the basis of D/L aspartic acid and D/L glutamic acid was presented in Table 5. In Fig. 3 we presented these ages by linear regression and this way it also presented the correlation of ages estimated by anthropological and by the two D-amino acid contents. It was evident from this figure that this correlation of ages estimated by the traditional and the new D-aspartic acid content methods was extremely close. When comparing the results of anthropological age estimation to those of the method based on amino acid racemisation the value of r exceeded 0.9 with both Table 4.
