Zoophycos was initially named as a plant genus by Massalongo 6,7 . As a trace fossil, Zoophycos is not necessarily the trace of a single genus or species of a worm-like organism, but rather is a preserved feeding pattern (a behavior) made under certain environmental conditions by an organism or different types of organisms with similar feeding structures and behaviors.The association of abundant microbial colonies with microbial molecular fossils within the spreiten suggests that trace fossils Zoophycos would be a multifunctional garden carefully constructed by the Zoophy Cos-producer on the mutual basis of food supply and the redox conditions. ExpandEarly Palaeozoic Dictyodora replaced by Mesozoic and Cenozoic Zoophycos). Ichnofabric-forming trace fossils need to be fully understood before they can be confidently applied to reservoir characterization of turbidite facies, but this study identifies the most important ichnotaxa in such settings and provides a framework for future research.The trace fossil Zoophycos is abundant in transgressive, shallow marine carbonates in the Middle Permian (Wordian) Khuff Formation of the Huqf-Haushi Uplift of Interior Oman. It often occurs as part of a complex (compound) trace fossil that comprises two integrated elements: (i) irregular galleries with straight to gently curved tunnels and …Zoophycos is a distinct and enigmatic trace fossil ranging in age from the Cambrian to the Holocene (Zhang et al., 2015).
