Cenozoic siliceous flagellates from the Fram Strait and the East Greenland Margin: Biostratigraphic and paleoceanographic results
More than 110 taxa of siliceous flagellates including silicoflagellates, ebridians, actiniscidians, and synuraceans are tabulated from Cenozoic sediments of Holes 908A and 913B. The assemblages investigated from Hole 908A, Fram Strait, are assigned to the upper Oligocene Cannopilus hemisphaericus Zo...
