The paleoecological characterization of a plant assemblage from the locality Štilec u Žebráku (Upper Carboniferous)
Abstract
The relict Carboniferous occurrence - the locality Štilec near Žebrák - is situated on the southern margin of the Central Bohemian Carboniferous Basin. Fossil flora from a sandy porphyric tuff is represented by the following species: Corynepteris angustissima (STBG.) NĚMEJC 1939, Desmopteris alethopteroides ETTINGSHAUSEN 1854, Linopteris neuropteroides (GUTB.) f. minor POTONIE 1904, Sphenopteris flexuosissima STUR 1885, Kidstonia heracleensis ZEILLER 1897, Calamites (Stylocalamites) sp./ Asterophyllites longifolius (STBG.) BRONG. 1828 and Palaeostachya feistmantelii NĚMEJC 1953. This plant assemblage represents probably an early succession stage, a plant cover attaining about 1 m in height. It replaced the previous forest-type, the peat-bog vegetation. The change of the vegetation was evoked by an ecological event - for example: rise of the ground water level in the peat-bog or forest fires.
