Archaeological Radiocarbon Dates

(Updated 08/12/12)



For cases in which conventional radiocarbon ages are available, calibrated dates are calculated using the program Calib 5.0.1, 5.0.2, or 6.0 for consistency (M. Stuiver, P. J. Reimer, and R. Reimer, http://calib.qub.ac.uk/calib/calib.html ). The one- and two-sigma ranges are specified as the extreme values of those ranges, without regard to gaps within the ranges. When uncalibrated ages are not available, the calibrated ages or dates given in the original sources are listed within parentheses.

The reservoir effect is factored in for marine shell using the delta-R regional averages for western Baja California (238 64), southern Gulf of California (253 18), central Gulf of California (406 34), or northern Gulf of California (546 35) in the Marine Reservoir Correction Database (Paula Reimer, http://radiocarbon.pa.qub.ac.uk/marine/ ).
