The above cystoid is an excellently preserved Glyptocystitid Rhombiferan specimen. As you can see, the hand drawing at the top of this page is not an exaggeration. This really is a strange looking creature. What appears to be eyes are actually pore rhoms.

This is a nearly complete specimen of the Rhombiferan Cheirocystis fultonensis was found that the base of the Kope Formation Fulton Beds (left and right sides shown above). It is missing the stem. The specimen has not been prepared and so is covered with matrix. As of this writing, less than a dozen complete specimens of this species have been found and so each specimen is of scientific importance. This one was found by Bill Heimbrock in March 2001. Note the ambulacra exposed at the top of the specimen.
