MUSOPSIS N. GEN.: A BANANA‐LIKE LEAF GENUS FROM THE EARLY TERTIARY OF EASTERN NORTH GREENLAND
A fossil flora from the Late Paleocene‐Early Eocene Thyra Ø Formation of eastern North Greenland (paleolatitude 77° N) has yielded monocotyledon leaf impressions with characters seen only in the closely related modem species in the families of Heliconiaceae, Musaceae, and Strelitziaceae. The combina...
