A fossil will be most useful in finding the absolute age of rocks if it existed for a limited period of time and in a wide area. This is because such fossils are known as index fossils, which are used in biostratigraphy to help date the layers of rock in which they are found. Their limited time range allows for correlation across different geographical areas, making it easier to establish a relative timeline.
