Upper Devonian Plant Microfossils from Eastern and Arctic Canada: Their Taxonomy and Palaeoecological Significance
Plant microfossils are extracted from strata of Upper Devonian age occurring at two previously uninvestigated localities in Eastern Canada and in the Canadian Arctic. The extraction procedure includes a new permanent palynological mounting technique using corn syrup and Permount, a synthetic resin....
