Martin Marietta Rocky Point quarry (base of sequence 3) (Eocene of the United States)

Where: Pender County, North Carolina (34.4° N, 77.9° W: paleocoordinates 34.2° N, 68.7° W)

• coordinate stated in text

• outcrop-level geographic resolution

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

• Recovered from loose bryozoan hash at the base of Sequence 3 (Bartonian) of Harris and Zullo (1991), about one meter or so above the basal phosphate pebble biomicrudite, which represents an initial transgressive lag of the sequence. In this locality, specimens were found closely associated to echinoids of the Kier’s Middle Biozone (Kier, 1980).

• group of beds-level stratigraphic resolution

Environment/lithology: deep subtidal; poorly lithified, shelly/skeletal wackestone

• The biomicrudite facies (Baum, 1980) represent the lower energy and deeper waters of the Castle Hayne embayment during the Eocene transgression (see Feldmann et al., 1998). Quiet conditions in the deepest waters (50-100 m) attained by the Eocene transgression in this area.
• Loose bryozoan hash, biomicrudite

Size class: macrofossils
