A review of past and recent research on Cretaceous silicoflagellates
Previous knowledge of Cretaceous silicoflagellates has come primarily from scattered Maastrichtian or late Campanian localities. Silicoflagellates from the earlier Upper Cretaceous have been observed from the southern shore of the Baltic Sea and eastern slope of the northern Ural Mountains, and Lowe...

Previous knowledge of Cretaceous silicoflagellates has come primarily from scattered Maastrichtian or late Campanian localities.
