Where: Rankin County, Mississippi (32.2° N, 90.2° W: paleocoordinates 32.5° N, 83.7° 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 mostly of fossiliferous sands that lie disconformably above theestuarine clays and sands 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
Environment/lithology: offshore; lithified, conglomeratic, calcareous conglomerate and wackestone
Size class: mesofossils
Preservation: original aragonite, original calcite
Collection methods: bulk, mechanical,
• bivalves only.
