Lower Cenomanian trace fossils and transgressive deposits in the Cracow Upland

Abstract

Lower Cenomanian abrasion surfaces of the Cracow Upland abound in borrings of lithophags such as sponges, polychaetes, pelecypods and echinoids. Of many trace fossils occurring in these surfaces, the form Pseudopolydorites radwanskii ichnogen. et ichnosp. nov., attributable to polychaetes, has been established as a new one.
