Abstract

Stable oxygen isotopes of bone structural carbonate (δ
18
O
carbonate
) and phosphate (δ
18
O
phosphate
) are frequently used for paleoclimatological and paleoenvironmental studies. In several studies, the more conveniently measureable δ
18
O
carbonate
values are measured, and δ
18
O
phosphate
values are approximated according to published regressions. We studied a variety of individuals (n = 101) of different wild and domesticated mammal species (n = 19) from the Viking Haithabu and medieval Schleswig sites in Northern Germany and demonstrated that a generalized relationship between δ
18
O
carbonate
and δ
18
O
phosphate
with a fixed value for oxygen isotope spacing (Δδ
18
O) is potentially error-prone. The Δδ
18
O values of our data set differ considerably from the commonly applied, fixed value of about 9 ‰ with values ranging from 3.8 to 8.1 ‰ (μ = 6.1 ‰ ± 0.9 ‰). Statistically significant differences in the Δδ
18
O values and marked differences in linear models established for the relationship between δ
18
O
carbonate
and δ
18
O
phosphate
are related to species-specific diet and physiology. Therefore, such species-specific particularities must not be neglected. We conclude that this variability does no longer permit an approximation of oxygen isotope values of bone phosphate from carbonate, because δ
18
O
phosphate
values approximated in such a way are highly error-prone. Parallel analyses of both δ
18
O
carbonate
and δ
18
O
phosphate
values are therefore indispensable.
