The late Middle Jurassic to early Late Cretaceous non-marine and marine sediments in the Great Australian Bight region were deposited during initial rifting between Australia and Antarctica. These sediments have been drilled and logged in Echidna-1 and Platypus-1 in the Duntroon Embayment. Potoroo-1 on the northernmost margin of the Great Australian Bight Basin, and Jerboa-1 in the Eyre Sub-basin. In these logged wells is recorded a conformable sequence through the Murospora florida, Retitriletes watherooensis, Cicatricosisporites australiensis, Foraminisporis wonthaggiensis and Cyclosporites hughesii spore-pollen Zones. The Coptospora paradoxa spore-pollen Zone is present in Platypus-1 and Potoroo-1, and three wells(Jerboa-1, Platypus-1, Potoroo-1) include the Phimopollenites pannosus and Appendicisporites distocarinatus spore-pollen Zones. In these three zones, dinoflagellates represent the Canninginopsis denticulata, Pseudoceratium ludbrookiae and Diconodinium multispinum Zones. The palynological zonation ...
