Fossil record
The chronological order of rock layers is usually determined by their order in an undisturbed sequence of strata. According to the principle of superposition, the oldest layers would be found at the bottom and the youngest layers at the top. In disturbed rock layers (those that have been folded, uplifted, or generally disrupted by tectonic forces), the determination must be made based on the presence of index fossils, comparison to undisturbed strata or radiometric dating.
