Summary

[edit]
Description
English: Fossiliferous limestone in the Ordovician of Indiana, USA.

This limestone is part of 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 fossils shown here are mostly brachiopods. Other recognizable fossils and fossil fragments include solitary rugose corals (Grewingkia canadensis) and bryozoans.

Stratigraphy: talus derived from the Waynesville Formation or Liberty Formation, Richmondian Stage, upper Cincinnatian Series, upper Upper Ordovician

Locality: Southgate Hill Outcrop - roadcut along Rt. 1, southwest of Cedar Grove & north of St. Leon, southeastern Franklin County, southeastern Indiana, USA (vicinity of 39° 20' 14.26" North latitude, 84° 57' 09.77" West longitude)
