Where: Wayne County, Mississippi (31.7° N, 88.6° W: paleocoordinates 32.0° N, 82.2° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Mint Spring Formation, Rupelian (33.9 - 28.1 Ma)
• The Mint Spring Formation consists of fossiliferous sands that lie disconformably above the estuarine 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 environment 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.
