Where: Wayne County, Mississippi (31.0° N, 88.7° W)
• Paleocoordinates: 34.6° N, 75.8° W (Wright 2013)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Forest Hill Formation, Rupelian (33.9 - 28.1 Ma)
• The upper part of the Forest Hill Formation consists of estuarine clays and sands which locally contain a marine fauna. In Wayne county at localities 75a and 88a, numerous, wel preserved fossils were collected from sand lenses in this interval. Also present in this interval are leaf fossils which occur along beddind planes in the clay. These estuarine and marine sediments are the initial stage in the marine transgression of the Mint Spring seaway.
• formation-level stratigraphic resolution
Environment/lithology: offshore; poorly lithified, gray, silty, sandy claystone and sandstone
Size class: mesofossils
Preservation: original aragonite, original calcite
Collection methods: bulk, mechanical,
• bivalves only
