Zoophycos are spiral, concentric, lobate structures that are filled with mud or organic matter; they demonstrate deep water, low sedimentation rate, and high biotic diversity.The Zoophycos occurs in sediments deposited during the transition from ice-free open marine conditions to a fluctuating subpolar ice sheet suggesting that the Zoophycos-producing ani-mal colonized the seafloor during this transition. The 1.5m thick interval in which Zoophycos has been found (351.93-353.38 mbsf) occurs in 17.24m thick unit,PDF | On Jul 1, 1983, Andreas Wetzel published Biogenic Sedimentary Structures in a Modern Upwelling Region: Northwest African Continental Margin | Find, read and cite all the research you need on ...

Trace fossils include Chondrites, Zoophycus, and Terebellina. Sandstone content in the heterolithic facies is variable, decreasing gradually basinward. Sandstone injection features are not uncommon. The claystone facies consists of up to 10 cm thick beds of claystone, which are burrowed by Chondrites. Claystones are less common and …The Zoophycos ichnofacies and its main components, Zoophycos isp., Phycosiphon incertum and Chondrites isp. have been related to marine environments of low energy and oxygen. This situation is very common in shelf environments of the past, the most important oil source rocks and/or unconventional reservoir. The Early Cretaceous Palermo Aike Formation of the Austral-Magallanes Basin (Southern ...Large, well‐preserved Zoophycos specimens are abundant and widespread in the Amuri Limestone Group (Upper Cretaceous‐lower Oligocene) on the South Island of New Zealand. Although several previous workers have offered detailed descriptions of Zoophycos in the group, their hypotheses concerning its mode of production have flaws. We propose a new ethologic explanation of Zoophycos that avoids ...Multina–Zoophycos and multi-tier Zoophycos ichnofabrics, representing vertical migration of benthic faunas in pace with either distal event deposition or steadily accreted sea floor.

The bathyal zone and the abyssal and hadal zones below it are referred to as the deep sea. In much of the hydrocarbon resource area of the North West Shelf, the sea bed lies in this depth zone. Sediments of the North West Shelf slope ...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. ….

An ichnocoenosis (plural = ichnocoenoses) is an ecological assemblage of trace fossils that are the work of a single community of tracemaking organisms (Bromley, 1996). An ichnocoenosis is a lower level hierarchical unit compared to an ichnofacies, but has greater use for understanding the physicochemical factors ...

epochs of the cenozoic era Zoophycos is an ichnogenus thought to be produced by feeding worms. Zoophycos is found in deep marine muds and sands, often between turbidite beds. It is known from both the fossil record and deep sea sediment cores. The ichnogenus gives its name to a deep water ichnofacies. Bioturbation The Paleontology Portal.
