Carbon dating makes an animal living 4 thousand years ago (when there was less atmospheric carbon) appear to have lived thousands of years before it actually did.
were switched on, it would only be natural for them to behave according to their individual properties, eventually acquiring stable half-lives of decay, at different rates."We didn't tell them that the bones they were dating were dinosaur bones. The Allosaurus dinosaur was supposed to be around 140,000,000 years.The samples of bone were blind samples.""Of course carbon dating isn't going to work on your Allosaurus bone. So I would expect to get some weird number like 16,000 years if you carbon date a millions of years old fossil.As time progressed each would begin to acquire its slower modern-day stable half-life, but would they all acquire these stable rates in a uniformity which would keep them all in synchrony? If they did, all would give the same ages, you are right.Each would probably arrive at equilibrium at different times.
