The trace fossil Zoophycos typically consist of one or more lobate spreiten arranged around a central axis, often marked by a vertical shaft (Häntzschel, 1975, Uchman, 1995).

Introduction The Devonian deposits of the Saoura valley (Ougarta) rest on a wide platform belonging to the northern Gondwanan passive margin ( Maillet et al., 2013 ), best-exposed outcrops of which are located in the Marhouma area. They form the famous "km 30" reference section (or "Marhouma section").

This shallow-marine environmental setting is in contrast with the deeper bathymetries in which lobed Zoophycos are recovered in post-Palaeozoic times.The assemblage of trace fossils comprising of vertical and horizontal traces of suspension feeders, as well as deposit feeders, led to the identification of three distinct ichnoassemblages, which pertains to mixed Skolithos–Cruziana ichnofacies, archetypal Cruziana ichnofacies, and low-diversity Zoophycos ichnofacies.Abstract. Many horizons in the Marnoso-arenacea Formation contain rare to abundant trace fossils at numerous localities. Slope, fan, and basin-plain deposits have trace fossils dominated by the Nereites ichnofacies but include taxa from the Zoophycos ichnofacies plus Ohphiomorpha and Thalassinoides.Zoophycos is a complex burrow with stacked tiers, in which the tiers are made of spreiten-adorned lobes that radiate outward from a central tube in a downward spiral to form a shape that looks something like a Christmas tree in three-dimensions. Each lobe contains a peripheral tube, with spreiten loops between the tubes.

Earliest trace fossils. Some of the earliest trace fossils are found in rocks that are around 3.5 billion years old, and preserved as structures referred to as stromatolites. These are macroscopic structures that have a dome-like shape. In them, wafer-thin mats of photosynthetic microbial mats (cyanobacteria) alternate with fine calcite mud.

7.1 Ichnofacies. Seilacherian ichnofacies are defined as trace fossil assemblages that recur through long intervals of geologic time and are more or less characteristic of a given set of environmental conditions (Frey and Pemberton 1984, 1985 ).

The distribution of these ...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.Beds with Cruziana are typically composite. Burrows were sometimes washed out and then recast by sand with primary structures. Formation as open surface furrows on an eroded and firmed mud, as postulated by others, is sedimentologically plausible in some instances but is unproven and seems biologically unlikely.
