Also known as Loc. 18, Sekwi Brook South, Blueflower Fm., Canada - Narbonne and Aitken 1990

Where: Northwest Territories, Canada (64.7° N, 132.0° W: paleocoordinates 48.1° S, 82.5° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Avalon other zone, Lower Member (Blueflower Formation), Ediacaran (635.0 - 541.0 Ma)

• The terminal Windermer Formations make up four, kilometer-scale, shallowing-upward, carbonate capped Grand Cycles. The Gametrail, Sheepbed, Blueflower, and Risky Formations art thought to be equivalent to the the Redkino "Series" of Vendian Age on the Russian Platform. = Basal member of Pyle et al. (2004) and Lower member of Rooney et al (2020). Radiometric date from base of member/formation.

• bed-level stratigraphic resolution

Environment/lithology: offshore; lithified shale and sandstone

Size class: macrofossils

Preservation: cast, mold/impression, trace

Collection methods: bulk,

• Float that could not be tied down definitely stratigraphically was not included in the study material. Ediacaran body fossils occur predominantly as raised features on the bottom of beds and very rarely as depressed features on soles. The Sekwi Brook fauna represent the first Ediacaran assemblage on a slope setting/
