Amino acid racemization biostratigraphy refers to using the ratio of right-handed (D) to left-handed (L) amino acids (D/L value) preserved in sediment or fossils to determine the age of sedimentary deposits including the duration of time recorded in sedimentary deposits. This can be done by direct comparison of D/L values to determine relative ages or by using calibrated D/L values to estimate ages in calendar years.
