Summary
| Description |
English: Platystophia brachiopod in the Ordovician of Kentucky, USA.
This fossil is eroded from Upper Ordovician fossiliferous limestones of the Ashlock Formation, which is correlative with the famous Cincinnatian outcrop belt in the Cincinnati, Ohio area. I've seen two or three asserted members identified for this area, so I'm not sure about the sub-formation level stratigraphy at this site. The fossils are similar to what's seen in the Maysvillian and/or Richmondian Stages of the type Cincinnatian. Observed fossils here included silicified stromatoporoids, brachiopods (including Platystrophia ponderosa - also known as Vinlandostrophia ponderosa - and Hebertella), ramose bryozoans, encrusting sheet bryozoans, bivalves, gastropods, nautiloid cephalopods, and corals. The rocks range from micrites (lime mudstones) to wackestones to packstones. Classification: Animalia, Brachiopoda, Articulata (also known as "Rhynchonelliformea") Stratigraphy: Ashlock Formation, Cincinnatian Series, Upper Ordovician Locality: Paint Lick Elementary School Outcrop - roadcut along (new) Route 52, across the road from Paint Lick Elementary School, near the town of Point Leavell, Garrard County, Kentucky, USA.
