“…In fact, once growth is complete, the bone is continuously remodelled through a cycle of resorption and apposition. The rate of bone remodelling is estimated to be from 3 to 8% per year, and this rate decreases with advanced age, with differences between skeletal parts [81][82][83]. We also sampled a few milligrams of bone from the pars petrosa of one of the two foetuses (burial n. 241b), which were forming in utero in the last days of the woman's life…”

“…Sr isotope ratios were measured using a Neptune (ThermoFisher) multi-collector inductively-coupled-plasma mass spectrometer (MC-ICPMS) housed at the Centro Interdipartimentale Grandi Strumenti (University of Modena and Reggio Emilia). Seven Faraday detectors were used to collect signals of the following masses: 82 Kr, 83 Kr, 84 Sr, 85 Rb, 86 Sr, 87 Sr, 88 Sr. Sr solutions were diluted to~30 ppb and introduced into the Neptune through an APEX desolvating system. Corrections for Kr and Rb interferences follow previous works [e.g.…”

Human mobility in a Bronze Age Vatya ‘urnfield’ and the life history of a high-status woman

In this study, we present osteological and strontium isotope data of 29 individuals (26 cremations and 3 inhumations) from Szigetszentmiklós-Ürgehegy, one of the largest Middle Bronze Age cemeteries in Hungary. The site is located in the northern part of the Csepel Island (a few kilometres south of Budapest) and was in use between c. 2150 and 1500 BC, a period that saw the rise, the apogee, and, ultimately, the collapse of the Vatya culture in the plains of Central Hungary. The main aim of our study was to identify variation in mobility patterns among individuals of different sex/age/social status and among individuals treated with different burial rites using strontium isotope analysis. Changes in funerary rituals in Hungary have traditionally been associated with the crises of the tell cultures and the introgression of newcomers from the area of the Tumulus Culture in Central Europe around 1500 BC. Our results show only slight discrepancies between inhumations and cremations, as well as differences between adult males and females. The case of the richly furnished grave n. 241 is of particular interest. The urn contains the cremated bones of an adult woman and two 7 to 8-month-old foetuses, as well as remarkably prestigious goods. Using 87Sr/86Sr analysis of different dental and skeletal remains, which form in different life stages, we were able to reconstruct the potential movements of this high-status woman over almost her entire lifetime, from birth to her final days. Our study confirms the informative potential of strontium isotopes analyses performed on different cremated tissues. From a more general, historical perspective, our results reinforce the idea that exogamic practices were common in Bronze Age Central Europe and that kinship ties among high-rank individuals were probably functional in establishing or strengthening interconnections, alliances, and economic partnerships.

“…Bones are continuously remodelled thanks to regularly appearing ossification centres, and the tempo of the changes is determined not only by the metabolic level of the individual, but also by the type and structure of the bone (compact or spongy substance) in which they occur. Information on the isotope composition of the bone dates back to a period of 10 to 20 years before the death of the individual, and the remodelling process takes longer in adults than in children (Schweissing and Grupe 2000;Hodell et al 2004;Haverkort et al 2008;Stepańczak et al 2014).…”

“…All of the above factors should be taken into account when selecting animals as reference material for studying migration. However, such parameters as animal size and its metabolic rate are not as important in analysing strontium isotope levels as in the case of studying oxygen isotopes (Budd et al 2004;White et al 2004b;Stepańczak et al 2014).…”

Isotope analyses of bones and teeth allow us to study phenomena which occurred in the history of human species and which are difficult to capture by traditional anthropological methods. Measuring oxygen, nitrogen and carbon isotope levels in the skeleton makes it possible to reconstruct climatic changes, diet and/or the weaning process. Among isotopes used in such analyses are strontium isotopes, helpful in analysing migration and studying the mobility of historical and prehistoric human populations. In this respect, the proportion of two isotopes, the heavier87Sr and the lighter86Sr, is measured, following their extraction from the bioapatite of the bone mineral. Released from rocks in the weathering process, strontium permeates individual components of inanimate and animate environments, and then finds its way, together with food, to the human body. Thanks to comprehensive environmental studies and the measurement of the strontium ratio87Sr/86Sr in various animal tissues it is possible to determine the local isotope background for the environment. Values obtained by analysing human skeletons referenced against the range of environmental isotope variability enable researchers to trace back the location inhabited by the individual or group.

“…Thus, oxygen and strontium isotopes can map the isotopic outline of the area where an individual consumed the water and food during early childhood life (Bastos et al 2016). In addition to the prevailing environmental and geological conditions, the physiological and metabolic factors of an individual also play important role in deposition of oxygen isotopes (δ 18 O) in the bone tissues, so the origin and migration history of an individual should be carefully interpreted from oxygen isotope ratios estimated from bones of the deceased (Lisowska-Gaczorek et al, 2016) The δ 18 O ratios in bone tissues were found to increase after 40 years of age in females only, so sex and age of the bone should be estimated firstly before oxygen isotope estimates for interpretations of past human populations (Stepriczak et al 2014). …”

Role of stable isotope analyses in reconstructing past life-histories and the provenancing human skeletal remains: a review

This article reviews the present scenario of use of stable isotopes (mainly δ13C, δ 15 N, δ 18 O, 87 Sr) to trace past life behaviours like breast feeding and weaning practices, the geographic origin, migration history, paleodiet and subsistence patterns of past populations from the chemical signatures of isotopes imprinted in human skeletal remains. This approach is based on the state that food-web isotopic signatures are seen in the human bones and teeth and such signatures can change parallely with a variety of biogeochemical processes. By measuring δ 13 C and δ 15N isotopic values of subadult tissues of different ages, the level of breast milk ingestion at particular ages and the components of the complementary foods can be assessed. Strontium and oxygen isotopic analyses have been used for determining the geographic origins and reconstructing the way of life of past populations as these isotopes can map the isotopic outline of the area from where the person acquired water and food during initial lifetime. The isotopic values of strontium and oxygen values are considered specific to geographical areas and serve as reliable chemical signatures of migration history of past human populations (local or non-local to the site). Previous isotopic studies show that the subsistence patterns of the past human populations underwent extensive changes from nomadic to complete agricultural dependence strategies. The carbon and nitrogen isotopic values of local fauna of any archaeological site can be used to elucidate the prominence of freshwater resources in the diet of the past human populations found near the site. More extensive research covering isotopic descriptions of various prehistoric, historic and modern populations is needed to explore the role of stable isotope analysis for provenancing human skeletal remains and assessing human migration patterns/routes, geographic origins, paleodiet and subsistence practices of past populations.
