English: Calcite crystal-covered fossil in the Ordovician of Kentucky, USA.
The rocks of the Upper Ordovician Cincinnatian Series in the Ohio-Kentucky-Indiana tristate area were deposited in relatively shallow marine facies. The Cincinnatian succession is mostly interbedded limestones and shales. Most of the limestones are event beds (= tempestites), deposited during ancient storms. Seen here is a calcite crystal-covered fossil (burrow or nautiloid?) eroded from the Bellevue Limestone, a shallow water, limestone-rich Cincinnatian unit. Robust orthid brachiopods are common in the Bellevue Limestone - principally Hebertella occidentalis and Platystrophia ponderosa (also known as Vinlandostrophia ponderosa). Stratigraphy: float from the Bellevue Limestone, Maysvillian Stage, middle Cincinnatian Series, Upper Ordovician Locality: Maysville West upper cut - roadcut on the northwestern side of Rt. 62/Rt. 68, just south of bridge over Lawrence Creek & south of the Harsha Bridge over the Ohio River, northern Kentucky, USA (~vicinity of 38° 40’ 05.75" North latitude, 83° 48' 07.48" West longitude) |
