Non-Concordance of Radiocarbon and Amino Acid Racemization Deduced Age Estimates on Human Bone

Abstract

Radiocarbon determinations, employing both decay and direct counting, were obtained on various organic fractions of four human skeletal samples previously assigned ages ranging from 28,000 to 70,000 years on the basis of their D/L aspartic acid racemization values. In all four cases, the ¹⁴C values require an order of magnitude reduction in age.
