This open pit exposes the Pennsylvanian Mecca Quarry black shale, Francis Creek shale, Colchester Coal, and an underclay below the coal- an assembly of strata that have produced world-renowned fossils elsewhere, including Mazon Creek fossils further east and complete sharks from the Mecca Quarry Shale in Indiana. At this location, unfortunately, the concretions are almost all blanks but the black shale does produce isolated fauna including bivalve
