The Battle Formation is a geologic formation of Late Cretaceous (Maastrichtian) age in the Western Canada Sedimentary Basin.[3] It is present throughout much of the central Alberta plains, where it is an important stratigraphic marker in the nonmarine Upper Cretaceous sequence.[4] It was formally named by G.M. Furnival in 1942[2] and given formation status by E.J.W. Irish in 1970.[5][6]
