Passage Gulf (CUGM collection) (Silurian of the United States)

Where: New York (43.0° N, 75.1° W: paleocoordinates 31.3° S, 38.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Phelps Member (Fiddlers Green Formation), Pridoli (423.0 - 419.2 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; lithified, dolomitic, gray lime mudstone

• The stratigraphic sections and the fossil content suggest that it was deposited in a near-shore marine setting, but the evaporites and casts of halite pseudomorphs with sides of up to 30 cm suggest the environment was far from normal marine; hypersalinity must have prevailed throughout most of the depositional history of the Bertie Group.

Size class: macrofossils

Preservation: adpression

Collection methods: Repository: New York State Museum (formerly Cornell University Geological Museum)
