Miocene algae and spores from tierra del fuego, Argentina

Continental deposits of the Cullen Formation (early or middle Miocene) exposed on the northeast coast of Isla Grande de Tierra del Fuego (southernmost Patagonia) are analyzed. Twenty-four taxa of algae, and bryophyte and pteridophyte spores are identified, including three new species, which are Anth...
