Also known as Was: GSC locality 92316, Skoki Fm., Biozone J, Alberta, Canada - Dean 1989

Where: Alberta, Canada (52.9° N, 118.1° W: paleocoordinates 1.2° S, 69.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: J trilobite zone, Sikanni Chief Member (Skoki Formation), Blackhillsian (474.9 - 470.0 Ma)

• The deposits comprise detrital belts near the margin of Laurentia. Part of the Ordovician Ibex Series.

•

•Was Tremadoc, but J is Blackhillsian (PJW). Also, the conodont zones for Sikanni Chief (Jumudontus gananda and Tripodus laevis) both are younger than Zone J (Pseudocybele nasuta) according to Pyle & Barnes (2003). So, is this really Outram?

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified, sandy dolomite

Size classes: macrofossils, mesofossils

Reposited in the GSC

• Brachiopods are mentioned to occur in the formation, but their placement and lower taxa names are not given. An index of A to M is used to designate Ordovician biozones (Ross, 1949, 1951a, p.27-29) for the Wilcox Pass Area.
