For example, if you find an unknown fossil in the same layer of rock as one of the index fossils, you know your fossil is the same age as the index fossil.

Geologists and paleontologists have used a combination of dating techniques, which are radiometric dating, stratigraphic dating, and index fossils, to determine the approximate age of rocks all over the world.
