Homoiostelea

      Homoiostelea is an extinct class of Upper Cambrian to Lower Devonian echinoderms. They are characteristic by feeding arm and a complex stem composed in part of more than 2 series of plates. The thaeca is apparently assymetrical. They partially reminiscent morphologically simillar (but bilaterally more symetrical) Stylophora. Both classes were considered as representatives of group of advaced echinoderms Calcichordata (certain equivalent of early chordates).
