Graptolites were collected by bulk sampling of loose boulders. The sedimentary succession of the Mrákotín Formation has been reconstructed, in particular by detailed correlation with the biostratigraphically well dated, graptolite-rich successions in the Barrandian area and Thuringia. 112 graptolite species have been recorded, Pseudorthograptus finneyi sp. nov. was described. There is little difference between the graptolite faunas of the Hlinsko Zone and the Barrandian area, but the lithological successions of the two areas differ. Mrákotín Formation was deposited near the depositional site of the coeval formations of Saxo-Thuringia and West Sudetes, rather than near the Barrandian area.
