With a few important exceptions, living organisms keep all their amino acids in the "L" configuration. The results provide a compelling case for applicability of amino acid racemization methods as a tool for evaluating changes in depositional dynamics, sedimentation rates, time-averaging, temporal resolution of the fossil record, and taphonomic overprints across sequence stratigraphic cycles. Fluorine absorption Nitrogen dating Obsidian hydration Seriation Stratigraphy.

When an organism dies, control over the configuration of the amino acids ceases, and the ratio of D to L moves from a value near 0 towards an equilibrium value near 1, a process called racemization.
