   The subgenera of Eoparastaffella have been studied together with morphologically very close Eoendothyranopsis in profiles of the Tournaisian-Visean boundary beds in the Mokra quarries (Moravia, Czech Republic). The profiles are composed both of the alternation of limestones and red to green shales and the alternation of biodetrital and biomicritic limestones with thin shale intercalations. The joint presence of shallow water bioclasts (foraminifers, algae, calcispheres, crinoids, rugose corals etc.) and deeper water fauna (conodonts - abundant gnathodids, Scaliognathus, trilobites) as well as apparent gradations suggest that most of the limestones can be regarded as calciturbidites. The sediments correspond to different parts of a halfgraben basin; they were deposited in the beginning of a compression regime cycle and represent a transition to overlying typical flysch sequences. The different facies are folded and convergent in complicated overthrust tectonics.
