Stratigraphy is defined very broadly as the "science of rock strata.…concerned not only with the original succession and age relations of rock strata but also…with all characters and attributes of rock strata…and their interpretation in terms of environment or mode of origin, and geologic history" (Bates and Jackson, 1987, p. 649).The Glossifungites Ichnofacies was erected by Dolf Seilacher (the father of modern ichnology) in the midnineteen sixties to encompass burrows excavated into firm or compacted substrates.Zoophycos gives its name to the Zoophycos ichnofacies, an assemblage of trace fossils which is associated with the shelf break. Nevertheless, it is now appreciated that it has a somewhat more cosmopolitan occurrence that has changed through time. It is typically associated with deep marine muds and sands, often between turbidite beds.
