To confirm the dating of this individual and better clarify the ages of the associated material culture, we undertook additional radiocarbon dating, including two separate dates directly on the individual himself.We also re-dated the hat and robe fragments reported earlier, obtaining dates that were younger than initially reported but similar to the new dates we obtained on associated artifacts and on the Kwädąy Dän Ts’ìnchį man himself.Access to society journal content varies across our titles.If you have access to a journal via a society or association membership, please browse to your society journal, select an article to view, and follow the instructions in this box.These freshwater reservoir offsets (FROs) have been noted on human and dog bone in several areas of the world.

The individual was found in association with a number of artifacts, including a plant fibre hat, a robe-style fur garment and various wooden items.

Differences from within each of four pairs of wood charcoal vs.

marine shell (Nunivak Island) produce a weighted mean of 459 ± 32 years.

Variations in these apparent reservoir effects presumably result largely from the interplay of differential ocean water upwelling and customary faunal feeding areas, although possible effects of other species characteristics cannot be ruled out.

Dating of marine samples from the Bering Sea should thus either proceed with the expectation that age determinations may not be accurate within several centuries, or be approached through experimental measurement of reservoir effect among restricted faunal species in limited areas.
