Change of diet of the Greenland Vikings determined from stable carbon isotope analysis and (super 14) C dating of their bones.
Bone samples from the Greenland Viking colony provide us with a unique opportunity to test and use (super 14) C dating of remains of humans who depended upon food of mixed marine and terrestrial origin. We investigated the skeletons of 27 Greenland Norse people excavated from churchyard burials from...

Bone samples from the Greenland Viking colony provide us with a unique opportunity to test and use (super 14) C dating of remains of humans who depended upon food of mixed marine and terrestrial origin. We investigated the skeletons of 27 Greenland Norse people excavated from churchyard burials from the late 10th to the middle 15th century. The stable carbon isotopic composition (delta (super 13) C) of the bone collagen reveals that the diet of the Greenland Norse changed dramatically from predominantly terrestrial food at the time of Eric the Red around AD 1000 to predominantly marine food toward the end of the settlement period around AD 1450. We find that it is possible to (super 14) C-date these bones of mixed marine and terrestrial origin precisely when proper correction for the marine reservoir effect (the (super 14) C age difference between terrestrial and marine organisms) is taken into account. From the dietary information obtained via the delta (super 13) C values of the bones we have calculated individual reservoir age corrections for the measured (super 14) C ages of each skeleton. The reservoir age corrections were calibrated by comparing the (super 14) C dates of 3 highly marine skeletons with the (super 14) C dates of their terrestrial grave clothes.
