Eight species (including a new one), assigned to 5 genera of the holothurian sclerites from the Jurassic of the Wieluń Upland and of the environs of Łuków are described. The suitability of sclerites for the local correlation of lithological units is shown and their palaeoecological significance is pointed out.
