Bajzáth, J.: Plant macrofossils from the Hungarian Pleistocene III. Palaeobotanical study of Győrújfalu, Western Hungary

roremains, mainly inprints ofleaves, fruits (SKOFLEK & BUDÓ 1967, SKOFLEK 1968) and seeds of Celt is sp., Celtis cf. australis (JÁNOSSY 1979) of Günz-Mindel or Cromerian age from travertine limestones in Hungary. Some unpublished data of macroflora from the older part of Cromer interglacial-complex (Süttő, Dunaalmás, Les-hegy, Mogyorósbá­nya) and published results of studies on the younger part of the Hungarian Middle Pleis­tocene (Mindel or Elsterian glacial and Mindel-Riss or Holsteinian interglacial) (SKO­FLEK 1990) suggest the survival of several exotic species, e. g. Pteroccirya stenoptera and Lauras nobilis. All these plant remains came from travertine sequences in Western Hun­gary near our locality. There are only three localities from the Cromer interglacial-complex in Europe which are characterised by plant macro- and microfossils, molluscs and vertebrates. Comparison with those sites (Bilshausen, Voigstedt, East-Anglia) is rather difficult be­cause of the nature of the macrofossil-assemblage. However, the flora of Győrújfalu re­sembles the Pastonian IL, IV. and Cromerian IL, IV. of Cromer Forest Bed Series in East-Anglia. CONCLUSIONS Possible plant associations can be reconstructed from the diverse flora representing different habitats. The plant assemblages and their associations found in black and brown clays represent the patterns of aquatic and riparian vegetation of the infilling ox-bow lake and surrounding wetland area. The assemblage may have been parautochthonous (FER­GUSON 1995) representing the vegetation of the broader area. The reconstructed plant as­sociations (Table 2) were very similar for each sample with the exception of the associ­Table 2.
