Where: Newton County, Arkansas (35.9° N, 93.0° W: paleocoordinates 12.4° S, 35.2° W)

• coordinate stated in text

• small collection-level geographic resolution

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

• The Hindsville formation is the lowermost Chesterian unit in northern Arkansas and unconformably overlies the Meramecian Boone Formation, but only the Hindsville is exposed in this small outcrop.

• bed-level stratigraphic resolution

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

Size classes: macrofossils, mesofossils

Collected by N. A. Heim in 2007

Collection methods: bulk, mechanical,

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