True Starfish FossilsDescription: This matrix displays an unusual starfish found in the Ordovician deposits of El Kaid Errami. Intact starfish specimens are quite uncommon in the fossil record. This specimen is a member of the Asteroidea, or True Starfish. Unlike the brittlestars, true starfish have Starfish Asteroideano 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 unusual in that it has 6 arms rather than the usual 5. Most likely it had lost one and when regrown two arms took its place like Hydra from mythology. It is seen here as a fine part/counterpart specimen.
