Isotelus maximusDescription: In proportion, I am sure that Isotelus are found in very low numbers compared to the ubiquitous Flexicalymenes. This one, in fact, is the first Mt. Orab Isotelus ever acquired by Pangaea Fossils. It appears to be in very good condition. It would make a nice addition to any Mid-Western Ordovician collection. Isotelus maximus is the state fossil of Ohio.
