An index fossil is a fossilized remains of an organism that was widespread but existed for a relatively short geological time period. These fossils are used by geologists and paleontologists to date and correlate the age of rock layers and to identify specific time intervals in the geological timeline. Because of their distinctive features and temporal specificity, index fossils help in understanding the relative ages of different strata in sedimentary rock formations. Examples include species like Trilobites and Ammonites, which are often found in various locations around the world.
