Nebraska City Section, Clay Pits southeast of Nebraska City (Carboniferous of the United States)

Where: Otoe County, Nebraska (40.7° N, 95.9° W: paleocoordinates 0.4° S, 26.9° W)

• outcrop-level geographic resolution

When: Pillsbury Shale Formation (Wabaunsee Group), Virgilian (303.7 - 298.9 Ma)

• Most of the gastropods were originally reported from the “Dyas” by Geinitz, which Meek (1867) equated with Marcou’s Unit C. Condra (1927) notes that this is the Table Creek Shale, which is now known as the Pillsbury Shale Formation. (Whew....)

• formation-level stratigraphic resolution

Environment/lithology: marine; argillaceous shale

• Most of the formation is one sort of argillaceous shale or another.
