Such traces are commonly reported from marine paleoenvironments throughout the Phanerozoic. This occurrence, the first of its kind in the Maritimes Basin, provides further evidence for ...Key concepts in the study of trace fossils 1. (A) Preservational variants of the same ichnotaxon, reflecting emplacement in sediments of different consistency. (B) Different views of the same ichnotaxon reflect slight differences in the level of burrowing relative to the clay-sand interface.The trace fossil Zoophycos is characteristic of the Lower Devonian in the Longmenshan area of southeastern China. Three distinct storm-generated or induced types of sedimentary sequences bearing ...Zoophycos is a complex trace fossil. Hundreds of these fossils, very similar to the type ichnospecies, have been observed in Devonian to Cretaceous deposits. The detailed analysis of the characteristics of the traces has resulted in a detailed constructional model. The specimens of Zoophycos that we have studied were constructed upwards into ...Introduction. The different ethological modes of Zoophycos producer exerts ambiguity to the use of this trace fossil (in conjunction with sedimentological data) as an environmental indicator, especially in evaluating energy level, substrate consistency, and organic matter distribution or nutrient supply.

The names, Chondrites scoparius and Cancellophycus (both described between 1858 and 1873 from studies of the surroundings of Lyon, in France), and other specimens, such as Spirophyton (which were collected in the United States), were originally considered as synonyms of Zoophycos. ...Bioturbation structures are traces of animal activity that disturb the original sedimentary layering. They can include burrows, mounds, trails, and fecal pellets.

(Fig. 10f), Zoophycos isp. 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. ExpandAccording to the concept proposed by Seilacher (1964, 1967), ichnofacies are trace fossil assemblages that recur through long intervals of time and are typical of a given set of environmental conditions (Frey and Pemberton, 1985).Ichnofacies are named after a characteristic ichnogenus and may be recognized even if the namesake form is absent.The trace fossil assemblage of muddy pelagites and hemipelagites is mainly assigned to the Zoophycos ichnofacies, and locally to the distal expression of the Cruziana ichnofacies. Turbidites are colonized mostly from the top, determining an uppermost part that is entirely bioturbated, the spotty layer; below it lies the elite layer ...The trace fossil Zoophycos characterized by complex, three-dimensional morphology with systematic internal structures occurs throughout the Phanerozoic marine sediments.

(Photograph taken by Anthony Martin in Switzerland, 2003.) A composite trace (drawings plus writings) made by Dolf and me. 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.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).Continental trace fossils are better suited for classification as ichnocoenoses (Fig. 7). Continental ichnofacies—the Scoyenia, Mermia, and Coprinisphaera ichnofacies—are too broadly defined and poorly formulated based on what is being learned now from study of ancient and modern continental environments and tracemakers (e.g., Hasiotis, 2002, 2004, 2007; Hembree and Hasiotis, 2007 ...Shelf- and deep-sea chalks are composed of trace-fossil suites largely attributable to the Seilacherian Zoophycos Ichnofacies, with abundant occurrences of Chondrites, Zoophycos, and Planolites ...The paleoenvironment influences trace-making behavior significantly, and progressively more evidence shows that this behavior follows scale-invariance properties.
