    The age of the upper McKay Group based on conodont biostratigraphy is latest Cambrian (Cordylodus proavus Zone) to late Early Ordovician (middle Floian; Oepikodus communis Zone).A collection of 12 conodont elements was recovered from samples of upper McKay Group strata exposed in the Western Main Ranges of the southern Canadian Rocky Mountains, southeastern British Columbia. The age of the upper McKay Group based on conodont biostratigraphy is latest Cambrian (Cordylodus proavus Zone) to late Early Ordovician (middle Floian; Oepikodus communis Zone).

The Survey Peak Formation is a stratigraphic unit of latest Cambrian to earliest Ordovician age. It is present on the western edge of the Western Canada Sedimentary Basin in the Canadian Rockies of Alberta and British Columbia.

It was named for Survey Peak near Mount Erasmus in Banff National Park by J.D. Aitken and B.S. Norford in The Survey Peak Formation is fossiliferous and includes Country: Canada. Outram Formation. Peyto Formation.

Abstract. Organic-walled microfossils from Wilcox Pass, in the southern Canadian Rocky Mountains, are described from 65I.9 m of mainly shallow water marine carbonate deposits belonging to the Survey Peak Formation, the Outram Formation, and the lowest 32 m of the Skoki Formation.

The formations are, in ascending order, the Survey Peak, Outram, Skoki, and Owen Creek (uppermost Cambrian through Darriwilian). The isotope analyses were undertaken also to check for possible effects of the pattern of Grand Cycles in the lithostratigraphic record and the possible relationship with periodic extinctions expressed by trilobite.

Ordovician Survey Peak, Outram, and Skoki formations of the southern Canadian Rocky Mountains. Several assemblages are recognized, and three new species of acritarch are described. The assemblages were dated mainly by using established trilobite zones as reference.
