Mulde Beds Brachiopods (Silurian of Sweden)
Where: Gotland, Sweden (57.2° N, 18.4° E: paleocoordinates 20.1° S, 2.5° W)
• coordinate based on political unit
• local area-level geographic resolution
When: Mulde Beds Formation, Homerian (430.5 - 427.4 Ma)
• Correlation from Jeppsson (1983), Fossils and Strata 15:128
• group of beds-level stratigraphic resolution
Environment/lithology: offshore; argillaceous lime mudstone 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; "....series of argillaceous and micritic limestones and marls with a diverse marine fauna but impoverished conodont assemblage deposited in a shelf basin under calm conditions well below wave base."
