1.9" Ordovician Brittlestar (Petraster) & Edrioasteroids - Morocco

This is a 1.9" wide, Ordovician aged brittlestar of the genus Petraster. It comes from the Kataoua Formation near Blekus, Morocco. The specimen shows an amazing amount of detail and the natural, orange coloration is due to the oxidization of iron pyrite. There are also a number of Edrioasteroids (Spinadiscus lefebvrei) associated with it. Comes with an acrylic display stand.

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.
