I’m with Jack — this looks like a Phacopid trilobite, perhaps even Phacops. In WV these are found in Middle Devonian rocks like the Marcellus Shale and the Mahantango Formation. Mahantango and Marcellus trilobites lived about 385 million years ago.

But the Eastern panhandle of WV….aren’t all those shales metamorphosed? Maybe not all, but all the ones I have seen were metamorphosed! No chance of fossils in a rock that has been through that much heat and pressure.
