    The diploma thesis presented deals with paleoecological, biostratigraphical and sedimentological research in the most important locality of the Chýnice Limestone - Čeřinka near Bubovice village. The research was carried out during the years 2006-2010. Multidisciplinary approach has been applied during the fieldwork as well as in the subsequent laboratory research. Such an approach brought a lot of valuable knowledge. The contact between the Zlíchov and Chýnice Limestone has been described and characterized for the first time within this thesis in this locality using sedimentological, biostratigrafphical and geochemical data. Among others, microfacies analysis has been carried out and the sedimentary succession the of Chýnice Limestone has been described and sedimentary environment has been interpreted. During my research I was able to gather the largest collection of fossils with the exact stratigraphic position, which was ever collected within the Chýnice Limestone (2500 pcs). Fifty new taxa in total have been recorded from the Čeřinka locality during my research, representing almost 80% increase of taxa known from this classic locality. Numerical analysis of the fauna diversity development of the Chýnice Limestone revealed an increase of the total diversity in time and in the same time decrease of..

    Palynology, microfacies and biostratigraphy across the Daleje Event (Lower Devonian, lower to upper Emsian): new insights from the offshore facies of the Prague Basin, Czech Republic

    The Zlíchovian/Dalejan boundary interval (Emsian, Lower Devonian) of the Pekárek Mill section was studied employing biostratigraphy (dacryoconarid tentaculites, conodonts) and palynology (chitinozoans, prasinophytes, scolecodonts) and microfacies analysis in order to shed more light on the timing and characteristics of the Daleje Event. The results of our study stress the great importance of the base of the Nowakia elegans Zone for the substage level division of the Emsian. Onset of the Daleje transgression is linked with higher terrigenous input, and coinciding changes in the chitinozoan assemblages were recorded at this level. The transgression at the base of the N. elegans Zone preceded the main transgression taking place in the N. cancellata Zone; it can be correlated with the Upper Zlíchov Event. For the first time, Emsian chitinozoans and a jawed polychaete fauna are described in detail from the Prague Basin and can be correlated with other northern Gondwanan regions. The family-level composition of scolecodont assemblage confirms the dominance of paulinitids in the peri-Gondwanan realm.Fil: Tonarová, Petr.
