Statistische und Naturwissenschaftliche Untersuchungen 173 strategies could be identified in the population at Kleinha- dersdorf369, we sampled teeth and bone from the skeletal collection and analysed them for strontium, carbon and ni- trogen isotopes. The protein composition of bone collagen reflects the last 10–20 years of an individual’s diet depending on the specific bone sampled and carbon and nitrogen iso- topes (expressed as δ13C and δ15N) reveal the proportions of proteins in the diet derived from plants and meat/dairy pro- ducts respectively370. The (87Sr/86Sr) strontium ratio in the tooth gives a geographic ‘signature’ arising from the locality where an individual sourced most of their drinking water and diet371. Tooth enamel is favoured for analysis as it is un- likely to have suffered diagenesis in the ground and we pre- dominantly sampled molars, which form in childhood (M1: 1–3 years; M2: 3–6 years; M3: early teens)372. As the analytical procedure is necessarily destructive, care was taken during sampling not to remove any diag- nostic bone or destroy features on the molars (such as cari- es). Of the approximately 45 individuals interred at Klein- hadersdorf, 39 were sampled for isotopic analysis. 36 of the bone samples returned results, including 16 adult males, 10 adult females and 11 juveniles, and 42 87Sr/86Sr ratios were produced on 15 adult males, 9 females and 10 juveniles. In a number of cases we sampled two molars from one individu- al to investigate whether we could detect changes in move- ment during childhood. M1 and M3 were sampled from the individuals in graves 5a, 57, 65 and 66 from the most recent excavations and G. 14, G. 15 and G. 18 from the excavations which took place in 1931. 6.4.2 Procedure Carbon and Nitrogen: Collagen was extracted from up to 1.2  g of bone per sample using a standard protocol373.

This cemetery site was sampled as part of the “First farmers in Central Europe: diversity in LBK lifeways” project, running jointly between Cardiff, Durham and Oxford universities and funded by the Arts and Humanities Research Council UK. This project ran for three years (2008–2011) and sampled 25 sites across six regions of the LBK (Alsace, Baden-Württemberg, Bavaria, Austria, Czech Repub- lic, Slovakia and Hungary). It was carried out in collaboration with numerous partners on the continent and final results were presented in the monograph Bickle, Whittle 2013. It is currently envisaged that a database of the results will be available online through ADS (Archaeology Data Service).

Alexander Bentley, Robert Hedges, Daniela Hofmann, Julie Hamilton, Fernando Laiginhas, Geoff Nowell, D. Graham Pearson, Alasdair Whittle) 6.4.1 Introduction Isotope analysis allows greater insight into the diet and mo- bility of past communities which, when combined with the archaeological and environmental evidence, can offer pow- erful new understandings of age-, sex- or status-based diffe- rences amongst prehistoric populations368.
