MGS Loc. 108b - Mint Spring Bayou [Mint Spring Fm] (Oligocene of the United States)

Where: Warren County, Mississippi (32.4° N, 90.9° W: paleocoordinates 32.7° N, 84.3° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Mint Spring Formation, Rupelian (33.9 - 28.4 Ma)

• The Mint Spring Formation consists of fossiliferous sands and clays that lie disconformably above the estuarine clays of the Forest Hill Formation. The sands of the Mint Spring Formation are moderately clean and often show cross-bedding. These sands indicate a near-shore shelf enviroment and have a macrofauna dominated by bivalves.

• formation-level stratigraphic resolution
