Fusulinids fossils
Fusulinids are conspicuous fossils in the blocks of flint in this area. The flint is underlain by unfossiliferous limestone. In southern Ohio this horizon is referred to as the Ferriferous limestone, because of its association with the Ferriferous ore which was the foundation of the iron industry in Ohio in the last century.
