Different types of fossil dating
Geologists also use fossils for what’s called biostratigraphic correlation, which allows researchers to match layers of rock in different locations by age based on how similar the fossils in each rock layer are.This information can be used to help understand when different layers of rock were formed even when large distances separate them (reference 1).Environmental interpretation, or understanding how the Earth has changed over time, is another area where fossils supply invaluable evidence.The type of fossil found in a particular location tells us what kind of environment existed when the fossil was formed.
For example, if you find fossil marine animals like brachiopods in the sandstone in your backyard, you know that there must have once been an ocean where your house now stands (reference 1).
Fossils also have practical and commercial applications.
