How reliable is carbon dating keysa machado dating
C." When comparing radiocarbon dates with dates derived from tree rings, known as dendrochronological dating, the dates only agree accurately as far back as A. 640, and only generally well back to the time of Christ.Anything further back and the dates are as much as 800 years off.But the new data, combined with what Reimer calls a 'real sense of necessity' among team members to resolve the debates, won the day" (January 15)."Fancy statistical treatments" that didn't even resolve all of the discrepancies?
But they still have to verify their calibrations with samples of known dates. Radiocarbon dates can only be trusted up until the record left by trees can back them up.
"Despite the uncertainties associated with the older part of the age range, the international radiocarbon community has recommended that intcal 98 be used as the basis for calibration for the time being" (emphasis mine throughout).
So even though it is less reliable and has some serious problems, scientists ignore that and still use it.
Doesn't that give accurate dates of "prehistoric" civilizations?
Carbon dating is the ultimate benchmark of the evolutionary dating world.
