Where: Cape May County, New Jersey (39.4° N, 75.0° W: paleocoordinates 39.6° N, 70.6° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Shiloh Marl Member (Kirkwood Formation), Early/Lower Miocene (23.0 - 16.0 Ma)

• No geologic or paleoenvironmental data reported in text. Deposited in a sublittoral to nearshore environments
• Fossiliferous sandstone and quartzite.

Size class: macrofossils

Reposited in the USNM
