Zoophycos trace fossil.
Extract. The general theme of this chapter is the relationships between trace fossils and benthic oxygen availability in marine environments. Discussion is organized into three sections, which correspond to related yet distinct approaches to the analysis of ichnofossil/oxygen relationships. Type.

Zoophycos is a well-known trace fossil common throughout the Phanerozoic. Paleozoic forms show important differences in morphology and habitat …Feb 1, 2021 · Zoophycos is a distinct and enigmatic trace fossil ranging in age from the Cambrian to the Holocene (Zhang et al., 2015). Zoophycos with simple, planar U-shaped spreites is commonly recognised in Palaeozoic strata ( Miller, 1991 ; Jensen, 1997 ; Vinn and Toom, 2015 ). However, considering the extreme variability in the trace fossils attributed to the ichnogenus Zoophycos, it is wise to apply the results from the modern deep-sea to fossil Zoophycos with caution. Other trace fossils that have been studied in some detail in modern material include Tasselia (Wetzel and Bromley, 1996) and Nereites (Wetzel, 2002).
