Where: Montgomery County, New York (42.9° N, 74.3° W: paleocoordinates 31.7° S, 68.5° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Tribes Hill Formation (Beekmantown Group), Skullrockian (487.5 - 482.3 Ma)

• "riberirid zone" (!?) (Flower, 1964)

•"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)" (Kröger & Landing, 2007, J. Paleont. 81(5))

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; limestone

• "The Tribes Hill Formation is a deepening-shoaling, unconformity-bounded, carbonate-dominated sequence laid down on a wave dominated shelf (Landing et al., 1996; Landing, 1998)." (Kröger & Landing, 2007)
