Hogklint Beds: Fossils of Hoburgen-type reef limestone (Manten 1971, Table IX) (Silurian of Sweden)

Also known as Reef 1799

Where: Gotland, Sweden (57.5° N, 18.4° E: paleocoordinates 18.4° S, 2.5° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Hogklint Beds Group, Sheinwoodian (428.2 - 426.2 Ma)

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

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; shelly/skeletal grainstone and reef rocks

• Ref. 11073: "Well-sorted biodetritic and crinoidal limestones (grainstones and packstones), often cross-bedded, contain irregularly arranged massive bioherms, which were built up predominately by stromatopores...coarse biodetritic limestones in the vicinity of these reefs grade into inter-reef sediments consisting of limestone-marl alterations."
