Abstract:
Radiocarbon and calibrated ages and D/L of Aspartic and Glutamic acids of the nine specimens of N. taphria and seven specimens of P. tenuisculpta and used to calibrate the rate of amino acid racemization, plus information on live-collected specimens. Both species were collected at PVL10-50 and OC-50 sites (southern California shelf).
