Indeed, an accounting of previous and potential stratigraphic applications of ichnology would require nearly as much page space as would an inclusive summary of the myriad components of stratigraphy itself.Sedimentological features, together with body fossils and associated trace fossils (Planolites, Chondrites), indicate a shoreface habitat for the Zoophycos producer. This shallow-marine environmental setting is in contrast with the deeper bathymetries in which lobed Zoophycos are recovered in post-Palaeozoic times.

Zoophycos ichnofacies is still enig-matic (Ekdale, 1992). Attempts to re-solve the question of the primary sed-imentary structures and other trace fossils associated with Zoophycos have not resulted in any way that is significantly useful in facies inter-pretation. This is aggravated by the apparent change in facies of Zoophy-
