Fairton - Kirkwood Formation (Miocene of the United States)

Where: Cumberland County, New Jersey (39.4° N, 75.2° W: paleocoordinates 39.6° N, 70.8° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

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

• No lithostratigraphic details or stratigraphic relationships provided in text. Equivalent in age and slightly older than the Calvert Formaiton of Maryland and Virginia. Overlain by the Cohansey Sand with a time transgressive contact, Kirkwood Formation is Burdigalian-Langhian in age.

• member-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified sandstone

• 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

• Collections reposited in ANSP, USNM and USGS collections.
