An extinction occurs when a species dies out and there are no members of the
species left on Earth. The fossil record shows an extinction when a species is no longer
found in sedimentary rock layers. For example, trilobites were once very common
marine arthropods. They disappeared from the fossil record after the Permian-Triassic

A mass extinction happens when whole groups of related species die out at
about the same time. Mass extinctions appear to be caused by large changes to the
environment. When so many organisms die, there are many new opportunities for
surviving species to use ecosystem resources. They then thrive and change over time.
The numbers of new species found in the fossil record after each mass extinction
eventually increases over time.
