Explanation:

The fossils present in a rock exposure or in a core hole can be used to determine the ages of rocks very precisely. Detailed studies of many rocks from many places reveal that some fossils have a short, well-known time of existence. These useful fossils are called index fossils.

Fossils have been used by scientists to determine the dates of rock layers (or strata) that were laid down in succession hundreds of years ago. However, the accuracy and precision of this method depend on several conditions, such as depth, lithology, thickness and abundance of the fossils in that rock.
