Dinosaur Wrote:- wood charcoal is dangerous stuff for dating...... that bit of oak they burned to produce your radiocarbon sample could have come from tthe middle of a 1000-year old tree, so would give you a C14 date 1000 years earlier than when the tree was felled....
Um no...cos the c14 date would be derived from the decayed carbon relative to its half-life, beginning from the the date the tree died, not when it started growing.....C14 dating isn't of the object itself but of the time period since it ceased taking in carbon atoms through photosynthesis....
With peace and consolation hath dismist, And calm of mind all passion spent...
