Abstract
An incomplete lower jaw with teeth documents the presence of a new genus and species of placental mammal from the Upper Cretaceous (Lancian; late Maastrichtian) Frenchman Formation, Saskatchewan, Canada. This new mammal is characterized by highly compressed lower molars that decrease in size from m1 to m3 and superficially resemble the molars of Tertiary Mesonychia. These resemblances, however, are interpreted as convergent, and the new mammal is classified in its own family and incertae sedis at the ordinal level. This new mammal thus joins other recent discoveries in western Canada of mammals of Tertiary aspect (Condylarthra; Taeniodonta) occurring in the Late Cretaceous.
