A systematic account of highly diverse cyrtocrinid faunules from Upper Jurassic strata of Štramberk type (Oxfordian–Tithonian) in southern Poland (Polish Carpathians) is presented. Fourteen taxa ( Phyllocrinus malbosianus , Ph . stellaris , Ph. sp., Psalidocrinus armatus , Sclerocrinus compressus , S . polonicus sp. nov., Hemicrinus aff. kabanovi , Ancepsicrinus parvus gen. et sp. nov., Tetracrinus baumilleri sp. nov., Eugeniacrinites alexandrowiczi , E . cf. moravicus , E. sp., Eudesicrinus gluchowskii sp. nov. and Hemibrachiocrinus tithonicus sp. nov. are described and illustrated. Representatives of the genus Eudesicrinus , previously recorded only from the Lower Jurassic, are here shown to extend into the uppermost Jurassic. Other cyrtocrinids considered are common in Jurassic/Cretaceous strata across Europe. In the present faunules, isocrinid (Isocrinida), comatulid (Comatulida) and roveacrinid (Roveacrinida sensu Rasmussen, inclusive of Saccocoma ) crinoids are associated.
