Hogklint Bed a Tentaculitids (Silurian of Sweden)

Where: Gotland, Sweden (57.5° N, 18.4° E: paleocoordinates 21.6° S, 2.9° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Unit A Member (Hogklint Formation), Sheinwoodian (433.4 - 430.5 Ma)

• Correlation from Jeppsson (1983), Fossils and Strata 15:128

• bed-level stratigraphic resolution

Environment/lithology: open shallow subtidal; marl and limestone

• SEP: from Samtleben et al. Geol Rundsch 1996. 85:278; "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." based on ref 6127 almost all of these samples come from the marls

Size class: macrofossils
