6.5" Carpoid (Dendrocystites?) Fossil Plate - Morocco
These are large, 3.5" and 3.3" long carpoids probably of the genus Dendrocystites from the Lower Ordovician deposits near Kaid Errami, Morocco. They have beautiful orange coloration due to the oxidization of iron pyrite. Carpoid are an extinct echinoderm (same Phylum as starfish, urchins, etc) that attached themselves to the sea floor by stalks. The rock measures 5.6" by 4.8".
