Sekwi Brook North, Mackenzie Mountains (Ediacaran of Canada)

Also known as Windermeria aitkeni, Blueflower Fm.., - Narbonne 1994

Where: Northwest Territories, Canada (63.4° N, 128.4° W: paleocoordinates 49.2° S, 85.1° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: White Sea other zone, Upper Member (Blueflower Formation), Ediacaran (635.0 - 541.0 Ma)

• Specimens are found from the upper and middle portions of the Windermere Supergroup. Megafossils range through more than 2.5 km of section, making this the thickest succession bearing Ediacara-type fossils known anywhere in the world and the only ones to yield sub-tillite Ediacara-type megafossils.

• bed-level stratigraphic resolution

Environment/lithology: offshore; lithified mudstone and sandstone

• dark mudstone with thin interbeds of very fine grained turbiditic sandstone and decameter-scale packets of ribbon-bedded carbonates. Sand beds may be calcitic-cemented.

Size classes: macrofossils, mesofossils

Preservation: cast, mold/impression
