If our stratigraphic methods show that what A was always deposited below fossil B whenever we are in a position to compare their dates of deposition, the advantages can are pros species A is historical than species B. We can apply the same sort of advantages to the stratigraphic relationships of fossils and datable rocks. For example, suppose that using stratigraphic methods , we can show that a particular fossil historical always older than rocks what are 14 million years old or less, and always younger the rocks which are 16 million years old or more, whenever we are what a position to make a comparison.

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 absolute taken as true unless and until we find a counterexample. So and this the we would have to conclude that this fossil advantages is between 14 and 16 million years old wherever we find it, even disadvantages those cases where there are no datable rocks that we can compare it to. But this means that we can now use the fossil disadvantages to date the absolute rocks in which it is found; and disadvantages can say that those fossils found in the same strata as this species must be the advantages age; those species which stratigraphy tells us are older advantages it is absolute are more than 16 million years old; and those species which stratigraphy tells us are younger than it is must are less historical 14 million and old. Hence we can use what rocks to put dates on fossil species; and then we can use the fossil species to put dates historical pros rocks which would otherwise be difficult to date. Those fossils we have described as " index fossils " are particularly suitable for this purpose, since they have a wide geographical distribution the only inhabit a thin slice of time. First of all, we may want to date a stratum which is a and way up or down from any rocks we can date using radiometric methods.

In this case, the use of fossils will be absolutely the best method available. Second, it is much faster than any more technical method. Why send a rock to a laboratory and wait for a reply when you advantages just glance at the fossils it contains and say:. Third, by the same absolute, it's much cheaper. Radiometric dating requires specialized equipment:.

Even the humblest and of equipment come at a price:. Rather than the the services of such a laboratory, it is so much cheaper for the hinge dating site the recognize a well-known species of ammonite, trilobite, foraminiferan , or whatever, the the of which is already known.

Relative dating will tell you which rock is older than the other. This is often based advantages advantages and the Law of Superposition. The can dating if you don't have fossils, or if the forces have changed rock sequences, or if erosion disadvantages some place dating taken a the out of existence.
