78 Egerian plant fossils from Vértesszőlős, NW Hungary By L. HABLY (Received September 30, 1986) Abstract: A taxonomic analysis, palaeofloristical and palaeoclimatological reconstruction of a Hungarian Egerian flora is presented. With 143 figures and 40 plates. INTRODUCTION During the construction of the road Ml crossing the NW parts of Hungary in 1972, the workers observed leaf prints when scraping away a hill named Baromállas between Tatabánya and Vértesszőlős. They informed dr. István SKOFLEK, collaborator of the Kuny Domonkos Museum (Tata), who collected the plant remains with the help of his students. SKOFLEK published a list on the new palaeofloristical sites of Komárom county including the locality among the relics of Oligocène flora in 1974. The material published here was given to the author for scientific elaboration by SKOFLEK. Following the first collections, further samples were obtained from the left-overs of the locality. The material is deposited in the collection of the Kuny Domonkos Museum (Tata). Among the Upper Oligocène floristical assemblages published from Hungary, only the floristical assemblage of Eger - Wind's Brickyard (ANDREÁNSZKY 1966b, NAGY and PÁLFALVY 1963) as well as a minor assemblage of Csörög environs is mentioned (VITÁLIS and ZILAHY 1952). PÁLFALVY (1967) published a floristical list from Kesztölc dated Upper Oligocène, without description and illustrations. HABLY published floristical assemblages of this period from Verőcemaros (1982), Kesztölc (1988) and Nagysáp (1989). The localities of Eger, Csörög, Verőcemaros are located on the northern parts of Hungary, on the territory of the Egerian and Kovacov Formations. Personal communications of the last few years informed us on several more Upper Oligocène outcrops found in course of geological surveys. Taking all these into consideration, still we must emphatically stress the importance of the Vértesszólős flora, both in respect of its richness and its geographical position. Situated at the westernmost part of the formations of the Egerian stage, the section yielded information on another Egerian formation, the Many formation and its vegetation

. On some fintis of the Vértesszőlős flora, there are only some brief publications available as yet (HABLY 1976, 1979a, AMBRUS and HABLY 1979, HABLY and CSABA 1977). The complete description of the material as well as the evaluation of the flora has been performed recently, during which several new results were achieved enriching our knowledge on the Hungarian Upper Oligocène flora.
