Starfish (asteroids) and brittle stars (ophiuroids) are known from Ordovician, Silurian, Devonian, and Mississippian rocks of Ohio. They are rare fossils but an outcrop in the Cuyahoga Formation (Mississippian) of Cuyahoga County contained approximately 4,500 individuals of Strataster ohioensis per square meter.
