Eurypterid-Associated Biota of the Williamsville Member, Buffalo, New York (Silurian of the United States)

Where: New York (42.9° N, 78.9° W: paleocoordinates 30.3° S, 40.8° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Williamsville Member (Bertie Formation), Pridoli (418.7 - 416.0 Ma)

• member-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; dolomite

• "Probably BA 1, as indicated by the brachiopods and Leperditia, but more open marine conditions as indicated by the presence of additional, fully marine organisms. Ruedemann (1925) suggested that the Bertie was a 'lagoonal deposit' formed behind coral reefs, with salt hoppers indicating hypersaline conditions."

•2003:05:03 SEP environmental call; this unit is a mixture of peritidal and lagoonal facies; based on this description, lagoonal is appropriate here

• "Dolomite, with crossbeds, and salt hopper casts."
