  • Original language description

    A new fossil eusporangiate fern Marattiopsis vodrazkae J. Kvaček, sp. nov. has been recovered from the Hidden Lake Formation, the Campanian of James Ross Island, Antarctica. Its fertile and sterile pinnules are described and compared to the other speciesof the fossil genus Marattiopsis Schimper and the living genera Marattia, Ptisana and Eupodium (Marattiaceae). In contrast to the other species of the genus Marattiopsis, M. vodrazkaeis characterised by stalked synangia, a smaller number of sporangia per synangium, generally small sized pinnules, and the absence of venuli recurrentes. It shows a mosaic of characters present in the living Marattiaceae: it shares stalked sporangia with the genus Eupodiumand some species of Marattiaand exhibits a suture (an abscission scar at pinnule bases), a character typical for the genus Ptisana. Additionally, M. vodrazkae provides important palaeoenvironmental signals for climate reconstructions, arguing for warm (paratropical to warm-temperate) and
