MGS 1, Town Creek, Jackson (Eocene of the United States)

Where: Hinds County, Mississippi (32.3° N, 90.2° W: paleocoordinates 33.1° N, 81.3° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: NP17 - NP18 nannofossil zone, Moodys Branch Formation (Jackson Group), Bartonian (41.3 - 38.0 Ma)

• NP17 - NP18 nannofossil zone

• group of beds-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; unlithified, gray, silty claystone

• Sediment reworked in the offshore environment by wave turbulence and burrowing organisms. A deeper facies than the northern shelf, which contains cross-bedding, suggesting an offshore-transition environment.
• Most of the fossils that Dockery reports are from the Clay Bed: "A silty, dark to light gray clay containing lenses of well-preserved fossils and irregular, cylindrical burrows preserved as clay-ironstone bodies."

Size class: macrofossils
