A unique occurrence of Bergaueria in the Lower Cambrian Gog Group near Lake Louise, Alberta

Three ichnospecies of Bergaueria—B. perata, B. hemispherica, and B. radiata—are described from the Lower Cambrian Gog Group near Lake Louise, Alberta. Usually populations of Bergaueria are monospecific and this occurrence is unique. Since all three ichnospecies are found on a single slab, the criteria used for ichnospecies differentiation appear valid.
