3.3" Fossil Starfish (Petraster?) & Edrioasteroids - Morocco
This is a 3.3" wide, Ordovician aged starfish of the genus Petraster that's associated with several edrioasteroids of the species Spinadiscus lefebvrei. It comes from the Tioririne Formation near El Kaid Rami, Morocco. The specimen shows an amazing amount of detail and the natural, orange coloration is due to the oxidization of iron pyrite.
