6.8" Wide, Enrolled Isotelus Brachycephalus Trilobite - Ohio
This is a large, 6.8" wide, enrolled Isotelus brachycephalus trilobite collected from the Waynesville Formation (Blanchester Series) of Adams County, Ohio. It's nicely positioned on large slab of stabilized shale that measures 11.7 x 7.9". If outstretched, this trilobite would be approximately 10" long.
As is almost always the case with these large Isotelus, the shell was very fractured so it required substantial amounts of repair to put it back into place, and restoration or any missing bits of shell. Both genal spines have undergone repair and restoration.

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.
