In addition, diets rich in marine resources have a major impact on biogenic strontium, averaging terrestrial values with the marine signal of 0.7092 (Lahtinen et al., 2021). Therefore, it is important to temper interpretation with dietary isotope proxies such as carbon (δ 13 C), nitrogen (δ 15 N) and sulphur (δ 34 S) ( Madgwick et al., 2019a ).
