Where: Greenland (74.1° N, 23.0° W: paleocoordinates 30.8° S, 48.9° 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 the basal part of the Ella Island Fm (see fig. 1), adjacent to GGU 314811 and GGU 314813, immediately below GGU 314814, and immediately abvove 314810. 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 strata collection is derived from must be less than 2m, and lies within a 80-100 m thick section.
• bed-level stratigraphic resolution
Environment/lithology: shallow subtidal; lithified limestone
Size class: macrofossils
Preservation: cast, mold/impression, original calcite, original phosphate, replaced with phosphate
Collection methods: bulk, chemical, acetic, sieve,
• COLLECTOR: Collected by S. Peel and M.P. Smith (1988), and earlier collectors. PREPARATION: 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. REPOSITORY: All specimens are housed in the Geological Museum in Copenhagen (MGUH).
