Sea Isle City Well (600-700 ft) - Kirkwood Formation (Miocene of the United States)

Where: Cape May County, New Jersey (39.2° N, 74.7° W: paleocoordinates 39.3° N, 70.3° 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 600 and 700 ft.

• group of beds-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 and USNM. From Richards and Harbison (1942): "The Woolman collectuon contains Miocene fossils between the depths of 490 and 863 ft from a Sea Isle City well. More recently, in 1932, Mr. William Tullner, Jr., obtained a large collection of fossils between the depths of 600 and 700 ft. Many of these were discussed by Pilsbry and Harbison."
