Trilobites: The Index Fossil There are many thousands of known species of trilobite fossils found worldwide. Trilobites are considered to be good index fossils because they evolved so rapidly, and this allows geologists the ability to date the rocks in which the trilobites are found. The discovery of trilobites is second only to the discovery of dinosaurs, and new species of trilobites are still being discovered today.
