National Herbarium of Victoria, Royal Botanic Gardens Melbourne, South Yarra, Victoria 3141, AustraliaAbstract:Detailed “Quaternary-style” quantitative spore-pollen counts, with a pollen sum based on total gymnosperms, from a southern high palaeolatitude (66°) terrestrial sequence in Gippsland, southeast Australia has revealed strong vegetation and climate variability during the Albian. This variability is more pronounced than previously suggested in global Early Cretaceous vegetation and climate reconstructions. The quantitative spore-pollen record shows drying throughout the Albian based on upward decreasing total ferns and variation in podocarp and total Alisporites/Vitreisporites pollen. This record suggests that although global climate during the Albian is considered to have been warm, stable and equable, regional factors such as water availability and continentality were the main drivers of this vegetation change.
