Abstract (in english)
   Sediments of the Šárka Formation are exposed at the Červený vrch Hill in Prague. The lower part of the outcrop shows biogenic structures belonging almost exclusively to the ichnogenus Pilichnus. Most of the distinctive traces (Planolites, Palaeophycus, Nereites) come from an interval rich body fossils of graptolites and phyllocarids. The overall character of the ichnoassemblage indicates ecologic stress, probably a low oxygen level, and only short-time fluctuations in the oxygen content.
