Santee Portland Cement Co. quarry (Eocene of the United States)

Also known as Holnam Quarry

Where: Orangeburg County, South Carolina (33.3° N, 80.4° W: paleocoordinates 33.3° N, 72.5° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Pregnall Member (Tupelo Bay Formation), Priabonian (38.0 - 33.9 Ma)

• Uhen & Gingerich (2001) state that this is from the Cross Formation. Geisler et al (2005) place the Cross Formation as a member in the Tupelo Bay Formation. Geisler et al (2005) indicate that the Giant Portland Cement quarry is in the Pregnall Member, and Kier (1980) indicates a similar echinoid fauna (Periarchus lyelli), suggesting that this quarry is from the Pregnall Member as well, making it Priabonian.

• member-level stratigraphic resolution

Environment/lithology: marine; shelly/skeletal wackestone and grainstone

• bryozoan biomicrudite/biosparrudite

Size class: macrofossils

Preservation: original phosphate
