Paleodiet reconstruction of Bronze Age Siberians from the mortuary site of Khuzhir-Nuge XIV,Lake Baikal

Paleodiet reconstruction using stable isotopes of carbon and nitrogen was carried out on individuals from the Bronze Age cemetery, Khuzhir-Nuge XIV on the western shore of Lake Baikal, Russian Federation. The cemetery contained 79 graves with 89 individuals and was in use between approximately 2700 and 2000 cal. B.C. with the exception of one burial, dated to around 4000 B.C. Archaeological and ethnographic evidence indicates that hunting and fishing were the main subsistence activities while gathering was less important. δ¹³C from collagen and carbonate apatite was analysed, along with δ¹⁵N from collagen. Bone mineral preservation was evaluated using Fourier transform infrared spectroscopy. δ¹³C and δ¹⁵N of collagen are positively correlated and reflect varying reliance on terrestrial mammals, fish, and seals from Lake Baikal. Lake Baikal biota exhibit considerable variation in δ¹³C at the base of the food web thus; there is variation in human δ¹³C (−20.1‰ to −16.2‰) despite the fact that there are no C₄ plants in the region. δ¹⁵N results (range 10.3‰–16.5‰) indicate that fish, and possibly seals, made up some of the diet for everyone, but in varying amounts relative to terrestrial herbivores. δ¹³C from carbonate is not correlated with δ¹³C from collagen, a situation that has been found in remains from other coastal sites. A mixed diet from both terrestrial and freshwater ecosystems is the most likely explanation. Analysis of mortuary variables within the cemetery reveals three distinct clusters of graves with variations in burial treatment among the clusters. δ¹⁵N values are significantly different among these clusters, suggesting an association between diet and mortuary customs.     

Fishing ancient Lake Baikal,Siberia: inferences from the reconstruction of harvested perch (Perca fluviatilis) size

Fishing was the foundation for many of the world's foraging peoples and was undertaken using a variety of technologies. Reconstructing fishing technologies can be difficult because these tools were often made of perishable materials. Here we explore fishing technologies employed at the Ityrkhei site on Lake Baikal, Siberia. Specifically, we employ regression analyses to reconstruct the sizes of perch (Perca fluviatilis) captured through time at the site. Our analyses demonstrate that almost no juvenile perch were taken, suggesting some selectivity in harvest. We suggest this selectivity is most consistent with the use of relatively large gauge nets or traps. Such mass harvesting technologies may have been important elements of the subsistence economies of Lake Baikal's foraging peoples throughout much of the Holocene.     

Stable carbon and nitrogen isotope analysis on human remains from the Early Mesolithic site of La Vergne (Charente-Maritime,France)

We report here the results of stable carbon and nitrogen isotope analysis of human and faunal remains from La Vergne (Charente-Maritime, western France), a rare Early Mesolithic burial site (ca. 8500–8000 cal BC). The results for nine humans (average δ¹³C = −19.3‰; δ¹⁵N = 9.4‰) indicate a strongly terrestrial diet, dominated by animal protein, with the possibility of, at best, a slight contribution of marine-derived protein. Given lower sea-levels in the early Holocene, the site would have been some 60–80 km from the sea at the time of its use; nevertheless, contacts with the coast are shown by the presence of numerous marine shell beads in the graves. In the light of the stable isotope results, it is suggested here that such contacts most likely took the form of exchange with coastal communities whose remains now lie underwater.     

Evaluation of radiocarbon dates from the Middle Holocene hunter-gatherer cemetery Khuzhir-Nuge XIV,Lake Baikal,Siberia

A data set of 87 radiocarbon determinations obtained for the Bronze Age Khuzhir-Nuge XIV cemetery in the Cis-Baikal region of Siberia is analyzed from the perspective of data quality and within the local archaeological context. Bone preservation, expressed in terms of collagen yields, is a very important factor affecting both the accuracy and precision of ¹⁴C dates and, therefore, publication of this information should be adopted as a required standard. According to the calibrated high-collagen dates, after a single Serovo interment the cemetery was used continuously by Glazkovo peoples for up to 700 years (∼2700–2000 BC), and 70% of all burials were interred within a relatively short peak period between approximately 2500 and 2300 BC. The extensive radiocarbon data from KN XIV allow for the re-evaluation of existing models and perspectives on the place of the Glazkovo culture within the Cis-Baikal Neolithic and Bronze Age.     

Estimating weaning and early childhood diet from serial micro-samples of dentin collagen

Age of weaning is an important measure of parental investment, and in various human and non-human primate studies, has been correlated with a range of developmental factors such as stature, cognitive functions, obesity, ability to cope with stress, and rates of disease. Archaeological estimation of the weaning process is generally at the level of an entire burial population, creating some challenges in using such data to test anthropological theory. We describe a method that tracks the weaning process at the individual level, based on the measurement of stable nitrogen and carbon isotope ratios in serial sections of first molar dentin collagen. We apply this micro-sampling technique to a sample of individuals from CA-CCO-548, a well-studied and ancient site on the banks of Marsh Creek in Central California. Results show great variation between individuals in both the length of the weaning process, the age at which breastfeeding stopped, and the source of early complementary childhood foods.     

New Insights into Mesolithic Human Diet in the Mediterranean from Stable Isotope Analysis: The Sites of Campu Stefanu and Torre d'Aquila,Corsica

Mesolithic human remains are rare in the archaeological record of the French Mediterranean. Only the island of Corsica has so far produced relatively well‐preserved burials, and recent archaeological excavations have brought to light new Mesolithic human remains. The site of Campu Stefanu , located in Sollacaro in the southeast of the island, contained a collective burial of seven to eight individuals in a previously unobserved funerary context. A re‐evaluation of collections in regional museums yielded the remains from another Mesolithic individual from the site of Torre d 'Aquila , excavated at Pietracorbara, in the northern part of the island, at the beginning of the 1990s. These two discoveries presented the rare opportunity to obtain new radiocarbon dates and paleodietary insights from this crucial time period using stable isotope analysis (δ¹³C, δ¹⁵N) on collagen. From Campu Stefanu, one individual had sufficient collagen preserved for radiocarbon dating, revealing that it is the oldest Mesolithic human known on the island, dated to 10216–9920 cal. BP. At Torre d'Aquila, radiocarbon dates indicate that the individual belonged to a younger Mesolithic phase than Campu Stefanu, dated to 9903–9596 cal. BP. δ¹³C and δ¹⁵N isotope ratios are similar between the Campu Stefanu and Torre d'Aquila individuals and indicate a diet dominated by the consumption of terrestrial animal protein and a lack of marine resources. These findings are in contrast with the previous results from two other Mesolithic individuals from Corsica from the sites of Araguina Sennola and Monte Leone , for which about 25–30% of the consumed proteins came from a marine diet. The dietary variability recorded in Corsica is consistent with results obtained from Mesolithic human remains of Sicily and the Iberian Peninsula. We can hypothesise, that despite the nomadic lifestyle, the distance to the sea played a major role in Mesolithic food choices in Corsica. Copyright © 2016 John Wiley & Sons, Ltd.     

Provisioning Inka feasts at Tiwanaku, Bolivia: the geographic origins of camelids in the Pumapunku complex

While political integration can be achieved by many means, here we focus on the use of feasting and statecraft in the Inka Empire of the Andean Late Horizon (c. AD 1400-1532) in South America. In order to examine Inka political integration of the Lake Titicaca Basin of Bolivia, we examine paleomobility and paleodiet through radiogenic strontium and stable oxygen and carbon isotope data in archaeological camelid remains from the site of Tiwanaku. Mean radiogenic strontium isotope values from all archaeological camelid enamel and bone samples is ⁸⁷Sr/⁸⁶Sr = 0.70998 ± 0.00179 (1σ, n = 48), mean stable oxygen isotope values from a sub-set of archaeological camelid enamel and bone samples is δ¹⁸O_{carbonate (VPDB)} = −10.0‰ ± 2.6‰ (1σ, n = 18) and mean stable carbon isotope values from a sub-set of archaeological camelid enamel and bone samples is δ¹³C_{carbonate (VPDB)} = −9.0‰ ± 1.7‰ (1σ, n = 18). While many camelids consumed in these feasting events were likely local to the Lake Titicaca Basin, others came from a variety of different geologic zones, elucidating our understanding of Inka statecraft and the role of feasting in political integration in empires in the past.     

Stable Isotopic Analysis of Human Skeletons from the Sunhung Mural Tomb,Yeongju, Korea: Implication for Human Diet in the Three Kingdoms Period

This study reports the results of stable isotope analyses (carbon, nitrogen and sulphur) of human bone collagen from the Sunhung mural tomb from the Three Kingdoms Period of Korea (AD 300–668). The stable isotope data indicate that the main source of protein in the diet of the interred seven Sunhung individuals came from C₃‐based terrestrial resources, and there was an isotopic variation between individuals at this site. To investigate dietary patterns in the Three Kingdoms period, we compared our results with reported isotopic data from other southeastern Three Kingdoms sites (Imdang‐dong, Songhyeon‐dong and Yean‐ri). We found that the Sunhung individuals had similar isotope ratios to the people from these other sites. However, there was noticeable isotopic difference among individuals from each study site, although much of the dietary protein in each site was mainly from terrestrial sources. We propose that the most parsimonious explanation for this isotopic pattern is variation in social status during this time period. Copyright © 2012 John Wiley & Sons, Ltd.     

Hunter–gatherer foraging ranges, migrations, and travel in the middle Holocene Baikal region of Siberia: Insights from carbon and nitrogen stable isotope signatures

Foraging ranges, migrations, and travel among Middle Holocene hunter–gatherers in the Baikal region of Siberia are examined based on carbon and nitrogen stable isotope signatures obtained from 350 human and 203 faunal bone samples. The human materials represent Early Neolithic (8000–6800 cal BP), Late Neolithic (6000–5000 cal BP), and Early Bronze Age periods (∼5000–4000 cal BP) and come from the following four smaller areas of the broader region: the Angara and upper Lena valleys, Little Sea of Baikal’s northwest coast, and southwest Baikal. Forager diets from each area occupy their own distinct position within the stable isotope spectrum. This suggests that foraging ranges were not as large as expected given the distances involved and the lack of geographic obstacles between the micro-regions. All examined individuals followed a similar subsistence strategy: harvesting game and local fishes, and on Lake Baikal also the seal, and to a more limited extent, plant foods. Although well established in their home areas, exchange networks with the other micro-regions appear asymmetrical both in time and direction: more travel and contacts between some micro-regions and less between others. The Angara valley seems to be the only area with the possibility of a temporal change in the foraging strategy from more fishing during the Early Neolithic to more ungulate hunting during the Late Neolithic–Early Bronze Age. However, the shift in stable isotope values suggesting this change can be viewed also as evidence of climate change affecting primary productivity of the Baikal–Angara freshwater system.     

Isotopic Investigation of Animal Husbandry in the Welsh and English Periods at Dryslwyn Castle,Carmarthenshire, Wales

Dryslwyn Castle in southwest Wales was founded by a Welsh lord in the AD 1220s, captured by the English in 1287, and declined from c.1407 until it was abandoned c.1450. In contrast to historical evidence for changes in procurement of meat, previous zooarchaeological work has suggested that throughout these three periods, there was no change in the supply of animals. We have analysed the stable carbon and nitrogen isotope values of 20 cattle and 25 pigs from the Castle to further test this hypothesis. Our results show that there was no detectable change in the source of supply of cattle to the Castle when it passed from Welsh to English control, though differences in isotope ratios compared to cattle from York suggest that such changes might well be detectable. For pigs, there was an increase in carbon isotope ratios in the English period and a reversion to the previous values in the decline period, which is interpreted as reflecting a change in diet of the pigs from woodland to more open environments. Such a change is anticipated locally due to human population pressure in the English period, but could also reflect a change in the region of supply. This paper shows that there is potential for developing isotope analyses as part of the study of medieval husbandry. Copyright © 2011 John Wiley & Sons, Ltd.     

Inferences from the human skeletal material of the Early Iron Age cemetery at Agios Dimitrios,Fthiotis, Central Greece

The Geometric cemetery of Agios Dimitrios (850–740 B.C.) yielded a human osteological sample, with an MNI of 51 and equal numbers of males and females and adults and subadults. This site is of significant archaeological importance, as it provides information on human health status, diet, and activity patterns as well as mortuary behavior for a little studied time period. The results, including a) stable carbon and nitrogen isotopic data suggesting a C₃ low-protein plant diet, b) relatively high infant mortality, c) low stature estimates, d) significant prevalence of possible anemic conditions, and e) high dental infection and loss rates, all point to a rapidly increasing, stressed, and relatively malnourished population which did not exploit nearby marine resources, experienced suboptimal living conditions, and could not reach its biological potential. Furthermore, the study of this group provides evidence of equal burial treatment of all age and sex categories, no dietary differences in terms of sex and status, and no sex differentiation in pathological conditions.     

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.     

Prehistoric Seal Hunting on Lake Baikal: Methodology and Preliminary Results of the Analysis of Canine Sections

A number of archaeological sites on Lake Baikal revealed evidence of Neolithic and Bronze Age seal hunting. A collection of 35 canines from four sites was used to develop a methodology for analysing growth increments of canine dentine for the purpose of examining aspects of prehistoric seal hunting. Results from this preliminary analysis indicate that seal hunting at these sites was a seasonal activity confined to spring and early summer. Baikal seals were probably hunted in early spring for their meat, blubber and furs, and later in the season for their meat and skins.     

Stable isotopic evidence of diet in a Greek colonial population from the Black Sea

Archaeological and literary sources indicate that the ancient Greeks relied heavily on terrestrial resources and that their access to certain types of foods varied by sex and status. Human and faunal remains from the Greek colonial site of Apollonia (5th to 2nd century BC) on the Black Sea coast of Bulgaria were analyzed for stable carbon and nitrogen isotopes in order to reconstruct the diet of this population, investigate the relative importance of marine vs. terrestrial resources, and explore variations in diet with respect to age, sex, and burial type. The results of this study indicate that the colonists of Apollonia relied on a mixed diet of terrestrial and marine foods, and that there was little or no variation in diet by age, sex, or burial type. The relationship between δ¹³C and δ¹⁵N data for these samples suggests that while marine foods were an important source of nitrogen, much of the carbon used to construct amino acids came from terrestrial foods.     

The Upper Paleolithic of Northern Asia: Achievements,problems, and perspectives. III. Northeastern Siberia and the Russian Far East

Research into the Upper Paleolithic of northeastern Asia began in the 1940s. Recent work has led to the discovery of numbers of sites, some of them more than 30,000 years old, which are assigned to the D'uktai culture. The material recovered from these sites indicates relationships between the D'uktai culture and other cultures in Europe, Japan, Korea, China, and North America. For the most part, however, these similarities do not result from a spread of cultural traits from Europe into Asia. Instead, most of them reflect local development of the Upper Paleolithic, within both Asia and Europe, out of local Middle Paleolithic industries, which were themselves originally similar in technology and typology.     

Isotopic evidence of dietary variability in subadults at the Usu-moshiri site of the Epi-Jomon culture,Japan

This study reconstructs adult and subadult diets of a hunter-gatherer population of the Epi-Jomon culture (approximately 2300–1700 years BP) in Japan, using the stable isotopic analysis of carbon and nitrogen. The results suggest that the Usu-moshiri adults were highly dependent on marine resources such as seals for their dietary protein intake and that no significant dietary differences existed between the sexes. Among subadults we found two types of diet on the basis of different isotopic signatures. One group consisted of individuals with δ¹³C values below than those of the adult female mean minus two standard deviations and δ¹⁵N values lower than those of subadults in the other groups. These low-δ¹³C subadults indicated relatively less enriched δ¹⁵N values by 3.5 years of age at the latest. They probably consumed more ¹³C-depleted foods during weaning than in the ordinary adult diet. In the other high-δ¹³C group, their enriched δ¹⁵N values start to decline by four years of age and fall within the two-standard-deviations range of the total adult mean around five to six years of age. Isotopic values of children in this high-δ¹³C group suggest that they would have been fed ordinary adult diets during weaning. Perinates could also be divided into two groups on the basis of the similar patterns in their carbon and nitrogen isotope ratios. Our results indicate variabilities in the diets of subadults, and similar variabilities were also seen in ethnographic studies of the Ainu populations.     

Taxonomic, anatomical, and spatio-temporal variations in the stable carbon and nitrogen isotopic compositions of plants from an African savanna

Stable carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope ratios are commonly used to reconstruct palaeodiets and palaeoenvironments. The method is based on our knowledge of isotopic patterns in plants, which are subject to taxonomic and environmental variability. While previous researchers have addressed isotopic variability amongst plants, no studies have looked extensively at a broad suite of taxa over multiple temporal scales from within the savanna biome so as to provide baseline data for palaeodietary and palaeoenvironmental studies. Here we document variations in the isotopic compositions of plants collected over two years from the Kruger National Park, South Africa, with respect to species and anatomical differences, and the influences of geological substrate and spatio-temporal shifts in climate. Results show that environmentally-induced carbon isotopic variations in plants within this region are generally smaller than 2‰, which is lower than what has been previously reported for plants compared across multiple habitat-types. These data suggest that δ¹³C differences of 2‰ or more (or 1‰ if the diet is predominantly C₄) between animals from a given area reliably indicate real dietary differences. Plant δ¹⁵N values vary greatly between different microhabitats (by up to 4‰), responding to a range of environmental influences that may, in turn, significantly influence variation in animal δ¹⁵N values.     

Assessing the life history of an andean traveller through biogeochemistry: Stable and radiogenic isotope analyses of archaeological human remains from Northern Chile

Bioarchaeology and biogeochemistry can elucidate aspects of individual life histories that are often lost in the archaeological record. Here, we use stable and radiogenic isotope analyses of enamel, bone and hair to reconstruct paleodiet and paleomobility in an adult male interred along a pre‐Columbian route connecting the northern Chilean coast to the inland Loa River Valley. Although this well‐preserved burial included mortuary goods typical of coastal cultures, it was discovered in a vast, uninhabited part of northern Chile's hyper‐arid Atacama Desert. Variation in carbon and nitrogen isotopes reflects dietary differences, while strontium and oxygen isotopes vary geologically and geographically. We use these data to examine paleodiet and paleomobility and to assess whether this was a coastal traveller seeking provisions from the interior or vice versa. Enamel stable isotope analysis is consistent with the consumption of a mixture of terrestrial and marine resources during the first years of life. Bone stable isotope analyses indicate habitual consumption of marine foodstuffs over the last 10–30 years of this individual's life. Interestingly, stable isotope analysis of hair samples provides more fine‐grained information on this individual, suggesting movements between the coast and highlands in the months before his death. Radiogenic strontium isotope data are consistent with residence on the coast or in the Atacama Desert, but are lower than strontium isotope values from higher altitudes. These dietary and geological patterns are reconcilable with coastal residency; the isotopic data are consistent with foodstuffs and textiles found with the burial. Therefore, we argue that this individual was regularly moving from the coast to inland areas, crossing the hyper‐arid Atacama Desert by following strategic interzonal routes that provided access to particular resources.

Middle Holocene hunter-gatherers of Cis-Baikal, Siberia: An overview for the new century

The paper examines Middle Holocene hunter-gatherer adaptive strategies in the Baikal region of Siberia based on diverse data (radiocarbon, mortuary, geochemical, genetic, human osteological, and zooarchaeological) accumulated over the last 10–15 years. The new model emphasizes the cyclical nature of the long-term changes and recognizes similarities between the Early Neolithic and Late Neolithic–Early Bronze Age cultures. The overall impression seems to be that change in the region was rapid rather than gradual. A number of interesting correlations between various cultural and environmental variables have been identified. During the Early Neolithic and Late Neolithic–Bronze Age, the spatial distributions of mortuary sites, open landscape, and good fisheries are all correlated and both intervals are coeval with periods of environmental stability. For the Early Neolithic two additional sets of correlated variables have been identified: (1) the uneven distribution of fish resources, uneven distribution of the human population, and cultural heterogeneity; and (2) poorer overall community health, more extensive male travel and heavier workloads, and higher reliance on fishing. For the Late Neolithic–Early Bronze Age, the sets of correlated variables are somewhat different: (1) more even distribution of terrestrial game resources (herbivores), more even distribution of the human population, and cultural homogeneity; and (2) better overall community health, less travel and lighter workloads, more equitable distribution of labor between males and females, and higher reliance on game hunting. Viewed together, these patterns emphasize the much more dynamic pattern of hunter-gatherer cultural variability, temporally and spatially, compared to what was known before.
