Eurypterid-Associated Biota of the Sundvollen Form. at Rudstangen, Oslo Region (Silurian of Norway)

Where: Norway (59.9° N, 10.8° E: paleocoordinates 16.9° S, 7.3° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Sundvollen Formation, Rootsikula (426.2 - 422.9 Ma)

• "Sundvollen Formation. Late Wenlockian."

• formation-level stratigraphic resolution

Environment/lithology: fluvial; gray siltstone and sandstone

• "Turner (1974) interprets the Sundvollen Formation as representing meandering, braided streams on an alluvial, coastal plain, very close to sea level (minor marine incursions found). Indicated by Boucot and Janis (1983) to be possibly brackish-estuarine."
• "Dark-gray siltstone associated with red sandstone and siltstone, with ripple marks, cross-laminations, and crack diapirs, and pseudo-nodules; carbonate concretions; fining upwards 'cyclothems'; tracks attributed to eurypterids have been found in the red siltstone."

Size class: macrofossils
