Description :
While Greater Antarctica remained continental throughout Mesozoic time, the Antarctic Peninsula was partly covered by sea. Present data suggest that the break-up of Gondwana was initiated in the Middle to data Jurassic with the first significant lateral movements in the Early Cretaceous. During this period, the Antarctic Peninsula area occupied an important paleogeographical position, near the junction of major new seaways that were opening between South America and Africa, along the eastern coast of Africa, and between India and the Antarctic-Australasian block. The biogeographical affinities of ammonite faunas in the Antarctic Peninsula are briefly reviewed in the light of these changing paleogeographical conditions.
