Scientists would use index fossils to determine the age of rock in a layer. Index fossils are fossils that are known to have existed during a specific time period and can be used as markers to determine the age of the rock layer in which they are found. By identifying index fossils in a rock layer, scientists can establish the relative age of that layer compared to other layers containing similar index fossils.
