Hemse Beds Brachiopods (Silurian to of Sweden)
Where: Gotland, Sweden (57.2° N, 18.4° E: paleocoordinates 17.4° S, 2.3° W)
• coordinate based on political unit
• local area-level geographic resolution
When: Hemse Beds Formation, Gorstian to Gorstian (427.4 - 423.0 Ma)
• Correlation from Jeppsson (1983), Fossils and Strata 15:128
• group of beds-level stratigraphic resolution
Environment/lithology: carbonate
• SEP: based on this reference, it is impossible to tell which of the three principal environments (deep subtidal, biohermal/open shallow subtidal, or restricted shallow subtidal) represented by the Hemsa beds are the source of data. It is likely to be all three.
