I fear that you take far too much for granted. We only know that carbon dating works on the items we already know the age of. If we do not know the age of the item, we cannot know whether the test is giving us accurate results. You can extrapolate, but you cannot be sure the extrapolation is yielding accurate results. In other words, it is a guess.
That's completely untrue. Carbon-14 is Carbon-14, regardless of the fossil in which it may be found.
