Seed plant diversity in the Triassic of Antarctica: A new anatomically preserved ovule from the Fremouw Formation
International audience A new anatomically preserved ovule is described from the Middle Triassic Fremouw Formation of the Beardmore Glacier area, Antarctica. Probolosperma antarcticum gen. et sp. nov. is bilaterally symmetrical and up to 1 cm long and 6 mm wide. The integument is characterized by a c...
