NEW GINKGOPHYTES FROM THE UPPER TRIASSIC–LOWER CRETACEOUS OF SPITSBERGEN AND EDGEØYA (SVALBARD, ARCTIC NORWAY):THE HISTORY OF GINKGOALES ON SVALBARD
Premise of research. During the ongoing investigation of Upper Triassic–Lower Cretaceous plant macrofossilsfrom Svalbard, Norway, some ginkgoalean leaf fossils were found from Carnian and Aptian deposits ofSpitsbergen and Edgeøya that represent newginkgophyte species. One newspecies is described...
