Where: Washington County, Missouri (38.0° N, 90.8° W: paleocoordinates 22.8° S, 86.3° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Eminence Formation, Trempealeauan (492.5 - 485.4 Ma)

• Note: authors give Rasettia magna for the trilobite zone, but that is much too old for Eminence. So, either this is Potosi or even Derby Doe Run, or it's a different trilobite zone.

• formation-level stratigraphic resolution

Environment/lithology: dolomite

Size classes: macrofossils, mesofossils

Preservation: replaced with silica
