Geography
Country:Greenland
Coordinates: 74.1° North, 23.0° West (view map)
Paleocoordinates:30.8° South, 48.9° West
Basis of coordinate:estimated from map
Geographic resolution:outcrop
Time
Period:Cambrian Epoch:Early/Lower Cambrian
10 m.y. bin:Cambrian 2
Key time interval:Dyeran
Age range of interval:516.00000 - 513.00000 m.y. ago
Stratigraphy
Formation:Bastion
Stratigraphic resolution:bed
Stratigraphy comments: 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.
Lithology and environment
Primary lithology: "shale"
Includes fossils?Y
Lithology description: Shale with minor carbonate.
Environment:marine indet.
Geology comments: The Bastion and Ella Island Formations from part of a thick succession of shallow-marine Proterozoic-Ordovician sediments deposited on the Laurentian shelf.
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Collection excludes:some macrofossils
Collection methods:bulk,chemical,acetic,sieve,field collection,survey of museum collection
Reason for describing collection:taxonomic analysis
Collection method comments: 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 comments: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.
