Where: Ohio (41.0° N, 82.0° W: paleocoordinates 31.1° S, 30.2° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Chargin Shale Formation, Late/Upper Famennian (364.7 - 360.7 Ma)

• Listed as Late Famennian

• formation-level stratigraphic resolution

Environment/lithology: deep subtidal shelf; poorly lithified, pyritic shale and lithified siltstone

Size class: macrofossils

Collection methods: Collection only includes brachiopods and bivalves, but text says brachiopods are "most abundant...with bivalves as a minor constituent of the total fauna" and formation is generally "sparsely fossiliferous"
