Zoophycus
In deeper environments, fine-grained sediments accumulated mainly while settling from storm-induced suspensions. The lower Maastrichtian deposits contain abundant Zoophycos exhibiting two main morphotypes, skirt-shaped Zoophycos in deposits around storm-wave base and tongue-shaped Zoophycos in somewhat deeper sediments. The types differ in ...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 ...Zoophycus (trace fossil).

The distance between lamellae is 1.5 mm on average, surrounded by prominent marginal tube of 0.6 cm ...paramoudra flints. Other trace fossils (e.g., Chondrites, Muensteria and Zoophycos) occasionally occur in flints. Thus, flints can be employed as a means for observing the nearly invisible ichnofabric of the chalk in which the concretions formed. INTRODUCTION THE chalk of Europe is a weakly lithified, chemically pure, white, coccolith limestone.The slope, terraces, and plateaux from depths of 200 to 2000 m are referred to as the bathyal or deep-sea zone. The bathyal zone and the abyssal and hadal zones below it are referred to as the deep sea. In much of the hydrocarbon resource area of the North West Shelf, the sea bed lies in this depth zone. Sediments of the North West Shelf slope ...

Zoophycos is a profound and complex burrow system (Fig. 5), with one single opening from the sea-floor. It appears as a thin layer of bioturbated (disturbed) sediment, constituting lamina, with an outline that can be either simple or lobate. The thickness of the layer is between 2mm and 10mm, and its width may reach up to 2m.(hummocky cross stratified, Zoophycus burrowed, fine- to medium-grained, sandstone Storm Shelf, Hummocky Sequence ).

ichnogenus A group of trace fossils that is given a name because the similarity of the traces suggests they were made by closely related species of organisms. Ichnological taxonomy, which applies the principles of biological nomenclature to non-biological material, is governed by the International Code of Zoological Nomenclature.
