PALAEOECOLOGICAL EVALUATION For a palaeoecological evaluation of the Iharosberény assemblage, the upper flora originating from a depth of 23.5-607.0 m and the lower flora from between 1646.0-1779.1 m must be separated. The lower flora differs significantly from the upper one both in species composition and ecological indications. Most of the species encountered here are members of the subtropical laurel forests, i.e. one can justly suppose that they formed a zonal vegetation. Palaeocarya orsbergensis and Platanus neptuni constituted the foliage level of the subtropical laureate forest while the species of Daphnogene and Laurophyllum dominated the shrub layer and the lower foliage layer. The zonal subtropical forest was bordered by groves leading towards a riparian, flood plain environment documented by Acer tricuspidatum, Myrica banksiaefolia, Zelkova zelkovaefolia and Ulmus pyramidalis (Text-fig. 4). The members of the upper flora originate from a uniform swamp en­Text-fig. 4 - Reconstruction of the Early Miocene flora of Iharosberény. Pn = Platanus neptuni; Pyo = Paleocarya orsbergensis; Ts = Tetraclinis salicornioides; D = Daphnogene div. sp.; Z = Zelkova zelkovaefolia; C = Cassia sp.; L = Laurophyllum sp.; At = Acer tricuspidatum; U = Ulmus sp.; Up = Ulmus pyramidalis; My = Myrica banksiaefolia vironment. All species present existed in a biotope determined by edaphic factors. In the swamp vegetation, the most common arboreal species are Gfyptostrobus eu­ropaeus and Alnus cecropiaefolia, accompanied by Ulmus sp., Salix sp., and other species of Alnus. The shrub layer was occupied by Byttnerophyllum tiliaefolium and Text-fig. 5 - Reconstruction of the Pannonian flora of Iharosberény U sa Ulmus sp.; Gy = Gfyptostrobus europaeus; Al = Alnus cecropiaefolia; By = Byttneriophyllum tiliaefolium; Os = Osmunda parschlugiana; Sx = Salix sp.
