Wilmington City quarry (Eocene of the United States)

Where: New Hanover County, North Carolina (34.3° N, 77.9° W: paleocoordinates 34.1° N, 68.8° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Castle Hayne Formation, Bartonian (41.3 - 38.0 Ma)

• LITHOSTRATIGRAPHIC RELATIONSHIPS: Castle Hayne Limestone. AGE: Eocene, according to Miller (1947); Bartonian, according to Kier (1980). STRATIGRAPHIC POSITION: From unknown position in section.

Environment/lithology: deep subtidal ramp; lithified limestone

• ENVIRONMENT: The Castle Hayne Limestone was deposited in an open, normal salinity environment between 30 m and 100 m in water depth. Comfort Member contains cross-bedded intervals, suggesting some energy, consistent with deep subtidal environment.
• LITHOLOGY: Three facies in ascending stratigraphic order: phosphate pebble biomicrudite, bryozoan biosparrudite, bryozoan biomicrudite. LITHIFICATION: Lithified, on the basis of facies description and specimen preservation.

Size class: macrofossils

Preservation: cast, mold/impression

Reposited in the USNM

• COLLECTORS: Unknown, multiple. REPOSITORY: USNM.
