Well-preserved Zoophycos(?) trace fossil in bioturbated greenish gray claystone of Unit III (interval 188-1165B-58X-2, 65-90 cm).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. The 12 m long core offers a unique opportunity to study the response of the Zoophycos-producing animal to environmental variations over four glacial-interglacial cycles.

The trace fossil Zoophycos is characteristic of the Lower Devonian in the Longmenshan area of southeastern China. Three distinct storm-generated or induced types of sedimentary sequences bearing Zoophycos have been identified in shallow marine deposits of the Bailiuping Formation and the Yangmaba Formation. The type A deposit is composed of siltstones with shell concentrations and wave ripples ...

Spiral or planar radiate imprints, described as Zoophycos, Taonurus, Spirophyton, Pbysopbycus, Cancellopbycus, and Glossopbycus are regarded as fossil prostomia of sedentary marine worms of the Sabellidae. Methods for the study and description of these fossils, consistent with this mode of origin, are described.

Abstract. Many horizons in the Marnoso-arenacea Formation contain rare to abundant trace fossils at numerous localities. Slope, fan, and basin-plain deposits have trace fossils dominated by the Nereites ichnofacies but include taxa from the Zoophycos ichnofacies plus Ohphiomorpha and Thalassinoides.Sep 1, 2015 · Therefore, the two Zoophycos morphotypes, represented by J-and U-shaped marginal tube, likely exploited nutrient-rich substrate after the storm event end (e.g., Zhang, 2014;Zhang and Zhao, 2016). The transition to the first contouritic interval beds is marked by the gradual disappearance of Zoophycos and dominance of horizontal traces. This change is caused by a gradual sea level fall ...The tracemaker of Zoophycos is still a mystery, but evidence from the study of microbial and molecular fossils in Zoophycos spreitens indicates that the producer probably lives in a symbiosis with ...Zoophycos is a somewhat cosmopolitan ichnogenus thought to be produced by moving and feeding polychaete worms.

Zoophycos Massalongo, 1855 DESCRIPTION: Spreiten structures consisting of numerous distinct U-shaped, protrusive lobes of variable length, bordered by a marginal tunnel (i.e., causative burrow). Lobes coil spirally around a central axis, which may be a spreiten whorl structure. BEHAVIOR (S): Fodinichina; feeding burrows of deposit feeders.

These are similar in nature to the grain …

11.09.2020 г. ... My initial thought was Gryphaea but it lacks the proper lines and structure to be a shell. Now I'm leaning towards Zoophycos. Can anyone confirm ...Typically, at upward change from white flinty chalks with no marl seams to less flinty chalk with numerous marl seams (the Newhaven Chalk Member). The incoming of common Zoophycos flints and the presence of the zonal Uintacrinus socialis crinoid at the base of the Newhaven Chalk Formation are useful indicators in the field.']Abstract. Late-glacial palaeoclimate reconstructions from deep-sea sediment archives provide valuable insight into past rapid changes in ocean chemistry. Unfortunately, only a small proportion of the ocean floor with sufficiently high sediment accumulation rate (SAR) is suitable for such reconstructions using the long-standing age–depth model …Zoophycos ispp. are dominant in slope mudstones with synsedimentary slumping. The maximum ichnodiversity is recorded in the late Middle-Late Eocene; which is concomitant with a marked cooling trend.Seven ichnofabrics including Thalassinoides (Th), Zoophycos‒Phycosiphon (Zo-Ph), Skolithos‒Thalassinoides (Sk-Th), Zoophycos‒Diplocraterion (Zo-Di), Thalassinoides‒Rhizocorallium (Th-Rh), Zoophycos‒Arenicolites (Zo-Ar) and Chondrites‒Phycosiphon (Ch-Ph) have been identified in the studied succession.Zoophycos–Chondrites ichnofabrics expand turning point (Fig. 4d). herein were similar to Zoophycos–Chondrites ichnofabrics The Zoophycos–Thalassinoides–Palaeophycus ichnofabric in Storm II, small Chondrites were preserved in the interval mainly occurs in Sc of Storm V. Zoophycos is the dominant shales of Zoophycos beds (Fig. 3b, d).Zoophycos from both regions consists of planar spreite with major and minor lamellae and a cylindrical tunnel interpreted as a marginal tube and ⁄ or axial shaft. The cylindrical tunnel is herein considered to be an essential component of Zoophycos, and thus can be used to define and characterize the morphological variability of Zoophycos. ...

The Güneyce Formation is well exposed in the Lake District of southwestern Turkey. It was deposited in the early Miocene in the Neotethys ocean and contains a large variety of trace fossils. The following ichnotaxa were recognized: Chondrites intricatus, C. targionii, ?Cosmorhaphe isp., Helminthopsis isp., Helminthorhaphe flexuosa, Lorenzinia isp., …The Zoophycos material (230 outcrop photos showing Zoophycos and the samples of 50kg containing Zoophycos and other trace fossils) was obtained from the Westley Park Sandstone Member at the base of the Middle Permian (Wordian) Broughton Formation, at Black Head, Gerroa, in the southern Sydney Basin, southeastern Australia (Figs 1, 2).

Material consists of a single specimen preserved within quartz silt ...Zoophycos has been reported from several localities worldwide in Middle Devonian deposits generally affected by storm events in shoreface to offshore settings such as the Yarrimie Formation of ...within the Zoophycos spreiten, hosted in the Guadalupian (Middle Permian) glaciomarine greywacke of the Westley Park Sandstone Member within the Broughton Formation from the southern Sydney Basin of southeastern Australia. They are composed of non-sheathed (PF1) and sheathed (PF2)The Zoophycos group of trace fossils is common in Carboniferous to recent marine strata and sediments, and is a common component of ichnofaunas in the Visean and Namurian stages of England and Wales. A review of new and published records indicates that it is often present in limestones and sandstones of Chadian to Arnsbergian age. Thereafter it is less common, and restricted to clastic rocks.Zoophycos brianteus consists of an axial shaft along which the whorls form concentrically giving a stair-like appearance (Patel et al., 2009). Based on the lectotype of Zoophycos brianteus Massalongo, 1855, which is preserved in the Verona Museum, Olivero (2007), designated Zoophycos brianteus Massalongo, 1855 asZoophycos through geological time, therefore allowing Zoophycos trace-makers to escape extinction. This study offers new insights into the morphology and related ethology of Zoophycos , based on the discovery of new and well-preserved materials from two coeval but vastly different Permian paleoenvironmental settings - South China and southeastern …ABSTRACT. Neoproterozoic mafic dyke swarms are an important probe for reconstructing the evolutionary history of the Rodinia supercontinent. Here, we present detailed geochronological, geochemical, and Sr-Nd-Hf isotopic data to constrain the petrogenesis and geodynamic setting of Neoproterozoic mafic dyke swarms in the western Yangtze Block, South China.Zoophycos from both regions is composed of a marginal tube and a tongue-like spreiten complex, the latter itself consisting of primary lamellae in planar view and backfill structures (dark and ...The tiering structure involving dense Zoophycos ichnofabrics demonstrated that shallower burrows (e.g., Asterosoma, Palaeophycus, Cylindrichnus, Schaubcylindrichnus, Skolithos) reworked deep-tier ...

Paleontological survey in the remote Yukon-Charley Rivers National Preserve in Alaska led to the discovery of lobed Zoophycos from the lower Tahkandit Limestone (informally named Sandstone unit), an interval characterized by grayish-green glauconitic sandstone and conglomerate of coastal origin. The studied Zoophycos consists of a lobate skirt-like spreite bounded by a marginal tube.

The ichnofossils assemblage of the sediment core can be assigned to the Zoophycos ichnofacies with a higher presence of Zoophycos in the entrance site of the gap and during glacial intervals.
