          |  Description: 
              A spectacular example of this rarely-offered spiny trilobite, this 
              one is stunning. Dorypyge is the patronymic genus of the Dorypygidae, 
              a sought-after family of trilobites from the western United States. 
              While you may be able to find a less expensive example, you would 
              be hard-put to find one better prepared than this one. Many hours 
              of exacting work went into this specimen, but you can see it was 
              well worth it.
