Stable isotopes as indicators of change in the food procurement and food preference of Viking Age and Early Christian populations on Gotland (Sweden)

Archaeological samples of human and faunal remains dating from the Viking (9–11th century AD) and Early Christian (11–12th century AD) periods of Gotland, Sweden were assayed through stable carbon and nitrogen isotope analysis in order to investigate whether changes in subsistence occurred between these periods, particularly regarding the importance of seafood. The study was concerned with how the dietary regime of the Baltic trading port and farming settlement at Ridana¨s, Gotland was affected by the widespread environmental and sociocultural transformations that characterized the end of the Viking Age. More generally, the research considers how changes in both food procurement and preference may account for observed differences in the dietary regimes of individuals from the Viking Age and the Early Christian period.

New perspectives in forensic anthropology


A critical review of the conceptual and practical evolution of forensic anthropology during the last two decades serves to identify two key external factors and four tightly inter-related internal methodological advances that have significantly affected the discipline. These key developments have not only altered the current practice of forensic anthropology, but also its goals, objectives, scope, and definition. The development of DNA analysis techniques served to undermine the classic role of forensic anthropology as a
field almost exclusively focused on victim identification. The introduction of the Daubert criteria in the courtroom presentation of scientific testimony accompanied the development of new human comparative samples and tools for data analysis and sharing, resulting in a vastly enhanced role for quantitative methods in human skeletal analysis. Additionally, new questions asked of forensic anthropologists, beyond identity, required sound scientific bases and expanded the scope of the field. This environment favored the incipient development of the interrelated fields of forensic taphonomy, forensic archaeology, and forensic trauma analysis, fields concerned with the reconstruction of events surrounding death. Far from representing the mere addition of new methodological techniques, these disciplines (especially, forensic taphonomy) provide forensic anthropology with a new conceptual framework, which is broader, deeper, and more solidly entrenched in the natural sciences. It is argued that this new framework represents a true paradigm shift, as it modifies not only the way in which classic forensic anthropological questions are answered, but also the goals and tasks of forensic anthropologists, and their perception of what can be considered a legitimate question or problem to be answered within the field.

Bone strontium: calcium ratios and duration of breastfeeding in a Mediaeval skeletal population


This work is an investigation of the value of bone strontium:calcium ratios in the study of duration of breastfeeding in earlier human populations. The study material comprised human skeletal remains of Mediaeval date from England. Investigation of diagenesis suggested that bone Sr:Ca ratios preserved a biogenic signal. Statistical analysis indicated significant age-related patterning in bone Sr:Ca ratios in the juvenile cohort. Duration of breastfeeding estimated from infant bone Sr:Ca ratios was concordant with that inferred from an earlier study of nitrogen stable isotope ratios from the same population. The value of bone Sr:Ca data for studying weaning practices in earlier human populations is discussed.

Amazing X-ray GIFs Show Joints In Motion


The human body has four types of movable joints. Most people don’t really think about them unless they start to become painful. In fact, their motion is really quite beautiful, but that beauty can be hard to appreciate because we usually can’t see how the bones are sliding around relative to one another.

14C dating and diet: a key to understanding the mobility of coastal populations of the Arabian Peninsula during the Neolithic

ABSTRACT Despite an often marginal position in prehistoric studies, the coasts have been a place of attraction for human settlements. In the Oman Peninsula, mainly along the coast of the Gulf of Oman and the Arabian Sea, the presence of highly productive marine environments, combined with relatively limited land resources, have led to intense exploitation of marine resources as evidenced by the large number of coastal sites since the sixth millennium BC. The issue of mobility of human groups has been raised repeatedly by researchers working in the area. Our study addresses this issue by an original geochemical approach, involving the radiocarbon dating method. This article presents the background, method, and first results.

Stable isotope variation in pathological bone

ABSTRACT Bone samples taken at autopsy from seven individuals from western Canada are studied histologically and the bone protein is analysed for stable isotopes of carbon and nitrogen. The objective of the study is to determine if pathological conditions result in variations in bone protein stable isotope ratios. Of the seven individuals sampled, three are normal and four are pathological. The latter include post-paralytic atrophy, healing fracture, active periostitis and healing osteomyelitis. The normal samples are included in order to determine how much variation to expect in different segments of a bone. In the three samples analysed, the variation is 90.3 for d13C and 90.2 for d15N. Three of the four pathological specimens exceed normal variation. The greatest variation occurs in the bone with osteomyelitis from an individual who had AIDS (the diseased segment was approximately 2‰ greater for d15N than the two normal segments from the same individual). The higher nitrogen isotope ratio in the bone segment with osteomyelitis is most likely a result of the fact that the collagen was formed from the catabolism of existing proteins in the body. This finding has implications for the interpretation of nitrogen isotope ratios in individuals who may have died from wasting diseases.

Lead isotope ratios: tracking the migration of European-Americans to Grafton, Illinois in the 19th century


ABSTRACT Lead isotope analysis was conducted using inductively coupled plasma mass spectrometer (ICP-MS) instruments on local soil samples and human premolar tooth enamel from a 19th century population from Grafton, Illinois, USA. The goal of the study was to determine if lead isotope analysis could be used to infer place of birth and patterns of 19th century migration into the city of Grafton. Five soil core samples from a location near Grafton, Illinois, five grave soil samples from the city cemetery and the tooth enamel of 19 human premolars were analysed. The results of the soil core analysis indicated that the lead isotopic signature of Grafton differs significantly from isotope ratios of other geographic areas associated with recorded places of birth of 19th century Jersey County residents. Elemental and isotope analysis of the soil samples indicated that diagenesis was not a factor in the analysis of lead isotopic signatures of enamel. From the lead isotope analysis of human premolars, the geographic origin of 13 of the remaining 15 individuals could be inferred. The inferred geographic origin was supplemented by an analysis of 1860 mortality and census records and demonstrated the utility of using lead isotope analysis in bio-archaeological investigations.

Sulphur isotopes in palaeodietary studies: a review and results from a controlled feeding experiment


ABSTRACT Recent advances in mass spectrometry now allow relatively routine measurements of sulphur isotopes (δ34S) in small samples (>10 mg) of tissue from archaeological human, plant, and faunal samples. δ34S values of human and faunal bone collagen can indicate residence or migration and can provide palaeodietary information. Here we present a review of applications of sulphur
isotopes to archaeological materials, and we also present preliminary results from one of the few controlled feeding experiments undertaken for sulphur isotopes. This study indicates that there is relatively little fractionation (−1‰) between diet and body protein (keratin) δ34S values for modern horses on a protein adequate C3 plant diet. In contrast, horses fed a possible low protein C4 feed have a diet to hair fractionation of +4‰ that could be the result of the input of endogenous sulphur from the recycling of body proteins.
