Publication Microscopic Sampling of Dentine and Bone Collagen: Development of Sampling Methods for Carbon and Nitrogen Isotope Analysis(2021)Sampling methods for dentine and bone collagen have been evolving for several decades. Incremental dentine collagen sampling and bone collagen sampling have been limited by the available technology throughout that time. As the technology for isotope ratio mass spectrometry analysis improves, the sampling methods should improve as well. This research focused on developing a new incremental dentine collagen sampling method and bone collagen microsampling method for stable isotope analysis. This research aimed to increase the temporal resolution of incremental dentine collagen sampling and provided sequential collagen sampling from bone collagen for stable carbon and nitrogen isotope analysis while limiting the destructive nature of bioarchaeological analysis. It was determined that the temporal resolution for incremental analysis could be reduced to approximate three months, opposed to the nine months found in other sampling methods. It was also determined that detailed isotopic data could be obtained from bone collagen when sampling the microstructures. The increased amount of isotopic data from the bone collagen was an improvement on the commonly used bulk collagen sampling. This research can be utilised to answer several of the questions that archaeologists have been asking about past populations. Isotopic analysis using the methods developed in the research can provide a more detailed observation of the diet and health of past populations. In addition, the developed methods for bone and dentine collagen reduced the amount of tissue subjected to destructive analysis.Publication Kinship practices in Early Iron Age southeast Europe: genetic and isotopic analysis of burials from the Dolge njive barrow cemetery, Dolenjska, Slovenia(2023-04)DNA analysis demonstrates that all seven individuals buried in an Early Iron Age barrow at Dolge njive, southeast Slovenia, are close biological relatives. Although group composition does not suggest strict adherence to a patrilineal or matrilineal kinship system, the funerary tradition appears highly gendered, with family links through both the male and female line being important in structuring communities. We explore the implications for our understandings of kinship and funerary practices in Early Iron Age southeast Europe.Publication More than bones. An investigation of life, death and diet in later prehistoric Slovenia and Croatia(2017)The East Alpine region formed an important crossroads in later prehistoric Europe, through which ideas, people and objects flowed. This was particularly the case during the Late Bronze Age/ Early Iron Age, when an increasingly competitive society was evolving, with the formation of more complex social structures and the rise of ‘elites’. This has been evidenced in a shift in burial customs, from Urnfield-type cremation burial to the construction of tumuli and the adoption of elaborate inhumation burial. This multidisciplinary, multi-scalar approach to the analysis of human remains aims to explore the evolving structure, homogeneity and heterogeneity of communities inhabiting central and eastern Slovenia, and north-eastern Croatia, during the Late Bronze Age and Early Iron Age. The application of multiple methods, including the osteological analysis of cremated and non-cremated human remains, radiocarbon dating, stable isotope analysis (carbon, nitrogen, oxygen and strontium) and aDNA analysis has facilitated the exploration and interpretation of later prehistoric social structure and lifestyle. The use of carbon (from enamel carbonate and collagen) and nitrogen stable isotope analysis has highlighted important dietary distinctions between communities inhabiting this region and previous studies from elsewhere in contemporary Europe – specifically a high dependence on millet as a staple crop. This has been evidenced by δ13C values of between -17‰ and -15.3‰ from bone collagen. δ15N values of between 7.6‰ and 9.1‰ support this interpretation as they do not indicate the consumption of marine protein. Increased δ15N values of up to 13.5‰ from deciduous dentine have been interpreted as the influence of dietary and metabolic conditions, particularly in the presentation of an Infant exhibited palaeopathological evidence of severe metabolic disease. Complementary isotopic methods, including oxygen isotope ratios and enamel carbonate carbon, have also highlighted heterogeneity in childhood diet, reflecting the transition from a high lipid diet of breastmilk, to a diet of carbohydrates, indicative of weaning. In addition to these findings, the application of radiocarbon dating on cremated and nio-cremated human bone has expanded the current understanding of mortuary practices in this study area. Inhumation burial, previously thought synomemous with the Iron Age, has been now been identified throughout the Bronze Age at the cemetery of Obrežje. The application of this multi-scalar approach to combining and interpreting these data sets has allowed for the investigation of individual biographies, as well as regional trends. This research illustrates the advantages of bringing together multiple lines of evidence for the creation of informed interpretations regarding the life, death and diet of prehistoric peoples of the East Alpine region, and beyond.Publication 'Palaeoshellomics' reveals the use of freshwater mother-of-pearl in prehistory(2019-05)The extensive use of mollusc shell as a versatile raw material is testament to its importance in prehistoric times. The consistent choice of certain species for different purposes, including the making of ornaments, is a direct representation of how humans viewed and exploited their environment. The necessary taxonomic information, however, is often impossible to obtain from objects that are small, heavily worked or degraded. Here we propose a novel biogeochemical approach to track the biological origin of prehistoric mollusc shell. We conducted an in-depth study of archaeological ornaments using microstructural, geochemical and biomolecular analyses, including ‘palaeoshellomics’, the first application of palaeoproteomics to mollusc shells (and indeed to any invertebrate calcified tissue). We reveal the consistent use of locally-sourced freshwater mother-of-pearl for the standardized manufacture of ‘double-buttons’. This craft is found throughout Europe between 4200–3800 BCE, highlighting the ornament-makers’ profound knowledge of the biogeosphere and the existence of cross-cultural traditions.
