Ordovician Edrioasteroid (Spinadiscus) Fossil - Blekus, Morocco

This is a fossil Edrioasteroid from the Ordovician aged Kataoua Formation near Blekus, Morocco. The orange coloration of the fossils is due to oxidization of iron pyrite which originally replaced the fossils.

Edrioasteroids are an extinct class of echinoderms that lived from the Ediacaran until the Permian, about 300 million years ago. The living animal would have resembled a pentamerously symmetrical disc or cushion.
