Dietary reconstruction and reservoir correction of 14 C dates on bones from pagan and early Christian graves in Iceland
In this study, δ 13 C and δ 15 N of bone samples from 83 skeletons (79 humans, 2 horses, and 2 dogs) excavated from pagan and early Christian graves from 21 localities in Iceland are used to reconstruct diet of the early settlers in Iceland and possible differences in diet depending on the distance...
