Locality 8. The woods adjacent to Buffalo (Ordovician of the United States)

Also known as Articulate Brachiopods in the Central Basin

Where: Davidson County, Tennessee (36.1° N, 87.0° W: paleocoordinates 26.9° S, 62.1° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Fernvale Formation, Richmondian (449.6 - 445.5 Ma)

• Calcarenite bed. 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 Central 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
