Summary

Description

Fossiliferous limestone in the Pennsylvanian of Ohio, USA.

The Pottsville Group is a Pennsylvanian-aged cyclothemic succession in eastern Ohio that contains nonmarine shales, marine shales, siltstones, sandstones, coals, marine limestones, and chert ("flint"). The lower Pottsville dates to the late Early Pennsylvanian. The upper part dates to the early Middle Pennsylvanian. The Lower-Middle Pennsylvanian boundary is apparently somewhere near the Boggs Member (?).

The outcrop shown above is the Lower Mercer Limestone, a laterally persistent, marine fossiliferous limestone unit in the Pottsville Group. Common fossils in this unit are crinoids and brachiopods.
