Howellella-Striispirifer-Ramose Bryozoan Subcommunity of the Rochester Shale at (Silurian of the United States)

Where: Niagara County County, New York (43.1° N, 79.1° W: paleocoordinates 28.4° S, 43.0° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Lewiston Member (Rochester Shale Formation), Wenlock (428.2 - 422.9 Ma)

• Middle beds of the Rochester Shale, Lewiston Member, Submember D

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; lithified, gray, calcareous mudstone and lithified, silty, sandy carbonate

• 2003:04:06 SEP environmental/tectonic/sequence calls based on field knowledge familiarity with stratigraphic context.
• Lithology is predominantly medium gray, calcareous mudstone but thin calcarenite and calcisiltite beds indicate distal effects of storms. This indicates a bathymetric setting within storm wave base. Fossils occur in basal lags in the storm beds in intervening mudstones.
