Thus reflect relatively deep-sea deposits and represent sedimentation from pelagic and hemipelagic suspension settling on quiet sea floors. The laminated structures, pelagic fauna (rich in ammonites), disorderly belemnites and thin beds indicate short duration of ...The Zoophycos Facies, cliaracterized by the roostertail- like trace fossil of the same name was proposed for an environment which was “sublittoral to bathyl, below wave base, and without turbidite Sedimentation” (Seilacher 1964, p. 311). It should be noted that Seilacher (1964, fig. 7) listed four deep-water deposits containing Zoophycos, and that in 1967 he …Zoophycos found in the Trubi Formation of Zanclean age (Pliocene) at Scala dei Turchi, in the Rossello composite section (Sicily). 300 years earlier (!) these unusual marks on rocks were observed ...Zoophycos is a somewhat cosmopolitan ichnogenus thought to be produced by moving and feeding polychaete worms. Zoophycos occurs in two forms, one planar, and one which resembles a corkscrew. In the latter helicoidal form, successive turns having larger or smaller radii.

The Palaeozoic Zoophycos are documented from shallow to deep-sea deposits, the Mesozoic forms in the deeper shelf and ...Zoophycos is one of the most widespread but still enigmatic trace fossils, especially with regard to morphology and ethology surrounding its 3-D helically coiled spreite structures. The genus Zoophycos is systematically revised based on the systematic researches of the literature with detailed description and plate from 1855 to 2011.The known Skoorsteenberg ichnofauna differs significantly from the conventional marine shelf (Cruziana), slope (Zoophycos), and basin plain (Nereites) ichnofacies. Two elements ( Gordia , Helminthopsis ) are typical of the (fresh) lacustrine Mermia ichnofacies ( Buatois and Mángano, 1995 ); others will surely be discovered.The complex and enigmatic trace fossil Zoophycos is recorded worldwide, from Cambrian to Holocene. The possible evolution of the ichnofossil has already been proposed by some authors, but their works concerned the very large group of trace fossils related to Zoophycos (structures that could be assigned potentially to several ichnogenera) recorded in several depositional basins.Zoophycos. Massalongo, 1855. DESCRIPTION: Spreiten structures consisting of numerous distinct U-shaped, protrusive lobes of variable length, bordered by a marginal tunnel (i.e., …The sedimentation of limestones bearing gutter cast structures is related to gravity flows probably linked to storm activities. These processes favoured the remobilization of sediment at the sea floor, as well as oxygen input to deep waters, as shown by the record of trace fossils including Zoophycos, Ophiomorpha, Chondrites and Diplocraterion .Zoophycos is used in environmental reconstruction, mostly for the interpretation of the paleobathymetry and the paleo-oxygenation in bottom waters. Zoophycos now has been discovered in two outcrops of Valanginian to Lower Hauterivian age rocks in the southern part of the Bucegi Mountains (Southern Carpathians).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. Zoophycos was only found in two cores taken at more than 2 km water depth on the slope of the Lomonosov Ridge, but was absent in cores obtained at shallower depth, confirming earlier observations ...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 …Zoophycos is most common in sediments deposited during glacial times and when the sedimentation rate was intermediate and primary production was high and seasonal. Occurrences of Zoophycos elsewhere support a similar relationship with seasonal organic‐matter deposition. This is particularly significant considering that seasonality of organic ...Zoophycos is a complex three dimensional trace fossil that is abundant in deep ocean sediments worldwide, but has not been described previously from Cenozoic continental margin deposits of Antarctica.Zoophycos trace fossil in the Mississippian of Ohio, USA. This rock sample is from the upper Logan Formation of eastern Ohio. The curving grooves are part of a trace fossil called Zoophycos, a distinctive feeding trace with an overall spiral morphology (for example, see: ...Computer modeling of trace fossils (Skolithos, Thalassinoides, Planolites, Zoophycos, and Phycosiphon) and ichnofacies (Skolithos, Cruziana, and Zoophycos ichnofacies) is undertaken to assess the ...Pa (Palaeophycus); Th (Thalassinoides); Zo (Zoophycos) Full size image. Conclusions. 1. The digital image treatment described here has been applied to core sediments from the IODP Expedition 339, Site U1385, allowing modifications in certain image features such as contrast, brightness, vibrance, saturation, exposure, lightness, …Pleistocene climate variations have been widely studied during the last decades due to their importance to understand how the orbital changes affected the ocean/atmosphere dynamic and the palaeoenvironmental conditions. Particularly, some time periods are of special interest, as the case of the Marine Isotope Stage (MIS) 19 as a …

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,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. They range from simple, isolated spreite lobes ( Miller, 1991 ) to highly complex spiral structures. Several ichnogeneric names are available for this array of forms, but as the necessary revision has yet to be undertaken, the ichnogenus Zoophycos will be used for the material published herein. The spiral forms may reach diameters exceeding 1 m.B - Gen - er al ized geo log i cal map of the Bardo Unit (mod i fied af ter Oberc, 1957 and Haydukiewicz, 2002) in clud ing the lo ca tion of the Paprotnia Beds. - "Occurrence of the trace fos sil Zoophycos from the Up per Viséan Paprotnia Beds of the Bardo Struc tural Unit ( Sudetes , SW Po land )"Many lobate spiral Zoophycos appear to have radiating ribs or spokes crossing the spreite between the bundles of minor lamellae, and thereby replacing the major lamellae. This is the case with Zoophycos funiculus Sacco (1886) (Olivero, 1994, pl. 1, fig. 4 published a photograph of the holotype).

The trace fossil Zoophycos is abundant in transgressive, shallow marine carbonates in the Middle Permian (Wordian) Khuff Formation of the Huqf-Haushi Uplift of Interior Oman. It often occurs as part of a complex (compound) trace fossil that comprises two integrated elements: (i) irregular galleries with straight to gently curved tunnels and interconnected shafts, and (ii) simple planar to ...The Zoophycos normally occurs from nearshore to off- scratch traces probably served for feeding (fodinich- shore in the Devonian, which was the first bloom of nia) and/or moving (repichnia), while the Zoophycos this trace fossil in the Palaeozoic (Miller 1991; Neto represents deposit feeding. de Carvalho & Rodriguez 2003; Gaillard & Rache- A ...…
