Abstract

Detailed "Quaternary-style" quantitative spore-pollen counts, with a pollen sum based on total non-angiosperm seed plants, from a southern high palaeolatitude (60-65°) 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 ..
