Where: Greenland (74.4° N, 22.8° W)
• Paleocoordinates: 17.6° N, 84.6° W (Wright 2013)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Bastion Formation, Dyeran (515.3 - 509.7 Ma)
• SPECIFIC COMMENTS: Collection is from near the base of the Bastion Formation. Lumped collections from same horizon, including GGU 314901-10, 31, 33-34.
•
•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.
• bed-level stratigraphic resolution
Environment/lithology: marine; shale
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)
