Osgood Member | Indiana Geological & Water Survey

As recognized by Foerste (1897), the Osgood consisted of lower and upper shaly units, an intervening middle carbonate unit, and in many places a basal dolomitic limestone (Rexroad, 1986). These lithologies are gradational, and the units have limited lateral extent in southeastern Indiana (Rexroad, 1986).
