The Upper Ordovician Cincinnatian Series is a critical upper Katian reference succession. Previously, six 3rd-order depositional sequences (C1 to C6) have been recognized and frequently used as. Certain Upper Ordovician (Cincinnatian) crinoid pluricolumnals from Kentucky, Ohio and Indiana, derived from the disparids Cincinnaticrinus spp., have rounded terminations reminiscent of some. A bewildering profusion of lithostratigraphic names have been applied to the type Cincinnatian Series, largely because of the complex intertonguing of the lithofacies and their similarity to one another. Sequence stratigraphy offers a way to select a consistent set of lithostratigraphic names, which are shown to the left. The Ordovician Period began about million years ago and ended about million years ago. These are the oldest rocks in the state that are exposed at the surface, in southwestern Ohio along the axis of a positive structural feature known as the Cincinnati Arch or Platform, which formed in the Ordovician.

fossils from Ohio's Ordovician rocks define life of this geologic period, and the rocks of this region, the Cincinnatian Series, serve as the North American Upper Ordovician Standard. Furthermore, in the late 's, Ordovician rocks in the subsurface in northwestern Ohio were the source of the first giant oil and gas field in the country.   The Upper Ordovician strata of the Cincinnati Arch region in southern Ohio, Kentucky, and southwestern Indiana were selected for study (Fig. 1), because the nearly undeformed strata can be traced over very long distances bed by bed using a network of relatively new road etic overprint is weak or absent, so that the calcareous substrates are mostly well enough preserved to . Thousands of lingulid brachiopods were found clustered beneath hundreds of individual valves of the strophomenid brachiopod Rafinesquina in the Upper Ordovician of Ohio. This association suggested a relationship between the two brachiopods, but the nature of this relationship was unclear. We utilized serial thin sectioning to examine these brachiopods and to determine the origin of the bed in.
