They also have hard body parts which are bones, teeth, shells and thus, evolved rapidly. Ammonites: The fossil of ancient marine animals is said to be known as an ammonite index fossil. Lastly, it is limited to the geological time scale. Different fossils work well for sediments of different ages; trilobites, for example, are particularly useful for sediments of Cambrian age. The architecture of geological time includes ages, epochs, periods, & eras, which index fossils helped to determine. : During the Paleozoic Era (540 to 245 mya); they were common.
