This is a nice, enrolled Isotelus maximus from the famous trilobite beds at Mt. Orab Ohio. It it was outstretched it would be around 2" long. It has beautiful shell preservation unlike many specimens who's shell flakes badly during collection and is restored. Both the genal spines are missing, but you rarely get enrolled Isotelus inflated like this, they are typically crushed.

Isotelus maximus is the the official state fossil of Ohio.
