Nowadays, notothenioids are the teleostean group that dominates marine Antarctic waters.However, during the Mesozoic a diverse ichthyofauna inhabited the sea that surrounded Antarctic. Wepresent the preliminary results of the last two Argentinian Antarctic field expedition to the LateJurassic of Antactic Peninsula (Longing Gape) and Cretaceous-Paleogene of Seymour (=Marambio)Island. The fish material recovered is extremely abundant and their further detailed study may providesignificant clues into the taxonomy and paleobiogeography of the mesozoic antactic ichthyofaunas.
