Radiocarbon dates for archaeological chicken bones from South Island, New Zealand. Wk, Waikato Radiocarbon Dating Laboratory code; CM, Canterbury Museum; CRA, conventional Radiocarbon Age. Owing to small sample sizes, d13C was measured on prepared graphite using the AMS spectrometer. The radiocarbon dates have therefore been corrected for isotopic fractionation. All isotope values measured on bone gelatin.
