Crinoids Mass MortalityDescription: These crinoids come from the Ordovician deposits of Morocco. They differ but little from Sinoeocrinus from the Cambrian of China, showing that the crinoids had not yet undergone the extensive radiation that was soon to come. Both sides of this plaque contain fully-articulated specimens, making for an excellent display piece..
