Zoophycos

The trace fossil Zoophycos is abundant in the shallow‐marine deposits (tempestites) of the Lower Devonian (Emsian) Yangmaba Formation in Ganxi of Sichuan, South China. It often occurs as part of complex trace fossils that comprise different integrated elements: scratch traces, simple to complex spreiten structures with marginal tubes (Zoophycos) and vertical tunnels..

(after Benton & Harper, 1997) The ichnofacies occurs in a range of water depths between the abyssal zone and the shallow continental shelf, in normal background conditions of sedimentation.Zoophycos gibi.), çakmaktaìlarl içinde gözlenmesi dikkat çekicidir Bitki fosillerinden ise nadir de Olsa çok iyi örnekler çakmakta§larl içinde bulunmu#ur.

Zoophycos appears to represent a useful proxy to characterize high and seasonal organic‐matter deposition and primary productivity in Neogene hemipelagic deposits. Trace fossils provide valuable palaeoenvironmental information in hemipelagic settings. This is particularly true in the case of Zoophycos, an easily recognizable trace fossil in core.Fig. 3.

Ichnogenera including Arenicolites, Calycraterion, Fucusopsis, Laevicyclus, Macanopsis, Ophiomorpha, Paleomeandron, Rhizocorallium, Stipsellus, Thalassinoides and Zoophycos are recovered from the Lower Limestone, Mottled Nodular Beds and Upper Limestone associations of the Lameta Formation of Jabalpur area.Among these, …The Zoophycos exhibits four differently-colored fillings, namely, brown, gray-white, gray, and black (Fig. 3). During sampling, a clear flat cross-section of Zoophycos was chosen for observation, and the size of specimens was determined. On the average, each sample was 3 mm thick, 6 mm wide, and 9 mm long, and the observed surface area was ...

It is demonstrated that the Zoophycos-producers from the complex types of Zoophycos in storm sequences were opportunistic organisms (r-strategists). This study reveals storm-generated physical and biogenic structures and textures and provides a good ichnological method to identify storm deposits.The Zoophycos producer filled its burrow with Coprolus-like fecal pellets, possibly complementing deposit feeding with microbial gardening and/or food caching. Data presented here provide useful ...
