The complex and enigmatic trace fossil Zoophycos is recorded worldwide, from Cambrian to Holocene. The possible evolution of the ichnofossil has already been proposed by some authors, but their works concerned the very large group of trace fossils related to Zoophycos (structures that could be assigned potentially to several ichnogenera) recorded in several depositional basins.Ichnofacies are recurrent combinations of sedimentary facies and trace fossils; the Skolithos, Cruziana, Zoophycos, and Nereites ichnofacies, emplaced within marine softgrounds, characterize successively greater water depths (Figures 9 and 10).The use of trace fossils as a palaeobathymetric indicator exploits the fact that many, particularly ichnogenera, have a long time range, but are ...The ichnofossils assemblage of the sediment core can be assigned to the Zoophycos ichnofacies with a higher presence of Zoophycos in the entrance site of the gap and during glacial intervals.Zoophycos specimen from section AF3 is an exposed cross-section (Plate 1, Figs. 4 A and B).
