Zoophycos trace fossil
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.Zoophycos and related trace fossils from the Chefar El Ahmar Formation, Upper Emsian-Frasnian Ia-Ib (Ougarta, SW Algeria) Article. Full-text available. Dec 2020; P GEOLOGIST ASSOC;1. Introduction. Zoophycos is among the most distinct trace fossils. As defined by Häntzschel (Reference Häntzschel and Teichert 1975), Zoophycos is a planar spreite marking successive, former positions of the burrow, present either as simple lobes or as ornate spiral structures, enclosed by a marginal burrow which may not always be evident (either not developed or not preserved).

Zoophycos trace fossils from lower ...Zoophycos trace fossil: Note: Coprolites, or fossilized feces, are also considered traces but do not have a formal classification. Skolithos trace fossil. An alternative trace fossil classification is similar to the Linnaean system, creating an ichnotaxa from an ichnospecies within an ichnogenus.
The comparison between shallow- and deep-marine diatomites indicates a regressive sequence in the deep diatomites, with abundant Chondrites and Zoophycos at the base of the succession grading downward into Thalassinoides-dominated trace fossil assemblage in the uppermost part, which is similar to the shallow-tier trace fossils of the two ...Trace fossils are ‘only’ the fossilised traces left by organisms living in the sediment but nonetheless are covered by the rules of the International Code of Zoological Nomenclature (Rindsberg, 2012). ...
