Where: Yukon, Canada (64.7° N, 132.0° W: paleocoordinates 1.7° N, 64.8° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Rabbitkettle Formation, Menevian (504.5 - 499.5 Ma)

• The formation at section """"N"""" of Pratt (1992) is over 400m thick, but only the lower 200 m are of interest. No sedimentological differences can be discerned through the upper Marjuman - lower Steptoean interval.

• formation-level stratigraphic resolution

Environment/lithology: deep subtidal ramp; lithified, argillaceous, calcareous sandstone and lithified siltstone

Size class: macrofossils

Collection methods: surface (in situ),

• The collection contains fossils from the upper Marjuman. The stage boundary between the Marjuman and Steptoean seperates two biomeres and is one of the global mass extinction events.
