GGU 314836 - Albert Heim Bjerge (Cambrian of Greenland)

Where: Greenland (74.1° N, 23.0° W: paleocoordinates 30.8° S, 48.9° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Bastion Formation, Dyeran (516.0 - 513.0 Ma)

• SPECIFIC COMMENTS: Collection is from the base of the upper (shale) part of the Bastion Formation.

•GENERAL COMMENTS: The Kloftelv Formation is overlain by the fossiliferous Bastion and Ella Island foramtions, both of middle Dyerian age (late Early Camrbian, equivalent of the Botomian). The Bastion Formation is 150 m thick at Athe Albert Heim Bjerge locality is mainly galuconite-rich sandstone and siltstone in the lower part and shale with minor carbonate in its upper part.

• bed-level stratigraphic resolution

Environment/lithology: marine; shale

• The Bastion and Ella Island Formations from part of a thick succession of shallow-marine Proterozoic-Ordovician sediments deposited on the Laurentian shelf.
• Shale with minor carbonate.

Size class: macrofossils

Collection methods: bulk, chemical, acetic, sieve,

• Rock samples were dissolve in buffered 10 percent acetic acid to retrieve acid-resistent microfossils. The resulting residues were sieved and the heavy mineral fraction separated using sodium polytungstate. All specimens are housed in the Geological Museum in Copenhagen (MGUH)

Taxonomic list

• Exhaustive for Brachiopoda. The residues of the acid-digested samples contain a well-preserved and diverse small shelly fauna including helcionellid molluscs, coelosclerites, lapworthellids, and problematic fossils.
