What is the purpose of absolute dating

So in this case we would have to conclude that this fossil species is between 14 and 16 million years old wherever we find it, even in those cases where there are no datable rocks that we can compare it to.

Now, it is a fundamental principle of science — arguably, the only fundamental principle of science — that a rule that works every time we can test it must be taken as true unless and until we find a counterexample.Precise isotopic ages are called absolute ages, since they date the timing of events not relative to each other but as the time elapsed between a rock-forming event and the present.Absolute dating by means of uranium and lead isotopes has...So, you might say that the 'full-life' of a radioactive isotope ends when it has given off all of its radiation and reaches a point of being non-radioactive.When the isotope is halfway to that point, it has reached its half-life.There are three main advantages of using fossils for dating in this manner.
