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.The ichnogenus Zoophycos is relatively rare in Cambrian-age sedimentary rocks, being far more commonly encountered in post-Devonian, and particularly post-Paleozoic, strata. A new occurrence of Zoophycos from the Upper Cambrian Gallatin Formation of the Bighorn Mountains, north-central Wyoming, USA, is reported herein. Material consists of a ...Discovery and paleoenvironmental implications of a Zoophycos-group trace fossil (?Echinospira) from the Middle Pennsylvanian Sydney Mines Formation of Nova Scotia Duncan McIlroy 2006, Atlantic GeologyThe 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 about 0.5 cm 2.
Zoophycos: Sand and silt: Deep water, base of continental shelf, may be associated with turbidites: A series of horizontal burrows curving away from a central point. Figure 4.24 – Zoophycos burrows from the Swiss Alps. Image credit: Chris Spencer, CC BY-NC-ND. Nereites: Silt and clay: Deep water, open ocean: Meandering and spiraling …Zoophycos represents the feeding traces of deposit-feeding (eating organic particles from sediment), worm-like invertebrate (lacking a backbone) organisms. As a trace fossil, Zoophycos is not necessarily the trace of a single genus or species of a worm-like organism, but rather is a preserved feeding pattern (a behavior) made under certain environmental conditions by an organism or different ...Devonian occurrences of Zoophycos are often observed in successions representing shelfal deposits and have been interpreted as the first expansion of this trace fossil during the Paleozoic. Dense Zoophycos occurrences in storm-generated Paleozoic beds have been interpreted as the result of ecological opportunist strategy when the tracemaker exploited quiet, nutrient garden substrates after storms.The Zoophycos ichnofacies ideally is found in circalittoral to bathyal, quiet-water marine muds or muddy sands, below maximum wave base to fairly deep water in areas free of turbidity flows and subject to oxygen deficiencies. The trace fossils are characterized by: (1) low diversity, though individual traces may be abundant; (2) grazing and ...

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 ...…

Zoophycos is a characteristic member of the Zoophycos ichnofacies (Pemberton et al., 2001) and it represents the offshore environment, where it inhabits deep levels in the sediment (Solanki et al ...Zoophycos is found off NW Africa in water depths > 2,000 m, in sediments with C org contents of 0.3-1.8%. It is possible to recognize in the core sections all of the morphological spreiten types of Zoophycos which were described from ancient sediments. All of these spreiten are formed with two modifications classified as "U-type" and "J ...Detailed ichnological and petrographic analyses were conducted on two biostratigraphically-constrained intervals (11.9-11.3 Ma and 10.7-9.4 Ma) from the Middle-Upper Miocene stratigraphy of the Great Bahama Bank's leeward margin to assess spatiotemporal trends in paleoenvironmental conditions and reservoir properties in carbonate slope deposits. Six ichnofacies, varied in expression, are ...
