Abstract - Nowadays, notothenioids are the teleostean group that dominates marine Antarctic waters. However, during the Mesozoic a diverse ichthyofauna inhabited the sea that surrounded Antarctic. We present the preliminary results of the last two Argentinian Antarctic i eld expedition to the Late Jurassic of Antactic Peninsula (Longing Gape) and Cretaceous-Paleogene of Seymour (=Marambio)Island. The i sh material recovered is extremely abundant and their further detailed study may provide signii cant clues into the taxonomy and paleobiogeography of the mesozoic antactic ichthyofaunas.
