Abstract
The authors investigated radiocarbon ages and carbon and nitrogen isotopes in human skeletal remains excavated from the Koh and Ikawazu sites in Osaka and Aichi Prefectures, respectively. Based on excavated pottery and tooth ablation patterns, the Koh population has been regarded as belonging to the Early and Final Jomon Periods. Radiocarbon dating was conducted on Koh skeletal remains to test this age assignment. Koh and Ikawazu human skeletal samples of the Final Jomon Period were analyzed to test the hypothesis that tooth ablation patterns were associated with diet during the period. Collagen was extracted from 28 Koh and 6 Ikawazu bone samples, and was found to be well-preserved in 14 and 4, respectively. Based on results of radiocarbon dating, Koh samples dated to 5440–5990 cal BP, 4410–4520 cal BP, and 2960–3070 cal BP, while Ikawazu samples dated to 2440–3070 cal BP. Among the Koh samples, dietary change was found to be associated to the period. Remains from the Early Jomon Period had higher nitrogen isotope ratios than those from the Final Jomon Period. The Ikawazu samples suggested that those individuals were more dependent on marine resources. The diet of individuals with type 4I and 2C tooth ablation patterns was not significantly different between the Koh and Ikawazu populations. These results suggest that radiocarbon dating of human skeletal remains is essential for proper assessment of dietary reconstruction and temporal patterns in diet.
