Trilobites were some of the first complex animals to appear in the fossil record and were extremely successful during their time. They existed in the oceans for more than 300 million years, and 20,000 different species have been found. Trilobites eventually went extinct in the great Permian mass extinction 252 million years ago.

They are used as an index fossil in the Ordovician.In 1985, the Ohio government made Isotelus Ohio's official fossil. Isotelus is a trilobite that existed between 430 and 480 million years ago. At this point in time, an ocean covered much of what is now Ohio. Isotelus is evidence of this, as it was a marine organism. A trilobite was an invertebrate creature that had a hard outer shell or skeleton.
