Sponge spicules from the Lower Devonian (Pragian) of the Barrandian
Five distinct morphological groups of sponge spicules or spicule-like microfossils from the Lower Devonian (Pragian) Dvorce-Prokop Limestone are described. They include octactines type A and B, triactine spicules and dichodiaenes type A and B. Their possible taxonomical position and the presumed paleoecological importance are discussed.
