Where: Montgomery County, New York (42.9° N, 74.4° W: paleocoordinates 31.6° S, 68.6° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Rossodus manitouensis conodont zone, Van Wie Member (Tribes Hill Formation), Tremadocian (485.4 - 477.7 Ma)

• Stratigraphy based on Landing et al (1996, J of P 70:656-680).

• bed-level stratigraphic resolution

Environment/lithology: deep subtidal shelf; lithified, intraclastic packstone and lithified, gray shale

• Based on discussion in Landing et al (1996, J of P 70:656-680).
• "Shales with interbeds of bioclastic and intraclastic packstones and rudstones" (Westrop et al 1993). "[Sample from] recessive, thin interval of dark grey shale and lenticular, intraclast-trilobite-echinoderm limestone...locally dolomitized...weathers buff to tan." (Landing et al 1996, J of P 70:656-680).
