| Abstract | The well-known Jurassic macrofloras from Hope Bay at the northernmost tip of the Antarctic Peninsula continue to yield new taxa. This paper reports on a new type of plant reproductive organ. The affinity of this organ remains unclear; it may be affiliated with the Schizaceae or Osmundaceae, but similarities to pollen organs of the Podocarpaceae are also discussed. Because the fossils differ from hitherto known Mesozoic fertile fronds and conifer pollen organs in some details, the new taxon, Spesia antarctica nov. gen. et sp. is proposed. |
