Abstract
A new fossil mammal fauna from Canada is described. The locality, called Who Nose?, occurs in strata pertaining to the Paskapoo Formation, exposed on Nose Creek in northeast Calgary, Alberta. A sedimentological profile suggests deposition was fluviodeltaic in origin, and likely occurred in a channel-fill/oxbow complex. To date, some 400 dental specimens representing nine mammalian orders have been recovered, among them numerous well-preserved jaws. Biostratigraphic correlation suggests a latest Torrejonian age for the fauna based on the presence of the index taxon 'Pronothodectes matthewi'. Faunal compositional analysis indicates a close similarity to the penecontemporaneous Gidley Quarry fauna of Montana. Recent magnetopalynostratigraphic analyses of strata containing the Who Nose? locality resulted in correlation with magnetic anomaly 28r, which correlates instead with early Torrejonian faunas in the Western Interior of the United States. The implied homotaxial diachroneity is here considered improbable, with local geological phenomena likely accounting for the discordant faunal correlation.
