This list of the Paleozoic life of Ohio contains the various prehistoric life-forms whose fossilized remains have been reported from within the US state of Ohio and are between 538.8 and 252.17 million years of age.
Southeastern Ohio was a swamp-covered coastal plain. [4] Ferns and horsetails were among the state's rich flora. [3] Ohio was only about 5 degrees north of the equator. Sand and mud deposited on local river deltas gradually filled in the swamp. Later in the Permian Ohio was subjected to geologic uplift and its sediments were eroded away ...
