| 説明 | Fossiliferous limestone in the Ordovician of Ohio, USA.This fossiliferous limestone surface is in the famous Cincinnatian Series of the tristate area of Ohio-Kentucky-Indiana. Rocks in the Cincinnatian were deposited in relatively shallow marine facies during the Late Ordovician. The Cincinnatian succession is mostly interbedded limestones and shales. Most of the limestones are event beds (= tempestites), deposited during ancient storms.The fossil shells seen here are strophomenid brachiopods. The twig-shaped fossils are bryozoans.Stratigraphy: upper Waynesville Formation, Richmondian Stage, upper Cincinnatian Series, upper Upper OrdovicianLocality: talus piece along the cut wall of Caesar Creek Lake's emergency spillway (between Clarksville Road and Roaring Run), northeastern Warren County, southwestern Ohio, USA |
