The flora of the Stephanian C Ploužnice Horizon is very sporadic; only at Žďár u Kumburku, the finds are more common including the index species Callipteridium pteridium. Permian Kalná Horizon is situated at the western part of the Krkonoše Piedmont Basin. It contains very rare flora (Autunia conferta), whereas fauna (especially actinopterygian fishes) is more common. Fauna of the both Ploužnice and Kalná horizons is common and rather poorly preserved. Miospore assemblage with high content of bisaccate pollen grains belonging to the Upper Autunian DS (Disaccites striatiti) palynological zone (Clayton et al. 1977) have been found in the Kalná Horizon in Veselá locality. Trace fossils have been documented at two sites: 1, at the Desatero locality, where the probable fish/amphibian coprolites in carbonate claystone (quiet-water settings without in-fauna) were found; 2, at Ploužnice (?traces of insect larvae; fish/amphibian swimming traces).
