Abstract (in english)
   The Upper part of the Letná Formation (Ordovician, middle part of the Beroun Stage in the Prague Basin, Barrandian area) yielded very rich trace fossil assemblages. Their occurrence is limited roughly to the uppermost 100m of the formation in the central part of basin. The ichnoassemblages (composed of Rusophycus, Cruziana, Planolites, Palaeophycus, Rhizocorallium, Dydymaulichnus, Teichichnus, Curvolithus, a.o.) correspond to the Cruziana Ichnofacies. Massive, almost ubiquitous, taxonomically indeterminable bioturbation (e.g., bulge-like structures) are characteristic. This assemblage demonstrates a wide range of benthic organisms including trilobites. Different ichnoassemblages have been obtained from the lower part of the formation. Indeterminable bioturbation is usually weak.
   The ichnoassemblage (Chondrites, Phycodes, Planolites, Megagrapton, Teichichnus, Protopaleodictyon, Diplocraterion) is less diverse and does not contain any ichnotaxa whose presumed tracemarkers belong to "shelly fauna". 57 ichnospecies are described in the systematic part; Sinophycos sol ichnosp. nov. is established as new
