Here is a nice pair of unusual echinoderms. These are Oklahomacystis tribrachiatus paracrinoids from the Ordovician of Oklahoma. These primitive echinoderms are very 3-dimensional and exhibit great detail. They both have extremely ornamented plates that are very nicely articulated. The paracrinoids are nicely spaced on the large plate of fossiliferous limestone. These are both great examples of this bizarre Ordovician echinoderm.
