensional imaging techniques, and sophisticated statistical analyses. For instance, transition analysis is a maximumlikelihood approach developed for bioarchaeological samples using three skeletal indicators and choiceof priors,providinganoutputof amaximum likelihood estimate and 95% confijidence interval...

How Fishy was the Inland Mesolithic? New Data from Friesack, Brandenburg, Germany

ABSTRACTRecent studies have shown that faunal assemblages from Mesolithic sites in inland Northern Europe contain more fish remains than previously thought, but the archaeological and archaeozoological record does not reveal the dietary importance of aquatic species to hunter-gatherer-fishers, even at a societal level. For example, the function of bone points, as hunting weapons or fishing equipment, has long been debated. Moreover, traditional methods provide no indication of variable subsistence practices within a population. For these reasons, paleodietary studies using stable isotope analyses of human remains have become routine. We present radiocarbon (14C) and stable isotope data from nine prehistoric human bones from the Early Mesolithic-Early Neolithic site of Friesack 4, and isotopic data for local terrestrial mammals (elk, red deer, roe deer, wild boar, aurochs, beaver) and freshwater fish (European eel, European perch). The reference data allow individual paleodiets to be reconstructed. Using paleodiet estimates of fish consumption, and modern values for local freshwater reservoir effects, we also calibrate human 14C ages taking into account dietary reservoir effects. Although the number of individuals is small, it is possible to infer a decline in the dietary importance of fish from the Preboreal to the Boreal Mesolithic, and an increase in aquatic resource consumption in the Early Neolithic.

A palaeomobility study of the multi-period site of Sigatoka, Fiji, using strontium isotope analysis

One of the most important archaeological sites in Fiji is located in the Sigatoka Sand Dunes National Park, on the southwest coast of Viti Levu. Numerous excavation projects at Sigatoka since the 1960s have revealed multiple episodes of human occupation, including burials, and a well-defined cemetery complex. This paper uses strontium isotope analysis of human remains from Sigatoka to investigate the residential mobility for 53 individuals from the site. In order to establish the local baseline of bioavailable strontium around Sigatoka, we have collected and measured the strontium isotopic compositions of 59 modern environmental samples from 15 localities across the island. Results suggest that the bioavailable strontium of Viti Levu is derived from a combination of oceanic- (i.e. sea spray) and geological-strontium, and the relative contribution of each source varies from location to location. This variation allows us to identify individuals from Sigatoka as being from local or non-local contexts, providing additional insight into the Fijian past.

Re-approaching palaeodiet in the Andes: use and application of sulphur isotope analysis in reconstructing Peruvian palaeodiet

This research critically examines palaeodietary analyses in ancient Peru. Research is often approached using ceramics, flora, and faunal remains to examine human diet and behaviour prior to written records however these remains may not be indicative of items used exclusively for subsistence. More directed approaches employ stable isotope analyses of human remains as these data can provide direct indication of foods consumed during life. Peruvian isotope studies focus on 13C-enrichment patterns, and follow the premise that maize (corn) was the main source of 13C-enrichment recorded in bone collagen. Recent studies in Peru have identified other dietary sources that cause similar enrichment patterns, including kiwicha (pseudocereal), marine protein (e.g. shellfish, fish, and seals), and mococho (seaweed). As a result, additional methodologies must be employed to more sufficiently identify sources of subsistence in ancient Peru. I propose that stable sulphur isotope methodology may be used to overcome the issues presented. By critically reviewing previous palaeodietary analyses of Peru I examine current limitations and overview the application potential of carbon and nitrogen isotope studies complemented with sulphur isotope analysis of human and faunal remains within a Peruvian context. Ultimately I advocate for a more comprehensive approach to Peruvian palaeodiet.

A Second Mortuary Hiatus on Lake Baikal in Siberia and the Arrival of Small-Scale Pastoralism

The spread of pastoralism in Asia is poorly understood, including how such processes affected northern forager populations. Lake Baikal’s western shore has a rich Holocene archaeological record that tracks these processes. The Early Bronze Age here is evidenced by numerous forager burials. The Early Iron Age (EIA) is thought to mark the arrival of pastoralists, but archaeological remains from this period have received little analysis. New radiocarbon dates for EIA human remains from 23 cemeteries indicate that no burials were created along this shore for ~900 years. This period, from ~3670 to 2760 cal. BP, spans from the end of the Early Bronze Age to the advent of the EIA. The burial gap may mark disruption of local foraging populations through incursions by non-local pastoralists. Radiocarbon dates on faunal remains indicate that domestic herd animals first appear around 3275 cal. BP, just prior to the first EIA human burials. Stable carbon and nitrogen isotope analysis of human remains and zooarchaeological data indicate that domestic fauna were minor dietary components for EIA people. Like preceding foragers, the EIA groups relied extensively on Baikal’s aquatic food sources, indicating that the scale of pastoralism during this period was relatively limited.

Geochemical Analyses of Marmot Teeth to Evaluate the Potential for Overlapping Foraging Ranges in Two Siberian Human Cemetery Populations

Stable carbon and nitrogen isotope analyses of human remains from two contemporaneous cemeteries in the Lake Baikal region of Russia indicate similarity in diets among some individuals buried in these two locations. Given that the Middle Holocene cemeteries are only 75 km apart, these dietary data could indicate overlap in foraging ranges between the two human cemetery populations. Incisors from Siberian marmots (Marmota sibirica) are the most abundant type of faunal remains recovered from both cemeteries. Siberian marmots are a steppe species and hibernate over much of the year, being readily accessible to humans only during the summer and early fall. They are a fat-rich and desirable food item today in adjacent portions of Central Asia. To test if the dietary similarity between the two cemetery human groups might be due to overlapping hunting areas for marmots, Barium/Calcium and Strontium/Calcium ratios in a sample of marmot teeth were examined. The results of these analyses indicate very little overlap in the trace element values for the marmot teeth from the two cemeteries, which suggests the two human groups were procuring marmots in different regions. We argue that the dietary similarity seen between the two cemeteries can be best accounted for by shared use of isotopically similar fish moving between Lake Baikal and its tributary, the Angara River. An alternative explanation is that the overlapping isotope values are a result of human migration between the two cemetery regions.

Productivity of Premodern Agriculture in the Cucuteni-Trypillia Area.

We present paleoeconomy reconstructions for premodern agriculture, selecting, wherever required, features and parameter values specific for the Cucuteni-Trypillia cultural unity (CTU; 5,400-2,700 BC, mostly the territory of modern Ukraine, Moldova, and Romania). We verify the self-consistency and viability of the archaeological evidence related to all major elements of the agricultural production cycle within the constraints provided by environmental and technological considerations. The starting point of our analysis is the paleodiet structure suggested by archaeological data, stable isotope analyses of human remains, and palynology studies in the CTU area. We allow for the archeologically attested contributions of domesticated and wild animal products to the diet, develop plausible estimates of the yield of ancient cereal varieties cultivated with ancient techniques, and quantify the yield dependence on the time after initial planting and on rainfall (as a climate proxy). Our conclusions involve analysis of the labor costs of various seasonal parts of the agricultural cycle of both an individual and a family with a majority of members that do not engage in productive activities that require physical fitness, such as tillage. Finally, we put our results into the context of the exploitation territory and catchment analysis, to project various subsistence strategies into the exploitation territory of a farming settlement. The simplest economic complex based on cereals and domestic and wild animal products, with fallow cropping, appears to be capable of supporting an isolated, relatively small farming settlement of 50-300 people (2-10 ha in area) even without recourse to technological improvements such as the use of manure fertilizer. Our results strongly suggest that dairy products played a significant role in the dietary and labor balance. The smaller settlements are typical of the earliest Trypillia A stage but remain predominant at the later stages. A larger settlement of several hundred people could function in isolation, perhaps with a larger fraction of cereals in the diet, only with technological innovations, such as manure fertilizer and, most important, ard tillage. The ard radically relieves the extreme time pressure associated with soil preparation for sowing. It appears that very large settlements of a few hundred hectares in area, found in the CTU region, could function only if supported by satellite farming villages and stable exchange networks. In turn, this implies social division of labor and occupation, sufficiently complex social relations, stable exchange channels, and so on: altogether, a proto-urban character of such settlements. A model is proposed for the lifetime of a farming settlement, assuming that it is limited by the soil fertility (the depleted resources model), that provides a lifetime estimate consistent with the archaeological evidence available (100-150 years). The model shows that the lifetime strongly depends on the fraction of the arable land area kept fallow. We also discuss, quantify, and assess some strategies to mitigate the risks of arable agriculture associated with strong temporal fluctuations in the cereal yield, such as manure fertilization, and increased fraction of cereals in the diet combined with producing grain surplus for emergency storage.

Social stratigraphy in Late Iron Age Switzerland: stable carbon, nitrogen and sulphur isotope analysis of human remains from Münsingen

The Iron Age cemetery of Münsingen in Switzerland with 220 abundantly equipped burials marked a milestone for Iron Age research. The horizontal spread throughout the time of its occupancy laid the foundation for the chronology system of the Late Iron Age. Today, skulls of 77 individuals and some postcranial bones are still preserved. The aim of the study was to obtain information about diet, mobility and social stratification of the individuals. Stable isotope ratios of carbon, nitrogen and sulphur were analysed for 63 individuals. For all of them, C3 plants were found to be the staple food. There are significant differences between males and females in δ13C and δ15N values. This points to a gender restriction in the access to animal protein with males probably having more access to meat and dairy products. Differences in δ15N values were also observed for different age classes. δ34S values indicate a terrestrial-based diet with no significant intake of marine or freshwater fish. Seven adults with enriched δ34S values might have immigrated to Münsingen, four of which were found in the oldest part of the cemetery. Furthermore, possible changes of the vegetation are indicated by the more positive stable carbon ratios in the later phases. The results lead to the suggestion that especially males buried with weapons might have played a special role in the Iron Age society.

"Celtic migrations": fact or fiction? Strontium and oxygen isotope analysis of the Czech cemeteries of Radovesice and Kutná Hora in Bohemia.

Strontium and oxygen isotope analysis of human remains from the early La Tène (fourth/third century BC) Czech cemeteries of Radovesice I (RAD I), Radovesice II (RAD II), and Kutná Hora were conducted to investigate the importance of residential changes during the period of the historic "Celtic migrations". In the initial phases (LT A/B), the grave goods of these cemeteries are typical for the core area of the La Tène culture, while around 300 BC (LT B2) an alteration occurs and typical Bohemian styles arise, and connections to Moravia and the Danubian region become visible. The strontium isotope ratios are highly varied with (87) Sr/(86) Sr values between 0.7062 and 0.7153 in Radovesice, and between 0.7082 and 0.7147 in Kutná Hora. The oxygen isotope data are more homogeneous and yield δ(18) Op ratios from 14.8‰ to 17.2‰ [mean: 16.2‰ ± 0.5 (1σ)] in Radovesice, and from 14.9‰ to 17.3‰ [mean: 16.5‰ ± 0.6 (1σ)] in Kutná Hora. Because the geological properties of the landscapes around the sites are variable and complex, most of the observed variations among the strontium isotope ratios may have been caused by agricultural practices, such as regularly changing farming land. Nevertheless, there are some individuals who differ completely from the regional isotopic baseline values. This suggests that at least a small part of the community migrated, which does not seem to be correlated with any particular phase of the La Tène period. Remarkably, it is mainly males who seem to be of nonlocal origin, and particularly those who were buried as warriors. Females, on the other hand, appear to have been more closely bonded to the Bohemian region. Whether the "foreign" individuals with differing isotopic compositions came from Moravia or the Danubian region remains debatable.

Strontium isotopes of human remains from the San Martín de Dulantzi graveyard (Alegría-Dulantzi, Álava) and population mobility in the Early Middle Ages

Strontium isotope analysis of human remains from San Martín de Dulantzi (Alegría-Dulantzi, Álava, Spain) graveyard has been used to establish mobility patterns during the Early Middle Ages. Some archaeological human remains had Germanic grave goods. Through radiogenic strontium isotope analysis, local origin individuals and immigrants were differentiated. Archaeological human bone samples exhibit 87Sr/86Sr = 0.70779–0.70802 values similar to domestic fauna isotope composition, indicating local origin of individuals or long residence time in the region. Comparing these data with tooth enamel values, two groups of immigrants from distinctive geological environment were established. The Dulantzi population constituted mainly a local society with influxes of immigrants. The foreign individuals are distributed through the studied period of time, suggesting that migration movements were limited in number. Isotopic signatures indicating mainly local individuals, linked to grave goods with archaeological attribution to Germanic origin, question the previous ethnic paradigm.

Retention of hunter–gatherer economies among maritime foragers from Caleta Vitor, northern Chile, during the late Holocene: evidence from stable carbon and nitrogen isotopic analysis of skeletal remains

On the basis of stable carbon and nitrogen isotope analysis of human remains, this paper provides evidence for the retention of hunter–gatherer economies among coastal inhabitants in northern Chile during the late Holocene – at the same time that inland populations were adopting agricultural economies. Coastal diets from the Caleta Vitor region of the Atacama Desert were dominated by marine-based foods, predominantly from upper trophic levels. The focus on reliable marine food resources is interpreted as a risk minimisation strategy in this marginal arid environment. Although these coastal hunter–gatherers adopted other goods and traditions from agricultural populations, their participation in this larger interregional exchange network did not affect their basic subsistence economies.Associated new radiocarbon dates from the site are also discussed. Skeletal remains and artefacts associated with the Caleta Vitor shell middens generally originate from sites with dates ranging from c. 9000–476 BP. However, the human remains that are the subject of this research cover the time period c. 4000–476 BP.
