Also known as Starbuck Road; Rochdale Fm., "Fort Ann Fm."; Washington Co.
Where: Washington County, New York (43.4° N, 73.4° W: paleocoordinates 31.9° S, 67.6° W)
• coordinate estimated from map
• small collection-level geographic resolution
When: Rochdale Formation (Beekmantown Group), Stairsian (485.4 - 478.6 Ma)
• "upper Rochdale Formation";
•"As concluded by Landing & Westrop (2006, p. 967), the Rochdale Formation is the senior synonym of the ‘Fort Ann Formation’, a unit for which a type section was never specified and which was named for a village that is actually located on Late Ordovician synorogenic flysch. Further north in western Vermont, the Bascom Formation (Cady, 1945) includes three divisions that indicate lateral equivalency and junior synonymy with the upper Tribes Hill, Rochdale and Fort Cassin formations (Landing, Westrop & Van Aller Hernick, 2003)." (Kröger & Landing, 2008 p. 492)
• member-level stratigraphic resolution
Environment/lithology: shallow subtidal; stromatolitic, intraclastic reef rocks and intraclastic limestone
Size class: macrofossils
Preservation: cast
Collected by R. H. Flower; reposited in the NYSM
• "Most of the cephalopods discussed herein were collected in the 1940s by R. H. Flower during his tenure at the New York State Museum (NYSM). Flower (1955, 1956, 1964a, 1976) repeatedly referred to this material in the NYSM Paleontology Collection [...]" (Kröger & Landing, 2008 p. 491). At the Starbuck Road locality "R. H. Flower collected a few cephalopods (8 specimens, 2 remaining in NYSM Paleontology Collection)." (ibid. p. 493).
