Granton Quarry (Triassic of the United States)

Also known as Belmont-Gurnee Quarry, North Bergen

Where: Hudson County, New Jersey (40.8° N, 74.0° W: paleocoordinates 15.4° N, 19.3° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Ewing Creek Member (Lockatong Formation), Norian (221.5 - 205.6 Ma)

• The base of the section appears to be 38-46 m above the contact with the Palisade sill. At least 7 beds are fossiliferous.

•"the Lockatong Formation is composed entirely of repetitive sedimentary cycles caused by the rise and fall of lakes controlled by climate changes...".

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine - large; black, gray, calcareous siltstone

• "Division 2 is a thinly bedded, laminated to microlaminated (laminae < 1 mm) red, green or gray to black, sometimes organic-carbon-rich, siltstone, claystone, or carbonate showing few or no signs of desiccation. In its best-developed form, division 2 is black and microlaminated and contains abundant and well-preserved fossil fish, arthropods, and small reptiles"

Size class: macrofossils

Reposited in the AMNH
