The Cuyahoga Formation is a geologic formation in Ohio. The age of the formation is difficult to determine, because of a lack of diagnostic fossils. Roughly, the formation dates from the Late Kinderhookian (354.8 to 350.8 million years ago) to the Middle Osagean (347.7 to 344.5 million years ago).[1] Eight members are recognized, among them the Orangeville Shale, Sharpsville Sandstone, and Meadville Shale.[2]
It preserves fossils dating to the Mississippian subperiod of the Carboniferous period.[3]
