Abstract: Mentioned is a brief history of the studies on the petrified woods from the Cretaceous and Tertiary of Antarctica and Patagonia. Among nine fossil species described from Antarctica so far, seven were recog-nized to occur also in Patagonia. It is suggested that the species from Patagonia are expected to be found from Antarctica in the near future. Four species of petrified woods including two new species were described from the Tertiary of Chilean Patagonia. 1
