Principle of carbon dating
intcal extended radiocarbon dates beyond the limit of dendrochronology by basing it on "matched uranium series and radiocarbon dates on fossil corals, coupled with radiocarbon-dated organic material from laminated marine sediments in the Cariaco Basin, Venzuela" (Mike Walker, ). They apparently increased the effectiveness of radiocarbon dating by basing their calibration charts on radiocarbon-dated coral and sediment layers!Everyone assumes that dates that follow the word "radiocarbon" are accurate, precise and sure. The basic principle of radiocarbon dating is that plants and animals absorb trace amounts of radioactive carbon-14 from carbon dioxide (CO2) in the atmosphere while they are alive but stop doing so when they die.The carbon-14 in a sample decays at a steady rate after it dies, and thus works like a clock. Doesn't that give accurate dates of "prehistoric" civilizations?
Carbon dating is the ultimate benchmark of the evolutionary dating world.
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).
