Where: Wayne County County, New York (43.1° N, 77.1° W: paleocoordinates 27.6° S, 43.3° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Glenmark Shale Formation (Clinton Group), Wenlock (433.4 - 427.4 Ma)

• formation-level stratigraphic resolution

Environment/lithology: offshore; lithified, silty, calcareous mudstone and lithified, calcareous siltstone
