Locality 1. Bakers Station (Ordovician of the United States)

Also known as Articulate Brachiopods in the Central Basin

Where: Davidson County, Tennessee (36.4° N, 86.7° W: paleocoordinates 26.8° S, 61.7° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Fernvale Formation, Richmondian (449.5 - 443.7 Ma)

• Calcarenite bed near top of Fernvale. The Arnheim Formation is limited to the northwest flank of the Nashville Dome. The overlying Fernvale Formation crops out in a discontinuous belt along the north, west, and south sides of the Cenral Basin.

• bed-level stratigraphic resolution

Environment/lithology: deep subtidal; shelly/skeletal, silty lime mudstone and red, yellow lime mudstone

• In the Arnheim Formation, micritic limestone contains abundant skeletal material, finely comninuted bioclastics, intraclasts, and silt- and clay-sized particles. Calcarenites characterize the Fernvale Formation. A thin interbedded shale and limestone facies can be recognized at the top of the Fernvale. Brachiopods common in crinoidal biosparite.

Size class: macrofossils

Preservation: original calcite
