Where: Spitsbergen, Norway (79.8° N, 17.8° E: paleocoordinates 79.8° N, 17.8° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Pseudocybele nasuta trilobite zone, Olenidsletta Member (Valhallfonna Formation), Billingen (474.8 - 471.1 Ma)
• While collections were made throughout section, only ranges of trilobite species are reported. Zone V2a comprises meters 75-100 of the Olenidsletta Member. Likely correlates with part of "zone J" of Ross 1951, Hintze 1951, 1952.
•
•This would be Billingen on the Baltic scale (PJW).
• group of beds-level stratigraphic resolution
Environment/lithology: slope; lithified, gray limestone and lithified, black limestone
Size class: macrofossils
