                is a very rare species from an obscure location. Montana trilobites
                are amongst the hardest to acquire from the western states. Generally
                when found, they are missing their free cheeks. This one has
                both,
              firmly attached. Only the genal spine on the left side of the cephalon
                is missing on this specimen.
