Abstract
The Gryde Local Fauna, Frenchman Formation (Maastrichtian: Lancian) of southwestern Saskatchewan, contains 19 mammalian species, including new species Parectypodus foxi, Alphadon jasoni, and Turgidodon petiminis. The assemblage occurs in fine-grained siltstones deriving from floodplain depositional environments. The Gryde Local Fauna preserves a relatively unaltered record of a floodplain mammalian community that lived in homogeneous habitats. Turgidodon petiminis and Mesodma hensleighi may have been restricted to the floodplain, or nearly so. Species diversity, and standard indicators of diversity, were low but probably typical of late Cretaceous mammalian communities.
