Lower Cretaceous flora from Byers Peninsula, South Shetland islands, Antarctica

New paleofloristic findings on Byers Peninsula, Shetland Islands, Antarctica, expand our knowledge about Mesozoic floras from that continent. Twenty-seven taxa of hepatophytes, equisetaleans, ferns, pteridosperms, bennettitaleans, pentoxylaleans and conifers are described. The first occurrence of he...
