Oneida Creek, southeast of Kenwood (Silurian of the United States)

Where: New York (43.0° N, 75.6° W: paleocoordinates 30.2° S, 39.5° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Vernon Formation, Ludfordian (425.6 - 423.0 Ma)

• Middle Vernon Formation

• bed-level stratigraphic resolution

Environment/lithology: lagoonal; lithified, dolomitic, gray, green, calcareous shale

• "The 'Camarotoechia' and lingulids plus the Lepterditia strongly suggest a BA 1 assignment."

•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

• "Gray to gray-green, calcareous shale in a sequence of green, red, and gray shale and dark-colored dolomite."

Size class: macrofossils
