摘要: Plant macrofossils can be used as proxy palaeoclimatic indicators, since both the taxa present at a site and form ofleaves depend on the climate, are rarely transported far. In simple case of Sirius Group Nothofagus leaves wood in Antarctica, the fossils provide data on climate that suggest temperatures time deposition were order of> 10°C warmer than present. While age is still debated, climatic signal not. However, more subtle cases, where differences smaller and fossil evidence complex, it critical to interpret cauriously. Macrofossils from Pleistocene localities in Tasmania clear temperature rainfall sometimes odds with pollen-based reconstructions, bur former is inherently likely accurate.
