Nuculoid and Modiomorphid bivalves of the Burgsvik Beds (Silurian of Sweden)
Where: Gotland, Sweden (57.1° N, 18.3° E: paleocoordinates 14.3° S, 2.2° W)
• coordinate based on political unit
• local area-level geographic resolution
When: Burgsvik Beds Formation, Ludfordian (421.3 - 418.7 Ma)
• group of beds-level stratigraphic resolution
Environment/lithology: marine; sandstone and ooidal limestone
• Ref. 11073: "Burgsvik Beds (47m): Predominantly crossbedded and well-sorted sandstones with small-scale oscillation ripplemarks, load castings and ichnocoenosis indicate origin in a foreshore area. The uppermost part of this series consists of thinly crossbedded oolitic limestones, which indicates a trend toward more marine conditions."
