Paulinitid polychaetes of the Upper Visby Beds (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: Upper Visby Beds Formation, Sheinwoodian (433.4 - 430.5 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: deep subtidal ramp; packstone and lime mudstone

• 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 series of micritic limestones and marls (of the Lower Visby) shows upward increasing intercalations of biodetritic limestones (packstones, in the upper part grainstones) which indicate episodes of wave-base influence on the sea floor...erosional discordances and channel structures indicate the effects of bottom currents."
