This is a nice US Trinucleid trilobite. It is a cool Cryptolithus bellulus from the classic site at Swatara Gap, Pennsylvania. This specimen was collected by Steve Hess in 1990. 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. The rest of the trilobite also has excellent detail - one LONG genal spine is even preserved. The bug's rust-orange coloration is naturally striking. This is a very nice example of this beautifully-fringed trilobite, well fossilized on a natural plate of shale.
