Key points: Sedimentary rocks typically occur in horizontal layers called strata. In undisturbed strata, younger layers sit on top of older ones. This is known as the law of superposition. Strata can be cut by other geologic features, such as faults or intrusions. A fault is a crack in Earth's crust.

This combination allows us to identify an index fossil in the strata and have a more precise idea of what window of time we are looking at for the age of the rock unit. Distribution over a large region of the earth; Since most of the Earth is covered in water it is easier for a marine fossil to be considered an index fossil vs land fossils.

'Strata Identified by Organized Fossils, containing prints on colored [sic] paper of the most characteristic specimens in each stratum' (1816-1819), is one of two publications Smith produced as part catalogue/part explanation of his theories when he was forced to sell his collection to the British Museum between 1815-1818.

Fossils and rock layers. Geologists use a geologic timescale to map Earth's 4.6-billion-year history. They study sedimentary rock layers, or strata, and fossils to understand past events. They use the Law of Superposition and the Law of Crosscutting Relationships to determine the relative ages of rock layers.

The 'law of strata identified by fossils' was invented by William 'Strata' Smith from his studies of geological stratification in Britain. This law is based upon his observations that each stratum contained fossils which are peculiar to itself. Such characteristic fossils could thus be used to identify the stratum in locations where it could not be

During this period of confrontation between the proponents of Neptunism and uniformitarianism, there emerged evidence resulting from a lengthy and detailed study of the fossiliferous strata of the Paris Basin that rock successions were not necessarily complete records of past geologic events.
