Trace fossils and depositional environments of the middle Turonian sandstones in the Upper Nysa K?odzka Graben (Sudetes, Poland) revisited

We provide the first reports of some rare trace fossils from middle Turonian (Upper Cretaceous) Sudety Mountains (SW Poland, Upper Nysa K?odzka Graben, D?ugopole Górne Quarry). These include burrows ? Ancorichnus isp., Asterosoma cf. ludwigae Schlirf, 2000, Phycodes Dactyloidites ottoi (Geinitz, 1849), Funalichnus strangulatus (Fritsch, 1883), palmatus Hall, 1852, , Phycosiphon incertum Fischer-Ooster, 1858, Planolites beverleyensis (Billings, 1862) and borings Entobia isp. Some body fossils, bivalves Brachidontes sp., Lima canalifera Goldfuss, 1836, Pinna ( ) cretacea (Schlotheim, 1813) Rhynchostreon suborbiculatum (Lamarck, 1801) are also reported. The fossil assemblage indicates a distal Skolithos ichnofacies proximal Cruziana ichnofacies, which characterize lower shoreface setting respectively. Sedimentation sandstones took place in shallow epicontinental sea normal salinity soft substrate, was well-oxygenated under low-moderate hydrodynamic conditions. presence oyster deposits studied suggests influence warm Tethys Ocean.
