Where: Gotland, Sweden (57.7° N, 18.8° E: paleocoordinates 18.2° S, 2.5° W)
• coordinate based on political unit
• local area-level geographic resolution
When: Slite Beds Formation, Sheinwoodian (428.2 - 426.2 Ma)
• Correlation from Jeppsson (1983), Fossils and Strata 15:128.
• bed-level stratigraphic resolution
Environment/lithology: open shallow subtidal; limestone
• 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.
