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.Zoophycos Massalongo, 1855 DESCRIPTION: Spreiten structures consisting of numerous distinct U-shaped, protrusive lobes of variable length, bordered by a marginal tunnel (i.e., causative burrow). Lobes coil spirally around a central axis, which may be a spreiten whorl structure. BEHAVIOR(S): Fodinichina; feeding burrows of deposit feeders. Within Zoophycos spreiten no homogeneous filling, fecal pellets, or any sign of re-exploitation of the minor lamellae have been recognized. No similar framboids have been observed outside Zoophycos spreiten. Therefore, the framboids are interpreted as the pyritized remains of microbial colonies within Zoophycos spreiten.

Shelfal expressions of the Zoophycos Ichnofacies, however, tend to comprise low-diversity suites of grazing and deposit-feeding structures, dominated by low-energy and/or facies-crossing components common to both the Cruziana Ichnofacies and the Zoophycos Ichnofacies (e.g., Zoophycos, Helminthorhaphe, Phycosiphon, Cosmorhaphe, Chondrites ...

The Zoophycos group of trace fossils is common in Carboniferous to recent marine strata and sediments, and is a common component of ichnofaunas in the Visean and Namurian stages of England and Wales. A review of new and published records indicates that it is often present in limestones and sandstones of Chadian to Arnsbergian age. Thereafter it is less common, and restricted to clastic rocks.

The Zoophycos ichnofacies (Fig. 19.13b) is characterized by complex fodinichnia like Zoophycos, and it may contain other deep traces such as Thalassinoides in tiered arrangements.

Methods for the study and description of these fossils, consistent with this mode of origin, are described.SUMMARY - Zoophycos -like structures associated with dinosaur tracks in a tidal-flat environment: Lower Jurassic (Southern Alps, Italy) - This study reports, for the first time, the occurrence of Zoophycos -like structures in the Lower Jurassic ofIn fluvial-tidal interacting settings, such conditions are possible in the restricted lagoon areas. Association of the Chondrites with Planolites and other deposit-feeding burrows points to a Seilacherian Zoophycos ichnofacies (Seilacher 1964; Howard and Frey 1984; Pemberton and Frey 1984; Frey 1990; MacEachern et al. 2012).
