Turbidites are colonized mostly from the top, determining an uppermost part that is entirely bioturbated, the spotty layer; below it lies the elite layer ...Apr 1, 2012 · Zoophycos is one of the most widespread but enigmatic trace fossils, especially with regard to the ethology of its three-dimensional (3-D) helically coiled spreiten (Wetzel and Werner 1981;Kotake ...

The trace fossil Zoophycos has long been considered an archetypical example of a deposit-feeding trace. The important discovery that at least some types of Zoophycos actively introduce surface ...Early Palaeozoic Dictyodora replaced by Mesozoic and Cenozoic Zoophycos). Ichnofabric-forming trace fossils need to be fully understood before they can be confidently applied to reservoir characterization of turbidite facies, but this study identifies the most important ichnotaxa in such settings and provides a framework for future research.Zoophycos in ANDRILL 1B: morphology and deposi-tional setting Morphology Components comprising the trace fossil Zoophycos include a spreite or lamina coiled around a central axis, which commonly is an axial structure, lamellae within the lamina, and an open marginal tube (Fig. 1). Within this basic structure there is wide variation, and manyThe trace fossil Zoophycos has been described from the Middle Triassic carbonates of the German Basin for the first time. It occurs in a calcilutite bed at the top of a shallowing-upward cycle ...

3.4. Trace Fossils The trace fossils observed in Amasiri Sandstone on course of this study belong to two ichnofacies viz: Cruziana and Zoophycos. Monocraterion, Crosspodia are ichnospecies of Cruziana ichnofacies while Zoophycos ichnofacies are represented by Lorenzinia and Zoophycos ichnospecies. Fig. 5a & b.Introduction. The different ethological modes of Zoophycos producer exerts ambiguity to the use of this trace fossil (in conjunction with sedimentological data) as an environmental indicator, especially in evaluating energy level, substrate consistency, and organic matter distribution or nutrient supply. The problem is even more sophisticate … ….

Zoophycos portrays a proximal-to-distal …Zoophycos ichnofacies: trace fossil association used to denote oxygen- and organic-limited settings that occur most frequently on the deep shelf to upper continental slope. The most common traces are complex feeding traces, including Asterosoma, Chondrites, Helminthopsis, Phycosiphon, Planolites, Scolicia, Thalassinoides, and Zoophycos.

Among trace fossils, Zoophycos is often proposed as an extended phenotype of its producer(s) (e.g., Miller III, 2002; Miller III, 2003; Olivero, 2003). It is therefore tempting to establish a direct link between the morphological evolution of Zoophycos and the (Darwinian) evolution of its tracemakers. However, convergent evolution complicates ...1 Institute of Earth Sciences, Academia Sinica, Taipei, Taiwan, ROC 2 Department of Geosciences, National Taiwan University, Taiwan, ROC * Corresponding author address: Dr. Ludvig Löwemark, Institute of Earth Sciences, Academia Sinica, Taipei, Taiwan, ROC; E-mail: [email protected] Recently proposed ethological explanations for the …Chondrites is the most common trace fossil after Zoophycos, occurring like tree-like branching ...
