Ordovician Echinoderm Fossils AssociationDescription: This plate displays a fine starfish found in the Ordovician deposits of El Kaid Erram in association Echinodermatawith a pair of Edrioasteroids. Intact starfish specimens are quite uncommon in the fossil record. This fine specimen is a member of the Asteroidea, or True Starfish. Unlike the brittlestars, true starfish have no demarcation between the arms and the ventral body, and move by means of tube feet rather than by the sinuous movements of the arms. The starfish is quite 3-D in appearance making for a dramatic display piece. The Edrioasteroids were an extinct class of echinoderms that went extinct during the Permian, a time that saw nearly 90% of all species wiped out. The main feature of the disc-like body was the presence of five arms, indicative of its echinoderm heritage. These arms could be either straight or curved and served as a means of transporting food to the central mouth.
