The trilobites from the Upper Cambrian to Lower Ordovician Survey Peak, Outram and Skoki formations at Wilcox Pass, Alberta, comprehensively described in this report, belong to 48 genera. One new genus and six new species are described, and type material for seventeen previously described species from corresponding strata elsewhere in the Rockies is redescribed or re-illustrated. This report establishes a biostratigraphic framework for the Wilcox Pass sequence, from the highest part of the Upper Cambrian Trempealeau Series through the entire Lower Ordovician, based on trilobite zones.

This volume presents the proceedings of Symposium I "Stratigraphy" of the 30th International Geological Congress at Beijing. The proceedings aim to present a view of contemporary geology and should be of interest to researchers in the geological sciences.

This paper provides new data on the succession of acritarch assemblages, and some information on that of chitinozoans, in warm, mainly shallow, water, marine carbonate deposits of the Canadian cratonic realm. The work is based on the well-exposed, almost continuous, unfaulted section at Wilcox Pass, located about 2.5 km north of the Athabasca Glacier, between Banff and Jasper, in the southern Canadian Rocky Mountains.

This compilation is a synthesis of Ordovician-Triassic conodont research undertaken in the Canadian Cordillera during the past decade. The studies include an overview of the record in Western Canada; a review of the paleontology; and descriptions of conodonts from the Cordillera Road River group in northern Yukon Territory, from the eastern and northern Canadian cordillera, of the Palliser Formation in the Rocky Mountains, and from the Cache Creek Complex in south-central B.C.
