Abstract

In order to better evaluate the role plant exploitation
played at a Neolithic site (Con Co Ngua, ceramic context
dated to 5000 years BP) in Vietnam, we measured the δ13C
in apatite from human teeth at this site as well as from a
nearby Metal Period site (Nui Nap), with a carbon date of
1670 years BP, where δ 13C and δ 15N from collagen were
also measured. Ba:Sr ratios at both sites were determined
in order to estimate the importance of marine versus
agricultural food sources. Results are consistent with
incipient plant exploitation at Con Co Ngua, while dietary
C3 plants that might have included rice played a smaller
role than at Nui Nap. Marine sources appear to be more
significant at the earlier site.
