Faunal succession is also used to compare fossils of organisms in different areas on the Earth.Since many plants and animals have large habitats, this can be very useful in helping to date sediment layers of interest.

Effective index fossils have several characteristics—they are widespread, distinctive, abundant, and limited in geologic time.This can be a challenging concept to understand, but if you imagine a basin where sediment is deposited, this principle states that the sediment will be equally deposited in this area until there is no more sediment or until the sediment reaches the edge of the basin or another barrier.Using a mental picture to understand this concept can be very helpful.A simple way to remember this term is to think that an inclusion represents something being included in the rock that wouldn’t have been otherwise.The law of lateral continuity states that the deposition of sediment is continuous unless there is a barrier or subsequent changes in the landscape break up layers.
