Where: Cherokee County, Oklahoma (35.8° N, 94.8° W: paleocoordinates 11.9° S, 36.2° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Pitkin Formation, Chesterian (339.4 - 318.1 Ma)

• The Pitkin formation is the uppermost Chesterian unit preserved in this part of the Ozarks. The Mississippian/Pennsylvanian unconformity cuts into the top of the Pitkin in this region and is overlain by the Morrowan age Sausbee Formation.

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified, shelly/skeletal grainstone

Size classes: macrofossils, mesofossils

Collected by N. A. Heim in 2005

Collection methods: bulk, mechanical,

• A bulk sample of approximately 2 gallons was collected and fossils were removed in the lab by crack out.
