GGU 314835 - 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 limestone unit, stratigraphically midway up the Bastion Formation. Same stratigraphic height as GGU 314805-7

•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: limestone

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

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. Add Gubanov et al. press and Skovsted in press (at the time of April, 2005) for complete fauna - references in current reference.
