Zoophycus
In the Bay of Bengal, the Andaman and Nicobar Islands represent part of the Burma–Sunda–Java subduction complex. The Islands are composed of sediments ranging in age from Jurassic to Recent ...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 thinner ...Zoophycos is one of the most complex and enigmatic trace fossils recorded in marine strata from Cambrian to Quaternary worldwide, which is invaluable for the study of Phanerozoic …

It is demonstrated that the Zoophycos-producers from the complex types of Zoophycos in storm sequences were opportunistic organisms (r-strategists). This study reveals storm-generated physical and biogenic structures and textures and provides a good ichnological method to identify storm deposits.Trace fossils provide valuable palaeoenvironmental information in hemipelagic settings. This is particularly true in the case of Zoophycos, an easily recognizable trace fossil in core. At IODP site U1385, Zoophycos was found throughout an interval representing 1.5 Ma, covering 45 glacial-interglacial cycles mediated by obliquity (41 ka) and short‐term eccentricity (100 ka). Zoophycos is ...Zoophycos is more abundant in marl and limestone than in white chalk and chalky limestone. It is the purpose of the present study (i) to decipher the depositional environment of the lower Maastrichtian deposits, (ii) to describe the occurrence and morphology of Zoophycos burrows, (iii) to derive some ethological aspects of theA Permian Zoophycus trace fossil, viewed looking down on bedding. The typical corkscrew pattern usually trends downward into the sediment. Ellesmere Island. Cryptalgal laminae in digitate and domal stromatolites most commonly are flat to convex upward. These are particularly useful in Precambrian rocks.

Zoophycos are an important part of the bedding plane waviness at 0.5-1 m scale, and thought to probably contribute greatly to the engineering stability of the rock mass. ...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 ...

The fossil record is often used to infer phylogenetic history. Which of the statements accurately supports this assumption?Zoophycos isp. is a very complex trace fossil, with a wide variety of morphologies (Bromley, 1996; Knaust, 2009; Werner, 1981, Löwemark andSchäfer, 2003;Olivero, 2007;Löwemark, 2012). It ...smaller than Zoophycos, the broad morpho-logic similarity indicates that the two ichno-genera reflect generally similar behavior. The paleoenvironmental distribution of Zoophycos has been studied extensively. Orig-inally, Seilacher (1967) considered flat simple forms of Zoophycos indicative of intermediate water depth and more complex forms char- ….

These deposits are cyclic marl/limestone alternations, in which depositional sequences can easily be recognized. Two kinds of sequence have been studied: the marl/limestone couplet and the third-order sequence.Tables 2.4-2.6 explore idealized sedimentary facies in both clastic and carbonate environments. These facies models have been compiled by many geoscientists examining sediments in modern depositional environments.
