GSC loc. 101537, Section C, Unit 1, Canada - Narbonne and Hofmann 1987 (Ediacaran to of Canada)

Where: Yukon, Canada (66.0° N, 134.2° W: paleocoordinates 32.1° S, 74.1° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Siltstone Unit 1 Formation, Wonokan to Wonokan (580.0 - 580.0 Ma)

• The fauna are located in beds that occur above the highest Varangian tillites and below the lowest fossiliferous deposits of the Cambrian. Strata described occur in equivalents to the Upper part of the Windermere Supergroup. NOTE: No formal stratigraphic names are given, so the accepted informal names are listed in the Formation data field. Macrofossils are found sporadically throughout the lower 2/3 of the unit, trace fossils occur in lower 1/3 and upper 1/3. No slabs contained BOTH macro and trace fossils.

• group of beds-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; lithified shale and sandstone

• Generalization for the formations: alternating carbonate and fine siliclastics with fossils only in the silicalstics. Recessive-weathering shale and siltstone with sporadic interbeds of quartzose sandstone and minor dolostone. The sandstone beds are thicker than those found in Unit 2 and are more continuous laterally. Fossils mostly occur as positive features on soles of the sandstone beds and only rarely as negative features on the tops of these beds

Preservation: trace

Reposited in the GSC

• The Goz Siltstone, Silstone Unit 2, and the lower 2/3 or Siltstone Unit 1 contain faunal assemblages similar to the Redkino 'Series" of the Vendian, Russian Platform.
