Megafaunal Zones in the Alberta Mississippian and Permian
Seventeen faunal zones are discriminated and named from the more than 4,000 feet of strata lying between what is conventionally regarded as the top of the Devonian and the base of the Mesozoic in Alberta. Of these zones, two are of Permian age, fourteen are Mississippian, and the earliest is either Mississippian or Devonian.
Within the Mississippian, the Spirifer leidyi, Spirifer increbescens, and Dictyoclostus inflatus zones fall within the Chesterian ; faunas from the Faberophyllum leathamense zone down through the Ekvasophyllum inclinatum zone are Meramecian; those from the Spirifer keokuk through the Camarotechia cobblestonensis zone Osagean, and the remainder, with the possible exception of Zone 1, are Kinderhookian.
Zones from the second through the sixth from the base are grouped in the proposed Banff Series, and the remaining Mississippian zones in the Rundle Series, corresponding to the Banff formation and Rundle group at the type locality, Mount Rundle, Banff, Alberta, respectively.
Figures & Tables
As a result of the intensive search for oil and gas in western Canada, a regional meeting was held in 1955. This volume was the result of that meeting, and contains 23 papers divided between a discussion of the Jurassic and a discussion of the Carboniferous. Stratigraphy, subsurface, boundaries, formations, sedimentation and geology of western Canada and adjacent areas are thoroughly covered.
