Exoskeletal structure and composition in selected arthropod groups of the Prague Basin
Šilinger, Matěj ; Fatka, Oldřich (advisor) ; Weiner, Tomáš (referee)
The thesis is focused on the study of the internal exoskeletal microanatomy of trilobites and phyllocarid crustaceans from Lower Paleozoic rocks of the Prague Basin. Two main methods are used for this study. The first method, etching of polished slices with ethylendiamintetraacetic acid (EDTA) has been used for the study of microanatomy of trilobite exoskeletons; this method is for the first time used on material from the Prague Basin. The second method, maceration in hydrofluoric acid has been used mainly for the extraction of "small carbonaceous fossils". This method is for the first time applied for the study of exoskeletons in phyllocarid crustaceans. Main goal of the thesis is to determine whether the exoskeletons of trilobites and phyllocarid crustaceans found in the Prague basin are suitably well preserved to be studied with above mentioned methods. Key words: arthropods, exoskeletal structure and composition, Prague Basin
