Burgsvik (Silurian of Sweden)

Also known as Burgsvik Beds Brachiopods

Where: Gotland, Sweden (57.0° N, 18.3° E: paleocoordinates 16.9° S, 2.2° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Ozarkodina snajdri conodont zone, Burgsvik Beds Formation, Ludfordian (425.6 - 423.0 Ma)

• Correlation from Jeppsson (1983), Fossils and Strata 15:128. Also in Monograptus balticus graptolite zone (PJW3; Calner 2005 Facies (2005) 51: 584–591 DOI 10.1007/s10347-005-0050-0).

• 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."

Size class: macrofossils
