The distribution of the trace fossil Zoophycos in Quaternary marine sediments from the Arctic Ocean was studied in twelve piston and gravity cores retrieved during the Swedish icebreaker expeditions YMER80, Arctic Ocean-96 and LOMROG I & II.The Zoophycos appears to be of subsurface origin.

The Zoophycos Ichnofacies is characterized by complex fodinichnia (Zoophycos, and sometimes other deep traces such as Thalassinoides) in tiered arrangements. (after Benton & Harper, 1997) The ichnofacies occurs in a range of water depths between the abyssal zone and the shallow continental shelf, in normal background conditions of sedimentation.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...Zoophycos portrays a proximal-to-distal trend in the storm-dominated ramp sequence. In deeper parts of the ramp with long-term stable conditions and organic enrichment, Zoophycos producers selected equilibrium strategies (K-selected), whereas into the shallower parts they opted for opportunistic behavior (r-selected) due to short-term stable ...Zoophycos is one of the most complex, enigmatic and widespread trace fossils in Phanerozoic marine environments1-5. Zoophycos was initially named as a plant genus by Massalongo6,7. Since then, several morphological types, like J- or U-forms2, and ethologies, such as surface detritus-feeding8, refuse dump4,9, cache4'10, deposit-feeding2,11,12 ...

As example, Zoophycos was clearly identified several times along the studied sections (see a clear example in the bottom part of U1385A_7H_2 section), but this ichnotaxon was not observed in CT ...The first Zoophycos-bearing level (Zl 1) is characterised by an overall high bioturbation intensity reflecting a very high oxygenation rate and nutrient supply, allowing the development of large ... ….

the way of living of the Zoophycos animal. Struc-tures that according to Hantzschel (1962) are referable to Zoophycos have been described under many different names. The genus Zoo-phycos was introduced in 1855 by A. B. Massa-longo, who changed the name Fucoides bri-anteus Villa, 1844, to Zoophycos brianteus (Villa). The complex further history ...Trace Fossil Analysis. This definitive textbook by a renowned field observer and analyst of trace fossils concentrates on the most distinctive examples, mostly made by infaunal invertebrates in originally soft sediments. It covers the whole geologic column and ranges from deep-sea to shallow-marine and continental environments.

Zoophycos is a trace fossil with curved lines that arc out from a centerpoint and are the product of reworking of sediment along a bedding plane. During the late Paleozoic trace-makers producing large Zoophycos traces lived in shallow marine environments, making some of the largest examples of this trace fossil. The first specimenThe feeding mechanism of Zoophycos producers demonstrates non-selection by particle size or quality. The characteristic morphology and mode of Occurrence of Zoophycos and the presence of pellets with pyroclastic grains imply that the Zoophycos producers were surface deposit-feeders. They dwelt in a burrow within the sediment and ingested the grains with nutrient detritus on the sea floor ...

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 ...The marginal lobes of some Zoophycos might act as sulphide wells in close combination with the oxygenated water of the marginal tube (Broomley and Hanken, 2003). Zoophycos is a burrow with helicoidal spreiten, which is typically a deep-tier trace fossil (Buatois and Mángano, 2013; Buatois et al., 2017).

The Zoophycos ichnofacies is reported for the first time from the Lower Jurassic (Toarcian) deposits of Algeria. The trace fossil-bearing strata in the Ksour Mountains, northwestern Algeria, are an alternation of fine-grained limestones and marls. The assemblage is characterised by its low diversity, consisting of eight ichnospecies (Chondrites intricatus, C. sociology kucraigslist fairplay coloradowhat is osha root Zoophycos is a three-dimensional trace consisting of a central vertical shaft or tunnel (centimeters in length and usually 1 centimeter or less in width), and spiraling layers of lateral feeding traces (generally tens of centimeters in width).
