Geologists can identify specific sedimentary rocks based on their position in layers and through mineral content and fossilized remains of certain organisms, called index fossils. Index fossils characterize a specific layer over large geographic areas. Scientists can also use radioactive dating to accurately pinpoint the time period of certain things based on the remaining amounts of radioactive isotopes like Carbon-14, Potassium-40, Uranium-235, etc.
