The oldest Mesozoic nearshore Zoophycos: evidence from the German Triassic1. Introduction. Zoophycos is among the most distinct trace fossils. As defined by Häntzschel (Reference Häntzschel and Teichert 1975), Zoophycos is a planar spreite marking successive, former positions of the burrow, present either as simple lobes or as ornate spiral structures, enclosed by a marginal burrow which may not always be evident (either not developed or not preserved).To date, a convincing metric marine-depth calibration of the Nereites or Zoophycos ichnofacies has not been devised. According to Frey and Pemberton (1985), the Zoophycos ichnofacies is typical of depths between 200 m and 2000 m, and the Nereites ichnofacies below 2000 m. The cited authors did not provide criteria for these calculations.Multina–Zoophycos and multi-tier Zoophycos ichnofabrics, representing vertical migration of benthic faunas in pace with either distal event deposition or steadily accreted sea floor.

Zoophycos has often been interpreted as a feeding trace of worm-like invertebrates (Häntzschel, 1975; Olivero, 2007; Seilacher, 2007; Zhang et al., 2015). The Zoophycos ichnofacies is named after the homonymous ichnogenus and is located on the continental slope between the Cruziana and the Nereites ichnofacies (Osgood and Szmuc, 1972 ...

The Zoophycos ichnofacies ideally is found in circalittoral to bathyal, quiet-water marine muds or muddy sands, below maximum wave base to fairly deep water in areas free of turbidity flows and subject to oxygen deficiencies. The trace fossils are characterized by: (1) low diversity, though individual traces may be abundant; (2) grazing …The highly bioturbated, muddy, very fine to fine quartz sands of the Wenonah Formation were deposited mainly in the offshore zone of an inner shelf, below storm wave base. Distinctive trace fossils include Rosselia socialis and a planar form of Zoophycos . The Mt. Laurel Formation consists of two lithofacies.Ichnofacies can provide information about water depth, salinity, turbidity and energy. In general, traces found in shallower water are vertical, those in deeper water are more horizontal and patterned.

The Pottsville Group is a Pennsylvanian-aged cyclothemic succession containing nonmarine shales, marine shales, siltstones, sandstones, coals, marine limestones, and chert ("flint").Zoophycos illustrates, how the trace- maker adopted itself with environmental sequences. This reason, owing to optimal conditions, has caused that the abundance of Zoophycos was high in the Transgres-Ichnological analysis enabled us to document an abundant and diverse trace fossil assemblage, with ten ichnogenera, probably corresponding to alternations between the Zoophycos ichnofacies and the distal expression of the Glossifungites ichnofacies: Arenicolites, Chondrites, Diplocraterion, Halimedides, Palaeophycus, Planolites, …
