Kappelshamn (Silurian of Sweden)

Where: Gotland, Sweden (57.9° N, 18.8° E: paleocoordinates 21.3° S, 2.8° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Ozarkodina sagitta rhenana conodont zone, Tofta Formation, Sheinwoodian (433.4 - 430.5 Ma)

• formation-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; oncoidal limestone and reef rocks

• SEP: Silurian of Gotland has been variably described as a ramp and platform. Based on my read of the literature, I think if falls best into the ramp category. From Samtleben et al. (1996). Geol. Rundsch 85:278-292; "Predominant in this unit are oncolitic limestones and biostromal carbonate buildups which were formed by algae and a few stromatopore species. A monotonous benthic association comprised only of a few species indicates restricted marine, somewhat lagoonal conditions. Mud cracks are evidence of episodic emersion and desiccation."

Size class: macrofossils

Reposited in the SM
