Where: Wyoming County, New York (42.7° N, 78.5° W: paleocoordinates 32.3° S, 26.5° W)
• coordinate estimated from map
• local area-level geographic resolution
When: Hanover Shale Member (Java Formation), Early/Lower Famennian (376.1 - 370.6 Ma)
• Brachiopod bed about 1.4 m above Frasnian-Famennian boundary. Aged based on conodonts present. Lower Palmatolepis triangularis Zone, lowermost Famennian.
• bed-level stratigraphic resolution
Environment/lithology: marine; shelly/skeletal, gray siltstone and gray, green mudstone
•The brachiopod bed is a 5-8 cm thick medium gray siltstone that consists of three fining upward intervals. Brachiopods are ... concentrated in a single 1.0-1.5 cm interval in the middle of the bed, developed in a coarser and more pyritic zone over clay-rich and bioturbated laminae. The pyrite and shell-rich interval overlies a low relief scour surface, indicating a concentration of coarser and denser material during higher energy conditions. the shell-bearing bed [has] low amplitude ripple marks [with] a 6-7 cm wavelength with ripple crests oriented NNE-SSW..."
