NYSM locality 6326 ( of the United States)

Also known as Nelliston, Montgomery Co.

Where: Montgomery County, New York (42.9° N, 74.6° W: paleocoordinates 31.5° S, 68.7° W)

• coordinate estimated from map

• small collection-level geographic resolution

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

• "Wolf Hollow Member (= 'Chuctanunda Creek Member' of unpublished notes of D. W. Fisher that accompanies specimens), upper Tribes Hill Formation"

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified, stromatolitic, intraclastic, shelly/skeletal reef rocks

• 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."
• "massive, cliff-forming [...carbonates...] with its characteristic thrombolites in an echinoderm-intraclast matrix"

Size class: macrofossils

Preservation: cast
