Skupien P., Vasicek Z. (2002) Lower cretaceous ammonite and dinocyst biostratigraphy and paleoenvironment of the Silesian Basin (outer Western Carpathians) // Geologica Carpathica. V. 53. N. 3. Pp. 179-189.
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.
