Geography
| Country: | Greenland |
| Coordinates: | 74.4° North, 22.8° West (view map) |
| Paleocoordinates: | 30.5° South, 48.8° West |
| Basis of coordinate: | estimated from map |
| Geographic resolution: | outcrop |
Time
| Period: | Cambrian | Epoch: | Series 2 |
| 10 m.y. bin: | Cambrian 2-3 | ||
| Key time interval: | Dyeran | ||
| Age range of interval: | 514.80000 - 511.00000 m.y. ago |
Stratigraphy
| Formation: | Bastion | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: SPECIFIC COMMENTS: Collection is from near the top of the Bastion Formation. Clumped collections from GGU 314918-19 & 314937
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 Ella Island Formation (100 m thick) is mainlyy limestone and calcareous sandstone and is overlain by essentially unfossiliferous dolomites of the Hyolithus Creek and Dolomite Point formations, spanning the rest of the Cambrian Period. | |||||
Lithology and environment
| Primary lithology: | "shale" |
| Includes fossils? | Y |
| Lithology description: Limestone and calcareous sandstone. | |
| 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. | |
