Abstract: The authors have adapted a method for determinig the ages of fossils, using the method of isoleucine and other protein amino acid racemizations. By measuring D-allo-isoleucine bone samples over 50.000 years, by the fast racemization amino acid D- and L-versions, followed by ion exchange column chromatography separation with chiralsilica gel layer the ages of bone findings between 5.000 and 50.000 years could be determined with the error of the analytical method (for D-allo-isoleucine ± 5% and ± 15-20% for the other amino acids). A proposal is made for determining bone samples with the approximate age of 1.000 years, with the possible application of amino acids with sulphur and with fatty acids. With 4 tables and 5 figures.
