Ichnofossils from the Lower Palaeozoic of the Železné hory Mts.
 Doucek, Jan ; Mikuláš, Radek (advisor) ; Marek, Jaroslav (referee)
On five key sites of the Lower Palaeozoic of the Železné hory Mountains (Bačalský rybník, Bačalský mlýn, Palác, Rabštejn and Deblov) the detailed research involving the compilation of schematic lithostratigraphic profiles (exluding site Deblov) was conducted. Individuals of ichnotaxa Zoophycos that have maximum Middle Cambrian age were described on the site Palác. This is the third oldest finding in the world. Ichnotaxa Zoophycos was further described on the site Bačalský rybník, where they are exposed quartz siltstones, the equivalent of the Dobrotiv of the Barrandian area. Ichnofossils abundant in the study area are Skolithos, Pragichnus, to a lesser extend Phycodes and Monocraterion. Skolithos on the site Rabštejn occurs in extreme size (until 90 cm). On the site Deblov community of Skolitos ichnofacies on the area measuring hundreds of square meters were described. There was also performed ichnological imaging which showed proportional representation of each ichnotaxa. Study samples for microprobe showed differences in structure and chemistry of ichnofabrics up filling and surrounding environment.
