Conodont biostratigraphy of the Codroy Group (Lower Carboniferous), southwestern Newfoundland, Canada
Four stratigraphically successive conodont assemblage zones have been recognized in the Lower Carboniferous Codroy Group of southwestern Newfoundland. The Diplognathodus Zone is confined to the basal Ship Cove Limestone, and to a highly fossiliferous correlative at Aguathuna. The overlying Taphrogna...
