Where: Gotland, Sweden (57.5° N, 18.4° E)

• Paleocoordinates: 4.1° S, 47.5° W (Wright 2013)

• coordinate based on political unit

• local area-level geographic resolution

When: lower part Member (Mulde Formation), Homerian (430.6 - 426.7 Ma)

• 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."
