Oncocerid cephalopods of Slite Beds at Norrvange kanal (Silurian of Sweden)
Where: Gotland, Sweden (57.6° N, 18.3° E: paleocoordinates 21.6° S, 3.0° W)
• coordinate based on political unit
• local area-level geographic resolution
When: Slite Beds Formation, Sheinwoodian (433.4 - 430.5 Ma)
• group of beds-level stratigraphic resolution
Environment/lithology: deep subtidal ramp; limestone and marl
• 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 deeper facies.
