Ordovician Starfish (Petraster?) Fossils - Morocco

This is a pair of Ordovician aged starfish (Petraster?) fossils from the Tioririne Formation near Kaid rami, Morocco. The orange coloration is natural and due to the oxidization of iron pyrite. The largest of the starfish is 1.85" wide. There is some restoration to the starfish on the left.

It comes with an acrylic display stand.
