Index fossils are useful to paleontologists because they are easily recognizable, widespread, and existed for a relatively short period of time. This allows scientists to date the rock layers in which they are found, helping to establish the relative ages of different strata. Additionally, index fossils help correlate rock layers from different locations, aiding in the reconstruction of Earth's history.
