The study involved palynological analyses of samples from two wells on the Exmouth Plateau to determine Late Triassic vegetation. Stratigraphic units were identified and correlated using bioevents against the regional chronostratigraphy. The Mungaroo and Brigadier formation sediments were deposited in environments from Norian to Rhaetian, upper to lower delta plain, coastal, and marine settings, and were assigned to the M. crenulatus and A. reducta spore-pollen zones. The characterization of botanical affinities of palynomorphs allowed to reconstruct the paleofloral dynamics during the interval considered. Accordingly, climate demonstrated a shift towards warmer, wetter conditions at the end of the Triassic.
