Mosley Creek, route 55 bridge (Paleocene of the United States)

Where: North Carolina (35.3° N, 77.4° W: paleocoordinates 36.0° N, 59.4° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Moseley Creek Formation (Beaufort Group), Thanetian (59.2 - 56.0 Ma)

• 0.3 m below the top of the outcrop or about 0.6 m below the Paleocene-Eocene contact exposed south of the bridge. The occurrence of Globorotalia aequa Cushman and Renz, G. pseudomenardii Bolli, G. pseudobulloides (Plummer), and Globigerina triloculinoides Plummer indicates that the sample is Thanetian in age and is part of the P4 planktonic foraminiferal zone. Formerly Beaufort Formation.

• bed-level stratigraphic resolution

Environment/lithology: offshore; lithified, burrowed, nodular, phosphatic, argillaceous sandstone

• Planktic foraminifera and calcareous nannoplankton are common. Along with the fine grain size, phosphate nodules, and lack of structures, suggests a fairly offshore environment.
• Clayey and silty fine to very fine sand, phosphate grains common, calcareous nodules, burrows. Lithified based on nautilid preservation as molds.

Size class: macrofossils

Preservation: mold/impression
