ABSTRACT
The Late Cretaceous flora of the Klikov Formation (Upper Turonian-Santonian) in South Bohemia comprises 110 species representing pteridophytes, ferns, conifers, angiosperms, macro and mesofossils. Palaeoclimatic analysis of the Klikov Formation Flora using methods of Leaf Margin Analysis, Climate Leaf Analysis Multivariate Program (CLAMP) and the Nearest Living Relative allows us to conclude that this flora experienced a seasonally dry subtropical climate. Mean annual temperature is predicted to have been approximately 15°C. Numerous charcoalified fossils strongly suggest frequent fires typical of a seasonally dry climate.
