Palynological evidence for aridity events and vegetation change during the Middle Pliocene, a warm period in Southwestern Australia

Dodson, John Richard; Macphail, Michael


A 110-m-thick sequence of Late Neogene lacustrine silts and clays is sealed under Quaternary cover beds in a Cretaceous meteor crater at Yallalie in semiarid to subhumid southwest Western Australia. Paleomagnetic dating confirms that these sediments accumulated between 3.6 and ∼2.5 Ma. This Middle Pliocene (Piacenzian) interval coincides with a period of pronounced global warming recorded at middle to high latitudes in both hemispheres and plant microfossils preserved at Yallalie include...[Show more]
