2.5" Prone Isotelus Trilobite - Mt. Orab, Ohio

This is a nice, 2.5" long Isotelus maximus from the famous Mt. Orab, Ohio trilobite locality. Isotelus maximus is the state fossil of Ohio.

There have not been many good Isotelus being found in the quarry in recent years. This specimen is laid out perfectly prone which is unusual. There is some restoration along fractures in the shell, but this is almost always the case with Isotelus from Mt. Orab.

About Trilobites

Trilobites are an extinct class of marine arthropods that thrived for nearly 270 million years, from the early Cambrian to the end of the Permian period (around 521 to 252 million years ago). They are one of the most successful and diverse groups in the history of life, with over 25,000 described species spanning a wide range of sizes, shapes, and ecological niches. Known for their distinctive, segmented exoskeletons, trilobites provide invaluable insights into the evolutionary history of arthropods and the dynamics of ancient marine ecosystems.
