The first fossil mammal from the Hudson Bay Lowland of Manitoba, a molar from the woolly or Siberian mammoth, Mammuthus primigenius, is described from near Bird. A lophar index of 9.0 and an enamel thickness of 1.5–2.3 mm allow the tooth to be assigned to an early form of the species. Although in situ provenance of the molar is unknown, it is likely that the molar derives from Early Wisconsinan or Sangamon sediments that outcrop in the area. A boreal steppe or steppe–tundra environment is indicated by the presence of woolly mammoth, supporting a depositional environment north of the then tree line previously established for the Nelson River sediments.
