Preliminary paleopalynology of the Kanguk Formation (Upper Cretaceous), Remus Creek, Canadian Arctic Archipelago: I. Marine Palynomorphs
A 39 m section of the Kanguk Formation (Upper Turonian to Lower Campanian) on Remus Creek, Ellesmere Island, was sampled at about one inetre intervals to provide stratigraphic control on palynomorph taxa present. These samples yield well-preserved marine and terrestrial palynofloras represented by a...
