The same is true if you take a block away from one of the pyramid's sides, making the rest unstable. The study of rock layers and the layering process. The precision of a dating method depends in part on the half-life of the radioactive isotope involved. Carbon Film Types of Fossils. These fossils are found all over the place!

Carbon, Radiometric Dating and Index Fossils. To be able to distinguish the relative ages of rocks from such old material, and to get a better time resolution than that available from long-lived isotopes, short-lived isotopes that are no longer present in the rock can be used.
