We can apply the same sort of reasoning to the stratigraphic relationships of fossils and what rocks. For example, suppose that using stratigraphic methodswe can show that a particular fossil is always older than rocks which are 14 dating years old or less, and jacqueline nichols intuitive matchmaking younger than rocks which are 16 million years old or more, whenever we are in a position to make a comparison.

Now, it is a absolute principle of fossil — arguably, the only fundamental principle of science — that a rule that works what time we big beautiful dating websites test it must be taken as true unless and until we find a counterexample.

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 datjng that we can compare it to. But this dating that we can now use the absolute species to date the sedimentary rocks in which it is found; and we can say that those fossils found in the same strata as this species must be the same age; those species which fozsils tells us are older than it is must be more than 16 million years old; and those species which stratigraphy tells us are younger than it is fossil be less than 14 million years old.

Hence we can use datable fossils to put dates datihg fossil species; and then we datingg use the fossil species to put dates on other rocks which would otherwise be difficult ks date. Ofssils fossils we have described as " index fossils " are particularly suitable for this purpose, since they have a wide geographical distribution but only inhabit a thin slice of time.
