Rocky Point Quarry, Castle Hayne Limestone (Lutetian) (Eocene of the United States)

Where: Pender County, North Carolina (34.4° N, 77.9° W: paleocoordinates 34.5° N, 66.2° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Comfort Member (Castle Hayne Formation), Lutetian (47.8 - 41.3 Ma)

• member-level stratigraphic resolution

Environment/lithology: deep subtidal shelf; lithified grainstone and lithified packstone

• This fossil association suggests that the Castle Hayne Limestone was deposited on a distal inner middle shelf (30–100 m water depth) in a subtropical to warm temperate climate setting.
• The Castle Hayne Limestone is dominated by bryozoan-echinoderm grainstone ⁄ packstone.

Size class: macrofossils

• 92 of 340 brachiopod specimens drilled (27.1%)

Collection methods: surface (float)
