This is an excellent Trinucleid trilobite. It is a complete Cryptolithus bellulus from the classic site at Swatara Gap, Pennsylvania. This specimen was collected by Steve Hess in 1986. This type of trilobite is known for the unusual pitted fringe that encircles the entire front of the trilobite - this specimen has this feature wonderfully displayed (hard to see in photo). Part of both genal spines are also preserved, which is quite uncommon. The rest of the trilobite also has excellent detail. And the bug's natural orange coloration is just awesome. This is a very cool example of this colorful, beautifully-fringed trilobite from this classic closed site.
