The genus Eocaudina Martin (Holothuroidea) from the Devonian of Poland

Abstract

The holothurian sclerites are here described for the first time from the Upper Devonian the world over and also for the first time from the Devonian of Poland. The sclerites found are assigned to the genus Eocaudina Martin. Several so far known species have been analyzed critically and three new ones, viz. Eocaudina gornensis sp. n., E. ovalis sp. n. and E. quinqueordinata sp. n. erected. The stratigraphic occurrences of particular species from the Upper Devonian are compared with the ·conodont zonation.
