Howellella-Plecatrypa-Fenestrate Bryozoan Community of the Rochester Shale at Ni (Silurian of the United States)

Where: Niagara County County, New York (43.1° N, 79.1° W: paleocoordinates 27.0° S, 44.8° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Lewiston Member (Rochester Shale Formation), Wenlock (433.4 - 427.4 Ma)

• Middle Rochester Shale (Lewiston Member, Submember E) 'Bryozoan Beds'

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; lithified, calcareous shale and lithified, sandy limestone

• relatively shallow depositional environment, affected by frequent storm action (average storm wave base) but slightly below normal wave base. An outer BA 3 (offshore shoal) assignment is indicated.

•

•2003:04:06 SEP environmental/tectonic/sequence calls based on field knowledge familiarity with stratigraphic context.

• This high diversity assemblage occurs in interbedded calcareous shales and thin calcarenitic limestones.
