USE OF THREE ISOTOPES TO CALIBRATE HUMAN BONE RADIOCARBON DETERMINATIONS FROM KAINAPIRINA (SAC), WATOM ISLAND, PAPUA NEW GUINEA
Abstract
In archaeological dating, the greatest confidence is usually placed upon radiocarbon results of material that can
be directly related to a defined archaeological event. Human bone should fulfill this requirement, but bone dates obtained
from Pacific sites are often perceived as problematic due to the incorporation of 14C from a range of different reservoirs into
the collagen via diet. In this paper, we present new human bone gelatin results for 2 burials from the SAC archaeological site
on Watom Island, Papua New Guinea, and investigate the success of calibrating these determinations using dietary corrections
obtained from d34S, d15N, and d13C isotopes.
