Source: WordNetA calibration curve is used by taking the radiocarbon date reported by a laboratory, and reading across from that date on the vertical axis of the graph. Source: Internet
Archaeologists' most precise determinations at present suggest that this radiocarbon age is equal to roughly 13,200 to 12,900 calendar years ago. Source: Internet
Bayesian statistical techniques can be applied when there are several radiocarbon dates to be calibrated. Source: Internet
Creatures living at the ocean surface have the same mainC ratios as the water they live in, and as a result of the reduced mainC / mainC ratio, the radiocarbon age of marine life is typically about 440 years. Source: Internet
Although the peat encasing Lindow Man has been radiocarbon dated to about 300 BC, Lindow Man himself has a different date. Source: Internet
As radiocarbon dates began to prove these ideas wrong in many instances, it became apparent that these innovations must sometimes have arisen locally. Source: Internet
