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

Where: New York (43.1° N, 76.2° W: paleocoordinates 31.0° S, 38.6° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Williamsville Member (Bertie Formation), Pridoli (423.0 - 419.2 Ma)

• "Williamsville Member (=Oxbow)"

• member-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; dolomite

• "Probably BA 1 ... 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; unit is a mixture of peritidal and lagoonal facies; based on this description, lagoonal is appropriate

• "dolomitic waterlime"
