Upper Visby Beds: Fossils of reef limestone (Manten 1971, Table IX) (Silurian of Sweden)

Also known as Reef 3671

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 Formation, Sheinwoodian (433.4 - 430.5 Ma)

• Correlation based on Jeppsson (1983), Fossils and Strata 15:128.

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; limestone and reef rocks

• "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."

Size classes: macrofossils, mesofossils
