The improved fluorine analysis method by ion chromatography was applied to the fossil human bones excavated from the Shiraho-Saonetabaru Cave site on Ishigaki Island, which were dated back to the Late Pleistocene. This study presents the first systematic results on individual variation of F/P ratios of fossil bones using less than 1 mg samples. In addition to the burial period, the F/P ratio was governed by the local difference in seepage water circulation, because dripping water in a cave slowly flowed through the sediment and fluorine accumulated in the bone from the water. The F/P ratios provide a powerful tool for elucidating the burial situation and subsequent depositional environment. The average F/P ratio was well correlated with the 14C age of the samples. The present method can be practically applicable as a rough chronological classification of the Holocene and Pleistocene groups of human bones at this site. The only exception was the lower F/P values of the Pleistocene human skeleton belonging to Shiraho No. 4, which is thought to have been placed in a narrow space under the fallen rocks.
