Where: Berkeley County, South Carolina (33.3° N, 80.1° W: paleocoordinates 33.4° N, 79.5° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Raysor Formation, Late/Upper Pliocene (3.6 - 2.6 Ma)
• Local section name: Cross. Basinal/regional section name: Berkeley.
•From Mercenaria level, Raysor Marl (late middle Pliocene age, ~3.6 Ma). Raysor Marl is laterally equivalent to the lower Goose Creek Limestone, although older publications suggest it unconformably overlies that unit. The Raysor Marl, as described by Sloan (1907), Cooke (1936), and Weems et al. (1982) is a silty quartz sand. Lithostratigraphically and biostratigraphically equivalent beds are present at the former Raysor Bridge locality, South Carolina. Ecological analysis indicates that the assemblage is Raysor (K-5).
