A single charcoal sample was submitted for identification and AMS radiocarbon dating from the Genevieve Lykes Duncan Site (41BS2615) on the 02 Ranch, approximately 25 miles south of Alpine in Brewster
Includes conventional and calibrated ages (in years before present, using the SHCal13 calibration curve with an offset of -21 ± 6 years) plus errors. Modelled weighted mean (in calendar years C.E.) ca
The calibration of radiocarbon ages into calendar ages is based on Calib 6.1.1 (Stuiver and Reimer, 1993) and INTCAL09 (Reimer et al., 2009) and on a 2 uncertainty.
All 14C dates are rounded to decades. Planktic plateau boundaries were either defined at or in between single 14C ages of the records. All 14C dates are rounded to decades. Planktic plateau boundaries
