Otisville eurypterids (Silurian to of the United States)

Where: New York (41.5° N, 74.5° W: paleocoordinates 28.9° S, 43.5° W)

• coordinate based on nearby landmark

When: Shawangunk Formation, Llandovery to Llandovery (443.4 - 423.0 Ma)

• formation-level stratigraphic resolution

Environment/lithology: marginal marine; lithified, black shale and lithified, conglomeratic sandstone

• Considered by Smith (1970) to be a proximal braided stream deposit. [GSA Bull. 81:2993-3014.] 2003:04:06 SEP tectonic/stratigraphic information supplied on the basis of regional stratigraphic context and lithological description. Only applies if Llandoverian age is correct. Later age assignment changes context in larger sequence architecture.
• Black, arenaceous shale and massive, crossbedded, conglomeratic sandstone (eurypterids in shale).

Size class: macrofossils

Preservation: trace
