Here is an unusual double plate of edrioasteroids from the Ordovician of Canada. There are two very good specimens of Isorophusella incondita on the slab. Edrioasteroids were primitive echinoderms which consisted of a flexible theca composed of numerous polygonal plates. These edrioasteroids exhibit fine detail. The outer rings of small plates are beautifully displayed, and the ambulacral plates are also well defined. The cream-colored fossils contrast nicely with the grey matrix. The edrios are well presented on the rectangular slab of hard limestone. This is a very fine double plate of these uncommon echinoderms from Canada.
