Cairo quarry (Devonian of the United States)

Where: Greene County, New York (42.3° N, 74.1° W: paleocoordinates 37.8° S, 22.1° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Kiskatom Formation (Hamilton Group), Givetian (387.7 - 382.7 Ma)

• Matten (1975, p. 45):The horizon of the fossils is the Kiskatom Formation placed by Fletcher (1963), in part, into the Plattekill Formation. The latter is equivalent to the marine Skaneateles Formation.

• bed-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; black shale

• Matten (1975, p. 45): The petrifactions were collected from a small, unnamed, local, fine-grained, black , thinly-bedded, shale lens now covered up. The exposure of the lens was no more than 9 m wide and 1 m high at its thickest.

Size classes: macrofossils, microfossils

Preservation: permineralized

Collection methods: chemical, mechanical, peel or thin section,
