Slite Beds Brachiopods (Silurian of Sweden)

Where: Gotland, Sweden (57.7° N, 18.8° E)

• Paleocoordinates: 8.4° S, 49.5° W (Wright 2013)

• coordinate based on political unit

• local area-level geographic resolution

When: Slite Beds Formation, Sheinwoodian (432.9 - 430.6 Ma)

• Correlation from Jeppsson (1983), Fossils and Strata 15:128

• group of beds-level stratigraphic resolution

Environment/lithology: open shallow subtidal; peloidal, shelly/skeletal 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; "...this unit consists of a carbonate platform with reef mounds and surrounding shoal sediments of mostly pure biodetritic and pleoidal limestones. Here slow and discontinuous accumulation of carbonate material continued in a very shallow water but under normal marine conditions....to the south and southwest the carbonate platform passes with a conspicuous slope into a deeper shelf basin where a uniform alternation of micritic limestones and marls accumulated."

•Based on information provided in this collection, it is difficult to tell which facies is represented but I have assumed that it represents the more extensive shallow subtidal facies.
