Article: Fish and amphibian trace fossils from Westphalian sediments of Bohemia

In the Radnice basin of Bohemia, fish and ethologically comparable amphibian ichnofossils of Upper Carboniferous (Westphalian C) age occur in limnic sediments that suggest humid, tropical conditions. Swimming trails of fish belonging to the subclass Actinopterygii, and probably to the order Palaeonisciformes, closely resemble trails in limnoglacial deposits of the Karroo Dwyka and Ecca Series in South Africa (Anderson 1970, 1976); the new trails are assigned to Undichna radnicensis ichnosp. nov. Footprints, swimming traces, and resting traces of labyrinthodont amphibians belonging to the order Temnospondyli (branchio-saurids or dissorophids) are associated with the fish trails. The swimming traces are assigned to Lunichnium gracile ichnosp. nov. and L. anceps ichnosp. nov., while the morphologically variable footprints are assigned to Gracilichnium (?) chlupaci ichnosp. nov.
