文摘

Two new palaeobotanical sites, Gérce and Pula from western Hungary, found in volcanic craters are characterized in terms of floristic composition, vegetation, and palaeoclimate. Radiometric dating of adjacent volcanic bodies indicates the age of the fossiliferous deposits near the Lower/Upper Pliocene boundary. Deciduous broad-leaved, woody plants prevail in both localities (Quercus, Ulmus, Zelkova, Acer, Salicaceae) and are associated with some rare exotic elements (Ginkgo, Torreya, Engelhardia, Eucommia, Sassafras) and Buxus. The climatic conditions inferred from the reconstructed vegetation indicate a Cf-type of climate with a mean annual temperature of 10-13°C and some dry periods during the year.
