A late Oligocene (Egerian) flora from Környe, near Tatabánya, N Hungary

In the course of the groundworks of the 'Kornye Industrial Park' near Tatabanya (N Hungary), fossiliferous beds of the Oligocene Many Formation were exposed. Sediments comprised abundant plant remains with typical Oligocene species, such as "Rhamnus" warthae, Alnus oligocaenica accompanied by elements thriving in humid habitats, e.g. the fern Pronephrium stiriacum in large quantities, and the conifer Glyptostrobus europaeus. The majority of angiosperms, such as Mastixia amygdalaeformis vel Nyssa sp., Quercus rhenana and two predominant taxa, "Rhamnus" warthae and Alnus oligocaenica, which are characteristic of Egerian floras, indicate wetland environment. The floristic composition suggests intrazonal, edaphic vegetation.
