USGS 5094-CO. Devils Hollow Road south of Buttimer Hill (Ordovician of the United States)

Where: Franklin County, Kentucky (38.2° N, 84.9° W: paleocoordinates 27.0° S, 63.2° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Plectodina tenuis conodont zone, Grier Limestone Member (Lexington Limestone Formation), Chatfieldian (453.8 - 451.0 Ma)

• "Float 45 ft above Macedonia Bed."

• bed-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, nodular, shelly/skeletal limestone

• "This member apparently was deposited in shallow, well-aerated, moderately agitated water of normal salinity. The nodular bedding is probably due to the activity of burrowing organisms.... deposited in water 50 ft or less deep."
• "The Grier Limestone Member consists predominantly of thin- and irregularly bedded to nodular-bedded, poorly sorted, fossiliferous limestone. It ranges from 100 to 180 ft.... The most common bedding assemblage in the Grier Limestone Member consists of sets, about 0.5 ft thick, of nodular-bedded, fossiliferous calcisiltite to very poorly sorted, fossiliferous calcarenite with minor shale partings, alternating with slightly irregular, 0.4-ft-thick beds of poorly sorted, fossiliferous calcarenite."

Size class: macrofossils
