Fossils of Spangande Limestone at Stora Karlso (Silurian of Sweden)

Where: Gotland, Sweden (57.6° N, 18.3° E)

• Paleocoordinates: 8.7° S, 49.6° W (Wright 2013)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Spangande Limestone Formation, Sheinwoodian (433.4 - 430.5 Ma)

• Manten believes this unit to correlate with Slite IV beds on Gotland.

• group of beds-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, gray, blue limestone

• SEP environmental call based on given info.

• ...stratified crystalline limestone, surrounding the major reefs of the island and consequently very fossiliferous...The colour of the rock is generally bluish grey to red-mottled. The some extent there is a direct relationship between the thickness of the layers and the purity of the limestone of which they consist. (Manten 1971, p. 230)
