CR-R, New Bern Quarry (Eocene of the United States)

Where: Craven County, North Carolina (35.1° N, 77.0° W: paleocoordinates 34.9° N, 68.9° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: New Bern Formation, Priabonian (38.0 - 33.9 Ma)

• "New Bern Formation" of Powell & Baum, 1982. Crassatella alta/Chlamys cawcawensis bivalve or Periarchus lyelli echinoid zone. Spring Garden member is latest Claibornian (latest middle Eocene) according to Weaver& Ciampaglio (2003). PJW: I switched this to New Bern. I also changed it to Priabonian from Bartonian. The upper part of the Crassatella alta - Chlamys cawcawensis zone is Priabonian, so this is not inconsistent with the original paper.

• group of beds-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, shelly/skeletal, sandy grainstone

• Lithology suggests high-energy shallow subtidal environment
• Sandy, pelecypod-mold biomicrosparrudite that disconformably overlies the castle hayne limestone.

Size class: macrofossils

Preservation: mold/impression
