Abstract The isotope composition of tooth enamel and associated dentine and lead concentration was analyzed for strontium and oxygen (enamel) and carbon and nitrogen (dentine) from ten skulls taken from a burial pit found on the Chalk at Ridgeway Hill north of Weymouth, Dorset, on the south coast of England. These individuals are a subset of the 51 men in this pit, all of whom had been decapitated. The results from the ten individuals show that they were a diverse group of individuals. ATMS radiocarbon dating of three individuals gave dates that are statistically consistent and their weighted mean, when calibrated, provides a date range of AD 970–1025 (93% probability). The oxygen isotope composition ranges between 13.7‰ SMOW and 16.5‰SMOW, which result in drinking-water values between -15.4‰ SMOW and -9.2‰ VSMOW using the adapted Levinson calculation. They were raised in a climate that is colder than that of Britain, and one man has a signature that is consistent with an Arctic origin. The 87Sr/86Sr isot...
