In this article we shall discuss the principles behind amino acid dating (also known as racemization dating); we shall discuss how it ought to work, and why it often doesn't.

At the present time there is insufficient knowledge concerning the effective average racemization rate in a fossil as a function of time to justify dependence on D/L ratios for a quantitative determination of age.

The survival of amino acids in fossils from the Paleozoic era and the trend for the apparent racemization rate constant to decrease with conventional fossil age assignment raise a serious question concerning the accuracy with which radioisotope age data have been used to represent the real-time history of fossils.

These effects restrict amino acid chronologies to materials with known environmental histories and/or relative intercomparisons with other dating methods.

Temperature and humidity histories of microenvironments are being produced at ever increasing rates as technologies advance and technologists accumulate data.

Well to some extent maybe but it reveals a very simplistic understanding of dating techniques and of science itself.
