NYSM locality 5927 ( of the United States)

Also known as Tribes Hill Fm.; east of Comstock, Washington Co.

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

• coordinate estimated from map

• small collection-level geographic resolution

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

• "Trilobite and conodont faunas of the Tribes Hill Formation in New York and Vermont (Westrop et al., 1993; Landing et al., 1996, 2003) indicate that the formation represents only a small interval of the lower, but not lowermost, Ordovician (i.e., lower Tremadocian, upper Skullrockian Stage of Ross et al., 1997) (Fig. 2)."

• member-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

Collected by R. H. Flower in 1945-1947; reposited in the NYSM

• "R. H. Flower collected between 1945 and 1947 at this locality, and 114 specimens are in the NYSM collection"
