Apr 9, 2020 · The Glossifungites ichnofacies is characterized by low diversity and high density assemblages which include Fuerichnus, Palaeophycus, Arenicolites, and Skolithos. The ichnogenus Fuersichnus is a relatively rare trace fossil that has been documented from Triassic and Jurassic nonmarine deposits and only recently documented in marine deposits ... Characteristics and Implications of Three Ichnofacies Cruziana Ichnofacies poorly sorted, unconsolidated sediments deposited in moderate-to low-energy, sub- tidal settings (e.g, on marine shelves, below the effects of fair-weather waves) wherein rates of sedimenta- tion and/or erosion are moderate to low, and food resources are abundant in both ...the Skolithos ichnofacies and Chondrites, Thalassinoides, Planolites, and Rosselia which belongs to the Cruziana ichnofacies. Six lithofacies association were distinguished and interpreted as follows; swaly cross-stratified sandstone represents a middle shoreface environment, laminated shale representing offshore to lowernental tracks, giving rise to successive ichnofacies. Apart from the paleosurfaces, the ichnological content is rich and quite varied in paleosols and so are the tracks of insect nests, solitary or in groups in these paleosols.

The ichnofacies is a mixture of relict and overprinted ichnofossils. The Teredolites ichnofacies is characteristic of woodgrounds that represent omission surfaces developed on wood clasts, log jams, or peats and coals (Fig. 11). This ichnofacies is most common in such transitional settings as estuaries, delta plains, and back barrier environments.Ichnofaciès et caractères pétrophysiques de la série triasique du versant nord du Haut-Atlas, Maroc ….

Ichnofacies can be considered to recur throughout the Phanerozoic, regardless of the specific ichnogenera that comprise the suites.
