Coolinia-Stegerhynchus subcommunity of the lower Rochester Shale and Herkimer Fo (Silurian of the United States)

Where: New York (43.2° N, 77.6° W: paleocoordinates 27.4° S, 43.7° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Lewiston Member (Rochester Shale Formation), Wenlock (433.4 - 427.4 Ma)

• The collection is from the transitional area between the Lewiston Member of the Rochester Shale and the chronostratigraphic equivalent basal Joslin Hill Member of the Herkimer Formation.

• member-level stratigraphic resolution

Environment/lithology: offshore; lithified, gray, silty, calcareous mudstone and lithified, argillaceous limestone

• 2003:04:06 SEP environmental/tectonic/sequence calls based on field knowledge familiarity with stratigraphic context.
