A lower Visean trilobite association from limestones of the Liseň Formation in the Moravian Karst (Czech Republic) was studied in detail for the first time. The trilobites were obtained from a thin interval in the succession of the HadyŘicka Limest

The Devonian-Carboniferous boundary was coeval with the Hangenberg Crisis, which is regarded as a first-order mass extinction event related with large sea-level changes and widespread anoxia. This study aims to trace the geochemical paleoproductivity

The Devonian marine stratigraphic record is characterized by a number of bioevents – overturns in pelagic and benthic faunal assemblages, which are associated with distinct changes in lithology. The coincidence of lithologic and biotic changes can
