| Summary: | The fossil record of bryophytes is significantly sparser than that of other terrestrial plants. This fact may be caused by low fossilization potential, incomplete preservation that does not allow a detailed study, or the inability of paleobotanists of precise identification of bryophytes fragments. The presented diploma thesis summarizes the findings on the hitherto published macroscopic samples of the tertiary bryophytes of the Bohemian Massif (České Středohoří Mts.) together with the yet unpublished findings from the Most Basin. The main aim of the thesis is a detailed description of anatomical and morphological features of individual samples and their classification into recent taxa. A total number of 16 samples were described and classified into 15 taxa across the system, specifically into 3 classes (Haplomitriopsida, Jungermanniopsida, Bryopsida), 9 families (Frullaniaceae, Fissidentaceae, Mniaceae, Aulacomniaceae, Amblystegiaceae, Thuidiaceae, Brachytheciaceae, Plagiotheciaceae, Neckeraceae) and 8 genera (Frullania, Fissidens, Aulacomnium, Drepanocladus, Thuidium, Brachythecium, Plagiothecium, Homalia). Two samples were placed in the fossil genus Muscites (Muscites sp. 1, Muscites sp. 2), which stands outside the recent system. Key words: Bryophyta, Tertiary of the Bohemian Massif,...
