There are only a few published reports of Zoophycos from New Mexico and these are primarily from Carboniferous strata.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 ...High-resolution radiocarbon records trace episodes of Zoophycos burrowing.

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.Download scientific diagram | Zonation of depositional types A, B, and C related to the Zoophycos ichnogenus in Mobarak Formation. from publication: Zoophycos ichnogenus distribution and ...Zoophycos. zooph Zoophycos.The Zoophycos ichnofacies and its main components, Zoophycos isp., Phycosiphon incertum and Chondrites isp. have been related to marine environments of low energy and oxygen. This situation is very common in shelf environments of the past, the most important oil source rocks and/or unconventional reservoir. The Early Cretaceous …May 15, 2011 · Research highlights We study cyclicity of sediment features and Zoophycos from South China Sea. We characterize cycles at the short-term eccentricity, obliquity and precession. We interpret the relationship between the cycles and the East Asian monsoon dynamics. Monsoon is related to cyclical climatic change, environment and Zoophycos producer. We evidence the usefulness of Zoophycos in the ... Zoophycos is a deep tier structure with several ethological interpretations, but consensus favors the interpretation of cache behavior developed by vermiform animals 27,28.Zoophycos ichnofacies was associated with chalky calcilutite sediment, interpreted as calcareous muddy contourites deposited during low-energy conditions (Hüneke et al., 2020). Increased energy in the environment led to a shift toward the first sandy contouritic facies and the establishment of the distal Cruziana ichnofacies with predominant ... 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 is a highly complex trace fossil consisting of a 2-20 mm thick spreiten burrow helically coiled around a central axis (Fig. 1a).Spreiten are sheet-like structures spread between the limbs of a U-tube. The U-formed marginal tube constitutes the active part of the burrow, which is lodging the probably worm-shaped producer animal (Fig. 1b).Zoophycos producers used this seasonal food source and show a cache behavioral strategy. During glacial periods upwelling was weak and oxygenation of bottom water decreased as evidenced by ...Zoophycos is a complex fodinichnial structure (Bromley and Hanken, 2003). The Palaeozoic Zoophycos are documented from shallow to deep-sea deposits, the Mesozoic forms in the deeper shelf and ...Hey all. Found this sort of trace fossil Im assuming, in some shale shelves. My initial thought was Gryphaea but it lacks the proper lines and structure to be a shell. Now Im leaning towards Zoophycos. Can anyone confirm if it is zoophycos, and help with the morphology of this specific find? Im u...This ichnoassociation forming the second Zoophycos-bearing level (Zl 2) in the lower part of the member, is dominated by Zoophycos and Chondrites and has the most abundant traces of feeding activity.Nov 15, 2021 · 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 ... 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 trace fossil Zoophycos has the shape of a low-angled helicoidal sheet constructed of numerous spirally radiating and adjacent dwelling burrows, each lined with retextured sediment derived from the adjacent or underlying beds. Such spiral sheets are here considered the products of a sea pen or closely allied organism with its trunk at the sea floor and its tubular stem suspended in, and ...In an interglacial section the Zoophycos material measures -21.9 0 00 , whereas the host material ranges from -21.2 to -21.4 0 00 . The minimal difference between Zoophycos and host material suggests that gardening plays an insignificant role. The gardening hypothesis is therefore rejected in favor of a cache model, where food is squirreled ...

Zoophycos is a complex fodinichnial structure (Bromley and Hanken, 2003). The Palaeozoic Zoophycos are documented from shallow to deep-sea deposits, the Mesozoic forms in the deeper shelf and ...The 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 ...A, T. isp. B, Zoophycos isp., and other bioturbation features are firstly found from the Lopingian at the northern Penglaitan section. (2) Trace fossil is a good indicator of bottom-water oxygen level and reflects that the bottom waters started to become anoxic and unfavourable for benthic macrofauna in the late Wuchiapingian, which is supported by …The Zoophycos ichnofacies is reported for the first time from the Lower Jurassic (Toarcian) deposits of Algeria.
