The Duchesnean Lac Pelletier Lower Fauna, Cypress Hills Formation, Saskatchewan, includes 15 isolated teeth that are referred to the Carnivora (Mammalia). The fauna includes Miocyon magnus n. sp., Daphoenus cf. D. demilo, Hesperocyon sp., and indeterminate taxa; no members of the Creodonta were identified. This is the latest record of Miocyon and the earliest record of Hesperocyon. The fauna is transitional between Uintan carnivoran faunas that were dominated by miacids and the establishment in the early Chadronian of the White River carnivoran chronofauna, and suggests that the transition, which was largely a Duchesnean event, was gradual.
