Three Ordovician Starfish (Petraster?) Fossils - Morocco

This is an association of three Ordovician aged starfish (Petraster?) from the Tiouririne Formation near Kaid rami, Morocco. The largest starfish measures 2.4" across. The orange coloration is natural and due to the oxidation of iron. There are a few repaired cracks throughout the rock for stability of the overall specimen with some restoration along the cracks.

It comes with an acrylic display stand.
