Eutherian Mammal from the Early Campanian (Late Cretaceous) of Alberta, Canada

Abstract

TEETH of North American mammals of early Campanian age were recently discovered in the Upper Milk River Formation, southern Alberta, Canada1, and now dental remains of Triconodonta2, Allotheria3, Metatheria, and Eutheria are known. The teeth are rare and occur with the fragmented skeletal parts of fishes, salamanders, turtles, champsosaurs, lizards, crocodiles, saurischians, and ornithischians, as in younger Cretaceous strata of the Western Interior4,5.
