Figure 3

Calibrated radiocarbon dates from Cross Creek Layer 9 grouped into a single phase in OxCal46. (A) Using the: (A) pre-AD 1950 marine ΔR of − 7 ± 45 14C yrs19; (B) ΔR of − 15 ± 24 14C years based on archaeological data collected in this paper; and (C) Age calibrated using the black coral dataset (‘New Marine’ calibration curve). The extended sequence analysis of layers 7 and 9 is presented in Fig. S2. Vertical dashed lines are the 68% prob. maximum age ranges of the marine dates (Wk-21363 and Wk-21355). Wk-21642 is a terrestrial date. The red line represents the calendar age of the Kaharoa tephra44. Green band = marine calibration curve (either Marine13 in Fig. A and B or ‘New Marine’ in Fig. C). Blue band = terrestrial calibration curve (SHCal13).
