Eurypterid-Associated Biota of the Vernon Formation, Pittsford, New York (Silurian of the United States)

Where: New York (43.1° N, 77.5° W: paleocoordinates 29.2° S, 41.4° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Vernon Shale Formation, Ludlow (427.4 - 423.0 Ma)

• formation-level stratigraphic resolution

Environment/lithology: lagoonal; black, gray shale and dolomite

• "The abundant lingulids and Leperditia suggest a BA 1 assignment, but some of the other elements are consistent with a BA 2 assignment; more information needed about the actual associates of the eurypterids."

•2003:04:06 SEP environmental call based on liimited lithologic description and overall context of Salina Formation (to which Vernon has been refered to as member by some authors). NOTE: stratigraphically near evaporites and within a restricted basin; periodically experiences more normal marine conditions with increased tidal flushing

• "Dark gray to black shale and dolomite, with abundant gypsum."
