Upper Silurian - Lower Devonian Chitinozoa from the subsurface of southeastern Poland

This paper is a taxonomic and biostratigraphic study of the Chitinozoa from the Upper Silurian-Lower Devonian deposits (Rhenish magnafacies) found in the boreholes from southeastern Poland. The chitinozoans are referred to 46 species of 12 genera. Nineteen species are described as new: Ancyrochitina aurita, A. bullispiha, A. lemniscata.. Angochitina longispina, Anthochitina radiata, Conochitina invenusta, Desmochitina spongilcricata, Eisenackitina barbatula, E. cepicia, E. crassa, F. cupellata, E. fimbriata, E. lacrimobi/is, E. pi/osa, Gctlandochitinalublinensis, Hoegisphaera velata, Linochitina longiuscula,L.subcylindrica, and Margachitina gratiosa. Their stratigraphic and correlative values are discussed. Chitinozoan frequency and distribution in the sections, as well as associated fossils are considered.
