Also known as collection KY-4; Shideler localities 3.51 B and 3.51 B2; Lake Cumberland; Rowena

Where: Russell County, Kentucky (36.9° N, 85.1° W: paleocoordinates 27.6° S, 62.2° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Leipers Limestone Formation, Maysvillian (452.0 - 449.5 Ma)

• "Tetradium biostrome exposed along river bank."

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; shelly/skeletal, gray wackestone

• " [...] The inferred environment of deposition was a shallow-marine, mixed carbonate and clastic bottom that becomes lower energy with time, the lithofacies becoming more fine-grained upsection. [...] normal marine environment"
• "coralline biostromes [...comprising a...] diverse fauna of brachiopods, bryozoans, the coral Tetradium, gastropods, nautiloids, pelecypods, ostracodes, and trilobites.";

•"dense, dark-gray fossiliferous wackestone"

Size class: macrofossils

Preservation: recrystallized, replaced with calcite
