Where: New York (43.0° N, 75.6° W)
• Paleocoordinates: 25.8° S, 68.6° W (Wright 2013)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Vernon Formation, Ludfordian (425.6 - 423.0 Ma)
• Middle Vernon Formation
• bed-level stratigraphic resolution
Environment/lithology: lagoonal; lithified, dolomitic, gray, green, calcareous shale

•2003:04:06 SEP environmental call based on liimited lithologic description and overall context of Salina Formation (to which Vernon has been refered to as member by some authors). NOTE: stratigraphically near evaporites and within a restricted basin; periodically experiences more normal marine conditions with increased tidal flushing
Size class: macrofossils
