They would look for evidence of index fossils, those of certain rapidly evolving creatures that lived during a specific time period. This method is called relative dating. For a closer estimation they would be able to date the rock using radiometric techniques that base its age on the degree of isotope decay . This method would reveal the much more specific absolute age.
An important way that some scientists use to date layers of rocks includes the use of fossils. These fossils are dated using the methods carbon dating and radiometric dating.

Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.

It helps determine the absolute ages of rocks
Geologists determine the absolute age of rocks using radiometric dating techniques, such as carbon dating or uranium-lead dating. These methods rely on measuring the proportions of radioactive isotopes and their decay products in the rocks to calculate how long ago they formed.

Geologists use the geologic column to classify layers of rocks and fossils that make up the Earth's crust.
