Figure 9. Dietary isotopes (d¹³C and d¹⁵N) and ⁸⁷Sr/⁸⁶Sr values for three leprous individuals.

Measurements for the dietary isotopes are in duplicate and on both femurs and ribs representing bones with slow (femur) and faster (rib) collagen turnover rates [54]. d¹³C and d¹⁵N values are consistent with the expected diet of a northern European terrestrial C3 diet, with perhaps a small marine component. Elevated d¹³C and d¹⁵N of the ribs over the femur samples for each individual suggests increased marine or freshwater resource consumption later in life. The Sr isotope analyses are on enamel (E) and also one on dentine (D) to represent the diagenetic Sr signal. Three faunal whole tooth Sr isotopic values (R1-R3) are included to estimate the ‘local’ Sr range as are published isotopic ranges for Southern England and the Winchester region. The three human enamel samples fall within the isotopic range for the Winchester region and are therefore consistent with a Southern England childhood origin for these individuals.
