Summary
| Description |
Fossiliferous limestone in the Mississippian of Kentucky, USA. Limestone is a calcareous, biogenic sedimentary rock. It is principally composed of calcium carbonate (CaCO3) in the form of calcite (many geologically young limestones are aragonitic). Numerous specific varieties of limestone exist. The type seen here is a fossiliferous limestone, composed of whole + fragmented fossil shells and skeletons, mixed with fine-grained sediments (e.g., calcareous mud). Recognizable fossils here include brachiopods and crinoids. Stratigraphy: Raney Creek Member, Slade Formation, Chesterian Series, Upper Mississippian Locality: Bighill Mountain Outcrop - Route 421 roadcut through Bighill Mountain, ~county line between Rockcastle County and Madison County, south of the town of Bighill, east-central Kentucky, USA (vicinity of 37° 31’ 24.89” North latitude, 84° 12’ 28.15” West longitude) |
