Mudstone/very fine-grained sandstone substrates are buried, dewatered, and compacted.It is finely laminated glauconitic marl, which is moderately bioturbated (BI = 3–4) and comprises dominantly trace fossils of deposit feeders, which include Gyrochorte robusta, Lanicoidichna isp., Teichichnus rectus, and Zoophycos brianteus. These trace fossils and fine-grained sediments point to deposition between fair weather and storm …Zoophycos is most common in sediments deposited during glacial times and when the sedimentation rate was intermediate (5-20 cm ka −1 ) and primary production was high and seasonal.Zoophycos is one of the most complex, enigmatic and widespread trace fossils in Phanerozoic marine environments 1,2,3,4,5. Zoophycos was initially named as a plant genus by Massalongo 6,7.Since then, several morphological types, like J- or U-forms 2, and ethologies, such as surface detritus-feeding 8, refuse dump 4,9, cache 4,10, deposit-feeding 2,11,12, and gardening 5,9, have been proposed ...The paleoenvironment influences trace-making behavior significantly, and progressively more evidence shows that this behavior follows scale-invariance properties. In this study, we focused on the definition of behavioral complexity in the trace fossil Zoophycos to explore its paleoenvironmental significance. Firstly, the fractal topography in Zoophycos was established by introducing virtual ...Dominance of Phycosiphon incertum vs Zoophycos in shelf environment: example from the transgressive Palermo Aike black shale deposits of the Austral-Magallanes Basin, Argentina.

The trace fossil Zoophycos can be considered a good example of a taxonomic problem, resulting from old interpretations and lack of studies on the type material.Zoophycos is a complex and enigmatic ichnofossil that has challenged generations of geologists and ichnologists for over a century. Till now, its producer or producers remain elusive.Some of the defined ichnoassemblages are assignable to a non-standard record of the Nereites Ichnofacies, and one in particular to the Nereites Ichnosubfacies, while another shows some characteristics coincident with the Zoophycos Ichnofacies. A transitional case between ichnofacies for the ichnological content of the unit as a whole, as ...INTRODUCTION. Zoophycos is a trace fossil whose exact organisation and significance have been discussed for long. According to the modern interpretations, it is a complex spreiten structure with a tremendous morphological variability (Bromley, 1996).Numerous descriptions have appeared since its first description in 1855 by Massalongo (see Olivero, Chapter 13), and this has led to a general ...El icnogénero Zoophycos y su valor sedimentológico y paleoambientalZoophycos is widely distributed in the marine strata of the Middle Permian Ruteh For- mation in the Alborz Mountain, Iran.

The distance between lamellae is 1.5 mm on average, surrounded by prominent marginal tube of 0.6 cm ...Zoophycos er et karakteristisk sporfossil for vore dybvandsaflejringer fra Sen Paleocæn og Eocæn. Diameteren kan blive over 0,5 m. Bygmesteren var en ukendt type orm, og formålet med den …The occurrence in the Yarrimie Formation of northeastern New South Wales, Australia, of well-developed trace fossils with Zoophycos affinities is noted. A general description of their nature, distribution and association with enveloping sediments is outlined, coupled with a detailed account of the nature of the outcrop in which they occur.C. Somite.

The producer of the lobed Zoophycos of the Yukon River is interpreted as a deposit-feeder that used sensory-driven, directed search for locating heterogeneously distributed trophic resources. The Zoophycos producer filled its burrow with Coprolus-like fecal pellets, possibly complementing deposit feeding with microbial gardening and/or food ...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.Zoophycos 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).De « Aalénien » à « zoophycos », plus de 5 000 mots des Sciences de la Terre et de l'Univers avec leur définition et leur traduction en anglais.
