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

• Paleocoordinates: 36.4° N, 72.8° W (Wright 2013)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Moodys Branch Formation (Jackson Group), Bartonian (41.3 - 38.0 Ma)

• group of beds-level stratigraphic resolution
