Of all recurring marine ichnofacies, the Zoophycos Ichnofacies is most debated and least understood.

Six ichnofacies, varied in expression, are ...Zoophycos is a well-known trace fossil common throughout the Phanerozoic. Paleozoic forms show important differences in morphology and habitat distribution with respect to the Jurassic, Cretaceous, and Cenozoic ones. Therefore, Early–Middle Triassic is considered a crucial time-span for the understanding of the evolution of this trace fossil.[1] The downward transport of surface sediment deep into the sediment column by the Zoophycos-producing animal leads not only to large age differences between the Zoophycos structure and surrounding host sediment but also to large differences in age between different foraminifer species found inside the trace fossil. In the late Quaternary material from the southwestern Portuguese continental ...Firstly, the fractal topography in Zoophycos was established by introducing virtual tertiary lamellae.
