Abstract: The basinal, or Godula sequence of the Silesian Unit of the Outer Western Carpathians incorporated in the present nappe structure is characterized by a considerable thickness of Lower Cretaceous dark-grey, prevailingly pelitic deposits. Barremian and Lower Aptian ammonites occur in several isolated fossiliferous beds. Non-calcareous dinoflagellate associations were analysed in the same beds to provide a correlation of both ammonite and dinoflagellate ranges. Where index ammonites are missing, associations of dinocysts become a key stratigraphic element in thick lithologically monotonous deposits. The composition of dinocysts also supports environmental and paleoclimatic reconstructions in the area studied.
