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 (515.3 - 511.2 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
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)
