          |  Description: 
              Unusual example of a member of the Order Proetida, Family Otarionidae 
              with many fine details present. While most frequently known in the 
              trade as “Otarion”, this one is actually a member of 
              the genus Cyphaspis. The most diagnostic features of this taxon 
              are the high stalked eyes, elongated spines, and granulose bulbous 
              cephalon. This one has been prepared in such a way that matrix has 
              been removed from beneath each spine to afford a most dramatic display 
              specimen, a time-consuming, delicate task.
