Description: The Fezouata and Tafilalt biotas provide an exceptional representation of exquisitely-preserved Ordovician life from Morocco. Both show parallels to the olderOphiuroidea Burgess Shale fauna of the Cambrian of Canada. This is a fine example of a member of the Ophiuroidea, or Brittlestars. The Brittlestars and True Sea Stars shared a common ancestor in the Ordovician. Intact starfish specimens are quite uncommon in the fossil record. This one probably died in an environment in which the water had a gentle current as all the arms are oriented in what must have been the downstream direction.
