Zoophycus
The specimen shown below is a common type of movement trace fossil called Zoophycos. The animal (likely a worm) that made the trace probably lived in a burrow near the position indicated by the arrow. The clockwise swirling lines may indicate the sweeping motions of a feeding structure that gathered food from the sediment.Proses diagenesa merupakan salah satu hal yang penting dalam batuan sedimen. Salah satu bagian dalam diagenesa batuan sedimen adalah proses reworking butiran sedimen oleh organisme, atau yang dikenal sebagai proses bioturbasi yang menghasilkan fosil jejak.Zoophycos is a helical feeding trace fossil – the signature of some critter systematically mining the mud in its vicinity for digestible organic content.

Jan 27, 2017 · About 200 Zoophycos specimens, including 90 specimens studied in detail, have been analysed in the continuous Upper Cretaceous–Lower Miocene pelagic sedimentary type sections of the Gubbio area (the Contessa Highway, Contessa Quarry and Bottaccione sections, Northern Apennines). The sediments are reddish to grey limestones and marls of the Scaglia Group and marls with volcaniclastic deposits ... Zoophycos is a complex trace fossil with a wide range of morphological variability (Olivero and Gaillard 2007; Fig. 9.11i). This ichnogenus ranges from simple and isolated lobes with spreite to commonly large and very complex structures with spiral morphology (Bromley and Hanken 2003). It is known since the Cambrian (Olivero 2003).Explore janet.powell's photos on Flickr. janet.powell has uploaded 1273 photos to Flickr.Zoophycus.

Detailed studies of one burrow permit classification of the Zoophycos animal as a poly-chaete annelid. The genus Zoophycos Massalongo, 1851, is considered to comprise different sorts of traces.paramoudra flints. Other trace fossils (e.g., Chondrites, Muensteria and Zoophycos) occasionally occur in flints.

Zoophycos is a broad type of 3-dimensional structure constructed by marine infaunal animals. Palaeontologists and geologists have noted and described the structure in rocks for over 250 years (e.g. Häntzschel 1975) and it is now known from deposits ranging in age from Cambrian to Holocene (Alpert 1977, Ekdale & Berger 1978 ).picosensis; Zoophycos isp.
