The rise of flowering plants in the high southern latitudes of Australia

Abstract

The Early Cretaceous high-paleolatitude palynofloras from the Otway and Gippsland basins of southeastern Australia contain diverse angiosperm assemblages not described previously. Clavatipollenites hughesii recovered from the early Aptian Upper Cyclosporites hughesii subzone in the Gippsland Basin represents the first record of angiosperm pollen in Australia, coeval to records recovered from the Great Artesian and North West Shelf basins of northern Australia. Tricolpate pollen including Tricolpites variabilis, Rousea georgensis and Striatopollis spp., are first recorded in the late Albian Upper Coptospora paradoxa subzone in southeastern Australia. This represents the second oldest occurren..
