2.9" Isotelus Trilobite - Mt. Orab, Ohio
This is a nice, 2.9" 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 mostly prone with the tail just slightly tucked. Both genal spines are present with the tip of the right one partially free of the shale. There is about 3% shell restoration in a few matches where it fractured during collection.

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.
