 Description:
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  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 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.
