Vaňková, Lucie ; Košťák, Martin (advisor) ; Marek, Jaroslav (referee)
The thesis deals with an complex overview of the Lower Cretaceous belemnites, and their occurrence in the Czech Republic, especially in Štramberk locality. First part provides a brief introduction to the Lower Cretaceous and to belemnite morfology with emphasis on internal skeleton especially of rostrum. Next chapter includes short review of morfometric analysis, which is the most important feature for taxonomy. The following part presents systematics and taxonomy of the Lower Cretaceous belemnite, and their paleoecological use as an indicators for paleotemperatures. There are also mentioned geographical occurrences and migrations of certain belemnite taxa and their stratigraphical evidence in the Lower Cretaceous sediments. The last part deals with the locality Štramberk, which is unique in the Czech Republic because of its stratigraphical evidence of the Lower Cretaceous belemnite fauna. Key words: Belemnites, Lower Cretaceous, systematice, palaeobiogeography, palaeoecology, Štramberk
