          |  Description: 
              An attractive and rare association of two Altiocculus drumensis 
              on a trimmed plate. The primary specimen is large, 3D and well preserved. 
              Note the pustules covering the body and an amazingly numerous 30 
              segments of the species. The eyes are present. The right side of 
              the cephalon is fully intact, the left side is folded under. The 
              secondary specimen is a molt and missing its free cheeks. This plate 
              was professionally prepared using air abrasion by Dave Comfort. 
              There has been no restoration or enhancement.
