Twelve species of articulate brachiopods are described from the Elbow Ridge Sandstone of Pennsylvania, Maryland and West Virginia. The sandstone is interpreted as a beach or bar sand facies, and the fossil assemblage is transported and sorted death assemblage. The formation is correlated with the Lower Devonian (Gedinnian) Kalkberg Formation of New York, and the New Creek Limestone of western Maryland. The name Elbow Ridge Sandstone is formally proposed for the unit, and use of the name 'Coeymans Sandstone' for these rocks is discouraged.
