Oncocerid cephalopods of Hamra Beds at Stockviks kanal (Silurian of Sweden)

Where: Gotland, Sweden (57.5° N, 18.4° E: paleocoordinates 16.5° S, 2.4° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Hemse Beds Formation, Ludfordian (425.6 - 423.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; limestone

• SEP: original source indicates limestone occurrences for almost all specimens...in the Hemse, this strongly suggests shallow subtidal, but it is possibly deeper subtidal
