Kotake, N. 1992 07 15: Deep-sea echiurans: possible producers of Zoophycos. The trace fossil Zoophycos in the upper Pliocene deep-sea deposits (Shiramazu Formation) distributed in the southernmost part of Boso Peninsula, central Japan, appears to be a product of feeding and excretory behavior by surface deposit-feeders inhabiting middle bathyal depths. Ecology and anatomy of modern deep-sea ...A 425 ka long record from piston core GIK17925-3 taken in the northeastern South China Sea was used to study the environmental conditions controlling the distribution of the Zoophycos trace fossil.Normal grading, parallel lamination, and symmetrical ripples are developed in sandstone. Thin mudstone and phosphorite beds, syneresis cracks, and siderite nodules are common.

An ichnocoenosis (plural = ichnocoenoses) is an ecological assemblage of trace fossils that are the work of a single community of tracemaking organisms (Bromley, 1996).

Nevertheless, it is now appreciated that it has a somewhat more cosmopolitan occurrence that has changed through time. It is typically associated with deep marine muds and sands, often between turbidite beds.The ichnoassemblage, comprising Zoophycos, Thalassinoides, and Planolites is attributable to the Zoophycos Ichnofacies. The alternation of intervals with medium to well-preserved traces with completely biogenically homogenized facies reflects changes in substrate consistency related to changes in bottom-current velocity or to sedimentation.The ichnology of carbonate sedimentary systems is less well studied compared to that of siliciclastic systems. Shallow-marine carbonates differ from their siliciclastic counterparts by a number of criteria, such as the composition and distribution of trace-fossil associations, broad and very shallow facies belts with intense bioturbation and subaerial exporsure, and a strong impact of ...10.Stratigraphy 10 Any package of sedimentary strata bounded above and below by an unconformity (of any kind) is a SEQUENCE.

What does zoophycos mean? Information and translations of zoophycos in the most comprehensive dictionary definitions resource on the web. The distribution and character of mass flows, particularly on the North Atlantic margin, are described. On seismic records, mass-flow characteristics range from contorted internal reflectors and a hummocky surface to acoustically transparent lens-shaped deposits.The ichnogenus Zoophycos is relatively rare in Cambrian-age sedimentary rocks, being far more commonly encountered in post-Devonian, and particularly post-Paleozoic, strata. A new occurrence of Zoophycos from the Upper Cambrian Gallatin Formation of the Bighorn Mountains, north-central Wyoming, USA, is reported herein.

Occurrences of Zoophycos are described and figured from the Amberley Limestone (Oligocene) in North Canterbury. The structure consists of a flattened to markedly conical helical slab of sediment.

The fossil record is often used to infer phylogenetic history. Which of the statements accurately supports this assumption? 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.
