Australia: The Land Where Time Began

A biography of the Australian continent 

Pollen Core Lynchs Crater, Atherton Tablelands - The moist tropics

This is a small volcanic lakeon the Atherton Tableland of northeastern Queensland. Until about n78,000 BP there were rainforest conifers, mostly Araucaria and Podocarpus that increased during cooler, drier periods, while in the interglacials angiosperms predominated (Kershaw, 1986; Moss & Kershaw, 2000). Sclerophyll forests of mixed eucalypt and acacia replaced the rainforests at about 46,000 BP, the speed of change increasing between 40,000 and 35,000 BP (Turney et al., 2001). Immediately prior to the LGM there was an increase in Poaceae,, indicating increasing swamp grass as the water level of the lake dropped. The Poaceae declined at the LGM, indicating the lake may have dried completely. Prior to 46,000 BP charcoal was practically absent from the record, but there was a sharp rise of charcoal at 46,000 BP (Turney et al., 2001).
