The Zoophycos ichnofacies is reported for the first time from the Lower Jurassic (Toarcian) deposits of Algeria. The trace fossil-bearing strata in the Ksour Mountains, northwestern Algeria, are an alternation of fine-grained limestones and marls. The assemblage is characterised by its low diversity, consisting of eight ichnospecies (Chondrites intricatus, C.

The marginal lobes of some Zoophycos might act as sulphide wells in close combination with the oxygenated water of the marginal tube (Broomley and Hanken, 2003). Zoophycos is a burrow with helicoidal spreiten, which is typically a deep-tier trace fossil (Buatois and Mángano, 2013; Buatois et al., 2017). Download : Download high-res image (2MB)Zoophycos is a deep tier structure with several ethological interpretations, but consensus favors the interpretation of cache behavior developed by vermiform animals 27,28.base), Zoophycos zone (wave base, turbidite depositional zone and slope), Nereites zone (deep water turbidite zone). Even though this classification seemed very useful, later studies showed that, trace fosil distribution is related to many factors, including substrate type, energy conditions, food availability, and preservationBy detailed comparison with body fossils, geochemical and palaeogeographical records, we conclude that the macroevolution of Phanerozoic Zoophycos is multi-affected by the global biodiversity ...

Zoophycos portrays a proximal-to-distal trend in the storm-dominated ramp sequence. In deeper parts of the ramp with long-term stable conditions and organic enrichment, Zoophycos producers selected equilibrium strategies (K-selected), whereas into the shallower parts they opted for opportunistic behavior (r-selected) due to short …

Zoophycos, and thus of the Zoophycos ichnofacies in Pa-leozoic shallow water deposits, is difficult to explain as resulting only from occasional breakdown in the correla-tion between depth and primary distributional controls. Thus 2) also appears to be untenable. Whether or not the Zoophycos ichnofacies concept can be applied to the Pa-

Zoophycos is one of the most complex and enigmatic trace fossils recorded in marine strata from Cambrian to Quaternary worldwide, which is invaluable for the study of Phanerozoic development of organism-environment interactions.

This is the case with Zoophycos funiculus Sacco (1886) (Olivero, 1994, pl. 1, fig. 4 published a photograph of the holotype).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 ...Feb 25, 2020 · In deeper environments, fine-grained sediments accumulated mainly while settling from storm-induced suspensions.
