Samples collected by numerous investigators, primarily K.R. Lajoie (US Geological Survey), G.L. Kennedy (USGS and Los Angeles County Museum of Natural History), J.F. Wehmiller, Univ. of Delaware. Some samples from existing USGS collections also included. Samples collected and prepared between 1975 and 1981. Samples prepared and analyzed at the University of Delaware, Newark DE, Lab PI John F. Wehmiller. Some samples analyzed by D. J. Blunt, USGS and at the University of Alberta. Analyses at UC San Diego are compiled here and included in Kern and Rockwell (1992). Locality number is from Kennedy et al. 1982 Figures 1 and 2 Locality name is from Kennedy et al., 1982 Figure 1 Locality designation lists field numbers or museum locality numbers: LACMIP = Los Angeles County Museum of Natural History HSU = Humboldt State University M = US Geological Survey CAS = California Academy of Science UCLA = Univ. California Los Angeles SDSU = San Diego State University Pretreatment: Fragments cut from shell valves; surface cleaning with dental tools; dilute HCl and distilled water wash; air dry AA fraction="amino fraction" THAA = total hydrolyzable amino acids; FAA = free amino acids (zero hydrolysis time) Hydrolysis procedure: 6N HCl 22 hours 105 deg C (for THAA only) Bleach: No Instrumental programming: GC temperature program; HPLC buffer gradient Blank corrections: no Response factors: no D/L values reported as peak height ratios Lab Code UDEL= University of Delaware; USGS = U. S. Geological Survey, Menlo Park, CA; UCSD = Univ. California San Diego Sample ID = identity of specific shell analyzed Analytical method: GC = gas chromatography, used for multiple amino acids; HPLC used for determination of A/I values Subsample ID = usually the same as sample ID; repeat fragments of same shell will have unique identification Ratio type = Peak Height ratios used for all results from GC; peak area ratios assumed for all results for HPLC D/L values are reported as the means of multiple chromatograms, usually at least 3. For GC results, in most cases sample derivatives were analyzed using more than one GC column. Samples selected for analysis were chosen because they appeared to be the most robust specimens among those available, In most cases, samples were not whole valves. Abraded, rounded, or chalky fragments were avoided where possible, and multiple shells from each collection were analyzed in almost all cases. No data screening procedures have been applied. No interlab sample comparisons were made during the period of these analyses. Information on sample quality (fragment, whole shell, abraded, chalky, etc.) will be compiled for a future version of this datafile.

Ages generated in this fashion are highly model dependent and require estimates of integrated long-term diagenetic temperatures. We present here an alternative, empirical approach to aminostratigraphy in which we plot amino acid enantiomeric ratios versus latitude (for localities along the Pacific coast of the United States), and generate isochronal correlations by connecting data points of geographically proximal localities that have similar D:L ratios and zoogeographic aspect. Isochrons are calibrated at a few localities by independent radiometric dates. The diagenetic temperature effect on racemization is reflected in the slope of the isochrons, but the need to quantify temperature is eliminated.
