Abstract

The study involves a palaeoecological model for both the coals and associated sediments of the Lampertice Member of the Žacléř Formation in the Intra-Sudetic Basin, Czech Republic is proposed. The study area was an intramontane valley drained by a braided to low-sinuosity meandering river with a well developed floodplain. The river probably flowed to the northeast. Taphonomic analysis of the fossil record of various lithologies revealed the existence of autochthonous, parautochthonous–autochthonous and allochthonous plant associations. These associations served as the basis for the restoration of the original phytocoenoses colonizing different areas of the valley: (1) channel banks dominated by pteridosperms with subdominant calamiteans and ferns: (2) clastic floodplains colonised either by pteridosperms, ferns and calamiteans in well-drained areas or by arborescent lycopsids and ferns in poorly-drained areas: (3) mire (peat-forming) forests composed of arborescent lycopsids, ferns and sphenophylls: and (4) valley margin and slopes dominated by cordaiteans and pteridosperms.
