This is a nice 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 intact. The rest of the trilobite also has excellent detail. The bug's natural dark-orange coloration is quite striking. This is a distinct example of this beautifully-fringed trilobite from this closed site.
