Yeah C-14 was thought accurate, because hal lives are constant. But the assumption was that the same amount of carbon was in the air. Now what they do is mathch dates that people know of with the rings in a tree, and use the info they get there as far as amount of carbon and calibrate from there. So carbon 14 is still constant and accurate, but they have had to recalibrate a bunch of dates. |
