Originally described from limited exposures in central Noble County, Ohio, the Noble Limestone Member (Congemaugh Group, Pennsylvanian) has recently been discovered at three additional localities in northern Noble County and eastern Guernsey County. The Noble Limestone Member overlies the fresh-water Ewing Limestone Member and occurs beneath the Rock Riffle Run Limestone Member, at a position about thirty feet below the Ames Limestone Member. Both lithology and fossil content serve to distinguish the limestone and shale of the Noble Limestone Member from that of other Conemaugh marine members. The Noble Limestone Member is now known to occur in an outcrop belt at least 25 miles long and is deserving of recognition as a formal rock-stratigraphic unit.
