This is a rare UK trilobite. It is a very scarce Cryptolithus instabilis from Maen Gwyn, Powys, Wales. This trilobite is complete and wonderfully articulated. The textbook pitted fringe is intact and nicely showcased. The bug is very well centered on the natural block of dense shale. This is easily one of the rarest trilobites found at this location, and it is a very fine example indeed.
