..., and as thick as 200 m, and dwarf all previously described examples. Superimposed on the distal margin of an underlying Paleocene to mid-Eocene siliciclastic delta complex, the reef mounds provide a critical insight into changing paleoenvironments of the Australo-Antarctic Gulf ca. 43 Ma, coinciding with global...

... 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 of that isthmus. The Lowana Road...
