Amino acid racemization dating of fossil bones

Even the process of preparing a specimen for racemic dating can affect the D/L ratio.

Jeffrey Bada of Scripps Institute of Oceanography announced the "discovery" of a new dating method based on the rate of racemization of amino acids in fossil material.

No such correlation exists for the fractions rich in non-collagenous proteins.

More collagen-rich samples, particularly from bones in older sites, are needed to verify the generality of this trend.

At present, aspartic acid measurements are the most suitable for racemization dating of bone because of their superior analytical precision.
