1" Wide, Unprepped Enrolled Isotelus Trilobite - Mt. Orab, Ohio

Wide, Unprepped Enrolled Isotelus Trilobite - Mt Orab, Ohio #248620

This is an enrolled, unprepped Isotelus maximus from the famous trilobite beds at Mt. Orab Ohio. If it were outstretched it would be around 1.6" long. Portions of the trilobite are missing across the pygidium and cephalon. It comes with the rock it was found in allowing it be display in or out of the rock.

Isotelus maximus is the the official state fossil of Ohio.

Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
