Here is a very unusual fossil echinoderm. This is a beautiful Spinadiscus lefebvrei edrioasteroid from the Ordovician of Morocco. Edrioasteroids were primitive echinoderms which consisted of a flexible theca composed of numerous polygonal plates. This edrioasteroid has very good natural orange color and excellent contrast. The fossil has extremely fine detail preserved - the plate structure and "star" are very easily seen. The edrio is well showcased on the natural plate of sandstone. This is a very fine example of this unique fossil echinoderm from Morocco.
