内容記述 In measuring radiocarbon ages, carbon and nitrogen stable isotope ratios of fossil bone samples, only one section in all skeletons in generally used as an individual. In order to investigate on whether we could really obtain the representative value by analyzing only one section of bone or not, we compared gelatins extracted several skeleton sections in the same individual of amino acid compositions and radiocarbon ages. The samples used were fossil human bones of three people excavated from the Yuigahama-minami archaeological site, Kamakura, Japan. The C/N ratios of these bones were 3.1-3.4 and their gelatin yields were more than 0.7 wt% in almost bone sections. A previous study showed that all bone sections have roughly the same δl3C and δ15N values although vertebras tend to have about 1‰ higher values than the others in both of δ13C and δ15N. The amino acid compositions of the bone sections of the Kamakura individuals have been studied by gas chromatography to investigate the cause of 1‰ higher values in vertebra. The experimental data show that bone gelatins have essentially the same amino acid composition as in modern bone gelatin. The important thing is that different bone sections showed almost the same amino acid compositions. This similarity suggests that the fractionation of stable isotope ratios between different bone sections in an individual could be caused not by extraneous contaminants and diagenetic alteration during burial but likely by metabolism before death. This study suggests the possibility that spines reflect any information accumulated in shorter period prior to death than other skeletal sections, as with skins and hairs. Furthermore several bone sections show the same radiocarbon ages within errors. In other words, any bone section can be used for 14C dating. A measured result of one skeleton section could be adopted as a representative value of whole individual under current technical level.
