New palynological analysis of the Middle Eocene to Middle Miocene Latrobe Group coals of the Gippsland Basin in Australia sheds new light on fire adaptation in Australia's modern flora. The distribution of charcoal and fire-prone flora within brown coals is entirely controlled by facies and the paleoenvironments within the peatland, and does not result from drier climates as has been previously suggested. There is therefore, no evidence of climatic drying from this Cenozoic peatland record. Charcoal and fire-prone floras are associated with emergent and meadow marsh environments that produce darker coal lithotypes. Counter-intuitively, the low-nutrient and fire-prone environments that fringe..View full abstract
