Late Turonian ophiuroids (Echinodermata) from the Bohemian Cretaceous Basin, Czech Republic RICHARD TORC & JIØÍ ÍTT Diverse ophiuroid faunules from the basal Teplice Formation, of Late Turonian age, exposed at Úpohlavy in the north- western part of the Bohemian Cretaceous Basin, northwest Bohemia, are based on only dissociated lateral arm plates, vertebrae and some other skeletal elements of the disc. The material can be ascribed to ten species, including a new taxon named Stegophiura? nekvasilovae sp. nov. Three additional species are represented in the material but these are left in open nomenclature. Relative species abundance is evaluated and discussed. • Key words: Echinodermata, Ophiuroidea, Upper Cretaceous, taxonomy, Bohemian Cretaceous Basin, Czech Republic. ŠTORC,R.&ŽÍTT, J. 2008.
