4.8" Detailed Ordovician Starfishs (Two Species) - Morocco

This is a large fossil starfish (Ophiura sp) next to a smaller starfish (Petraster) from the Tioririne Formation of Morocco. It's ordovician in age or approximately 450 million years old. The bright orange coloration is natural and due to the oxidization of iron pyrite. There are several repaired cracks in the rock.

It comes with an acrylic display stand.
