Where: Northwest Territories, Canada (64.7° N, 132.0° W: paleocoordinates 32.6° S, 76.0° W)
• coordinate based on political unit
• outcrop-level geographic resolution
When: Sheepbed Formation, Wonokan to Wonokan (580.0 - 580.0 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.
• formation-level stratigraphic resolution
Environment/lithology: submarine fan; lithified siltstone and sandstone
Preservation: trace
Collection methods: 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/
