Temperature calibration of amino acid racemization: Age implications for the Yuha skeleton
D/L of aspartic acid ranged from 0.52 to 0.56 for femur samples of the Yuha skeleton. Subsurface temperature measurements made at the burial site indicate average annual temperature is 18°C and diagenetic temperature is 21.6°C. These data and a relation derived for the dependence of the aspartic acid rate constant on diagenetic temperature indicate an age of 23,600. The result is consistent with14C and230Th dating of calcrete found coating the bones.
