In some cases, structures similar to Zoophycos (Zoophycos-like; Fig. 3(C, E)) can be identified, but a conclusive identification Page 7 of 23 A c c e p t e d M a n u s c r i p t was difficult.The paleoenvironment influences trace-making behavior significantly, and progressively more evidence shows that this behavior follows scale-invariance properties. In this study, we focused on the definition of behavioral complexity in the trace fossil Zoophycos to explore its paleoenvironmental significance. Firstly, the fractal topography in Zoophycos was established by introducing virtual ...Firstly, the fractal topography in Zoophycos was established by introducing virtual tertiary lamellae. Next, a fractal dimension ( D ) model was proposed and the spatio-temporal evolution trend of the complexity of the trace-making behavior was established.

The trace fossil Zoophycos characterized by complex, three-dimensional morphology with systematic internal structures occurs throughout the Phanerozoic marine sediments. The specimens of Zoophycos examined herein consist of a downward and helical spreite and are a product of the excretory behaviour of endobenthic detritus feeders. They are divided into two basic types: pre-Jurassic and post ...Zoophycos is a characteristic trace fossil in the Mississippian in the Alborz Basin deposits of north Iran, and is described for the first time in the Mobarak Formation.

Ichnological taxonomy, which applies the principles of biological nomenclature to non-biological material, is governed by the International Code of Zoological Nomenclature. Thalassinoides suevicus, Tisoa siphonalis, Zoophycos isp. and Zoophycos brianteus, reported for the first time from the early Cretaceous of Algeria.

Firstly, the fractal topography in Zoophycos was established by introducing virtual tertiary lamellae. Next, a fractal dimension (D) model was proposed and the spatio-temporal evolution trend of the complexity of the trace-making behavior was established.

In contrast, the trace-fossil assemblage of the non-homogenized sequences has an average bioturbation intensity of 46% and is characterized by high abundances of Planolites , …

In deeper environments, fine-grained sediments accumulated mainly while settling from storm-induced suspensions. The lower Maastrichtian deposits contain abundant Zoophycos exhibiting two main morphotypes, skirt-shaped Zoophycos in deposits around storm-wave base and tongue-shaped Zoophycos in somewhat deeper sediments. The types differ in ...Zoophycos is a complex three dimensional trace fossil that is abundant in deep ocean sediments worldwide, but has not been described previously from Cenozoic continental margin deposits of Antarctica. In the ANDRILL 1B core drilled through the north-west McMurdo ice shelf, Zoophycos occurs in a 17m thick unit of interglacial sediments bounded above and below by glacial surfaces of erosion.Zoophycos is a complex trace fossil with a wide range of morphological variability (Olivero and Gaillard 2007; Fig. 9.11i). This ichnogenus ranges from simple and isolated lobes with spreite to commonly large and very complex structures with spiral morphology (Bromley and Hanken 2003).

X-ray radiographs were used to identify Zoophycos spreiten (Fig. 2, Fig. 3).These X-ray radiographs (Fig. 2) were produced at the Institute of Geosciences, Kiel, following the method described by Bouma, 1964, Löwemark and Werner, 2001.Plastic boxes were pushed into the half cut of the core, and the sediment slabs were cut out with a nylon string and placed directly on the X-ray film bags ...B.S. 2021).

Research highlights We study cyclicity of sediment features and Zoophycos from South China Sea. We characterize cycles at the short-term eccentricity, obliquity and precession. We interpret the relationship between the cycles and the East Asian monsoon dynamics. Monsoon is related to cyclical climatic change, environment and Zoophycos producer. We evidence the usefulness of Zoophycos in the ...ABSTRAcr-Well-preserved specimens of the ichnofossil Zoophycos were found in upper Eocene beds of Afales Bay (northern Ithaca, Ionian Isles, Greece).
