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: surface (float), mechanical, sieve,
• Approximately 1 gallon of weathered surface sediments were collected and and processed in the lab with a 1 mm seiv.
