Middle and Upper Devonian marine strata are examined in quarries and natural exposures at six localities in Erie and Huron counties in north-central Ohio. The formations studied are the Lucas Dolomite, Columbus Limestone, Delaware Limestone, Plum Brook Shale, Prout Limestone, and Huron Shale. Lithologies and fossil contents suggest depositional settings ranging from open marine to tidal flat. Biostratigraphy indicates correlation of Columbus and Delaware limestones with the Onondaga Limestone and Marcellus Shale, respectively, of New York and with the Detroit River Group and Dundee Limestone, respectively, of the Michigan Basin.
