... complex rifting that began in the latest Jurassic–earliest Cretaceous. Rifting initially formed the Australo-Antarctic Gulf, which in the Early Eocene was a narrow, shallow seaway blocked at its eastern end by an isthmus connecting Australia to East Antarctica at 65°–70°S. Tasmania is a remnant...
