This is a very nice, high quality fossilized Starfish in matrix from Morocco.  The Starfish measure approximately 1 5/8″ in a fossilized matrix measuring 4″ x 3 3/4″ x 3/4″ thick.  This Starfish fossil is from the Ordovician Period some 450 to 510 million years ago and was found in the Kataoua Formation in Morocco.  A very nice addition to your fossil collection.
