Erdei, Boglárka; Lesiak, Maria: A study of dispersed cuticles, fossil seeds and cones from Sarmatian (Upper Miocene) deposits of Sopron-Piusz puszta (W Hungary)

cones and seeds. Due to the mode of preservation mainly "cuticula dispersae" observations of the coalified organic debris that remained after washing out of the sediments were carried out. Fig. 3. Palaeogcographical reconstruction of the eastern margin of the Sopron-Kismarton basin in the "Upper" Sarmatian. The sedimentation took place in Gilbert-type delta in the northern part and in steep coastal environment in the south (after ROSTA 1993). Amplocypris sp.
