The unit name usage by the U.S. Geological Survey (USGS) is the Oriskany Sandstone.[5] Butts (1940) stated that the Oriskany Sandstone "corresponds exactly with the Ridgely Sandstone" and that the rules of stratigraphic nomenclature dictate that the name Oriskany Sandstone should be applied to these strata.[6]
