Where: Greenland (74.4° N, 22.8° W: paleocoordinates 30.5° S, 48.8° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Ella Island Formation, Dyeran (515.3 - 511.2 Ma)
• STRATIGRAPHIC RELATIONS: From Ella Island Fm, which overlies the Bastion Fm and in turn the Kløftelv Fm (lower Cambrian) and is overlain by the Hyolithus Creek Fm (lower-middle Cambrian) and Dolomite Point Fm (middle Cambrian). STRATIGRAPHIC POSITION: From near top Ella Island Fm; correlative to GGU 313915. AGE: Well constrained to the late Early Cambrian (Dyeran Age or Bonnia-Olenellus Chron; see Palmer 1998) by the presence of Olenellid trilobites (Poulson 1932, Cowie and Adams 1957) and baltisphaerid acritarchs (Vidal 1979). THICKNESS: Thickness of formation at the Albert Heim section is 80-100 m.
• bed-level stratigraphic resolution
Environment/lithology: shallow subtidal; lithified 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)
