Palynostratigraphic reassessment of the Late Devonian of Bjørnøya, Svalbard
A comprehensive study of the Late Devonian palynostratigraphy of Bjørnøya, Svalbard Archipelago is presented.A total of 61 samples collected from 10 outcrops located along the eastern coast of the island were analyzed forpalynology yielding a mid- to latest Famennian age. A reassessment of the exist...
