Zoophycus

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 ...
