Onondaga Limestone (NYDou;2)USGS

The Selinsgrove Limestone Member of the Needmore Formation of central PA is the direct equivalent of the Onondaga Limestone in NY. The Onondaga is generally subdivided into four members across NY: Edgecliff, Nedrow, Moorehouse, and Seneca. These four members are directly equivalent to those of the Buttermilk Falls Limestone of eastern PA.

Ordovician period of the Ozark Plateaus in Arkansas

The formation commonly breaks with conchoidal fracture and is noted for not supporting lichens to any great extent. Fossils are common to some upper beds, most notably Tetradium coral fragments and colonies. The lower contact of the Plattin Limestone is disconformable. The formation may reach as much as 250 feet thick, but is usually much thinner.
