Three Ordovician Starfish (Petraster?) Fossil - Morocco

This is a plate containing three Ordovician aged starfish (Petraster?) from the Tiouririne Formation near Kaid rami, Morocco. The orange coloration is natural and due to the oxidation of iron. There are a couple of repaired cracks running through the rock. The reverse side features a few additional marine fossils.

It comes with an acrylic display stand.
