An index fossil is a fossil that is useful for dating and correlating the age of the rock layers in which it is found. These fossils are typically from organisms that were widely distributed but only existed for a relatively short geological time period.
Therefore, from the discovery of an index fossil, the geologist can determine **the age of the rock**.
