          |  One
                of the most desired of Utah giant trilobites is the Hemirhodon
                amplipyge.
              This one, like the majority found, is an internal mold, having
                no calcite skin. It has been lightly enhanced to give the specimen
                presence. The only flaw is the missing tip of the right genal
                spine.
              To the best of my knowledge, the quarry from which these come has
                not been active for years.
