Belemnites of the Bohemian Cretaceous Basin in a global context

Belemnites occur infrequently from the Upper Cenomanian through the Middle(Upper Coniacian in the Bohemian Cretaceous. Four species of the family Belemnitellidae PAVLOW, 1914 have been described so far. A typical boreal faunal incursion, represented by belemnites, happened five to six times in the Bohemian Cretaceous Basin (BCB). Praeactinocamax plenus immigrated during the Late Cenomanian Metoicoceras geslinianum ammonite Zone (plenus Event); there were two short-term incursions of P. bohemicus in the Late Turonian (Subplionocyclus neptuni to Prionocyclus germari ammonite zones) and an incursion of Goniocamax lundgreni in the late Early Coniacian (below and intra-Cremnoceramus crassus inoceramid Zone). A single belemnite fragment was recorded from the "Chlomek Beds"; Middle to Upper Coniacian. Bohemian Cretaceous belemnite systematics, palaeobiogeography (including palaeobiogeographic maps reconstructed), palaeoecology (induding the relationship to other coleoid groups - i. e. teuthids) and stratigraphy are discussed.
