Cape May (unknown depths) - Kirkwood Formation (Miocene of the United States)

Where: Cape May County, New Jersey (38.9° N, 74.9° W: paleocoordinates 39.1° N, 70.5° 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 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. Collections from between depths of 420 and 1140 ft. The characteristic species, Bullopsis integra, of St Marys Fm, is found in the upper level (420-460 ft).

• 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

Collection methods: Reposited in the ANSP collections.
