NYSM locality TRQ-32, Top of Wolfville Mbr. ( of the United States)

Also known as Tri States Quarry, Whitehall, Washington Co.

Where: Washington County, New York (43.5° N, 73.4° W: paleocoordinates 31.8° S, 67.5° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Wolf Hollow Member (Tribes Hill Formation), Skullrockian (487.5 - 482.3 Ma)

• "uppermost Wolf Hollow Member, upper Tribes Hill Formation; top surface" (Kröger & Landing, 2007)

• bed-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; intraclastic, shelly/skeletal grainstone and stromatolitic bindstone

• The Wolf Hollow member is "interpreted as a latest highstand systems tract. These intervals were earlier thought to be an intertidal facies (Braun and Friedman, 1969), but Landing et al. (1996) demonstrated that the environment was wave-dominated and somewhat deeper, with frequent storm beds that indicate episodically high-energy deposition. Thus, the peaks in cephalopod abundance and diversity discussed below indicate shallow, but not intertidal environments and a more restricted marine facies than that of the uppermost Sprakers, Van Wie, and lower Wolf Hollow members." (Kröger & Landing, 2007)
• "massive, cliff-forming [...carbonates...] with its characteristic thrombolites in an echinoderm-intraclast matrix" (Kröger & Landing, 2007);

•"identifiable trilobites, brachiopods, and ellesmeroceratoids were recovered

•from inter-thrombolite echinoderm grainstones" (Landing et al., 2003)

Size classes: macrofossils, mesofossils

Preservation: cast
