Coarse fluvial deposits representing stream levee, point-bar and channel-fills are present, as are finer grained deposits of flood basin back-swamps (Hickey and Doyle, 1977).
Deposition usually in lacustrine or fluvial environments, whereas plants from deserts and very dry areas are unlikely to be fossilized to any extent.
In Australia, angiopollen is more common in terrestrial and marginal marine sediments (Dettmann, 1986).
