Pierce - Wilson, 1949 (Ordovician of the United States)

Where: Tennessee (35.5° N, 86.5° W: paleocoordinates 28.1° S, 66.4° W)

• basin-level geographic resolution

When: Pierce Limestone Formation, Blackriveran (457.3 - 449.6 Ma)

• formation-level stratigraphic resolution

Environment/lithology: lithified, peloidal, shelly/skeletal packstone and wackestone

• Geologic information based on field work of S.M. Holland and M.E. Patzkowsky
• interbedded limestone and mudstone. limestone: thin to medium beds of peloidal to skeletal wackestone, packstone, grainstone, and calcisiltite. some beds with tool marks, planar lamination and hummocky cross-stratification. mudstone: calcareous, thin-bedded to partings.

Preservation: original calcite, replaced with calcite
