Zoophycus
Zoophycos-bearing levels exhibit a less intense degree of bioturbation (between 1 and 2) in contrast to the Zoophycos-rich bed from the middle part of Unit 2.

Zoophycos from the Oued Fodda Formation outcropping in the Djebel El Bayadha section (Aïn Hadjela area).To date, a convincing metric marine-depth calibration of the Nereites or Zoophycos ichnofacies has not been devised. According to Frey and Pemberton (1985), the Zoophycos ichnofacies is typical of depths between 200 m and 2000 m, and the Nereites ichnofacies below 2000 m. The cited authors did not provide criteria for these calculations.

Thalassinoides, Zoophycus and Planolites, common burrow systems preserved at horizons within the Chalk; Thalassinoides is probably the work of a crustacean.The Zoophycos lobe is unusually narrow and elongated, being almost restricted to the fill of the earlier burrow. The marginal tube is partially preserved (arrows). B, closer view of the specimen at a point where only the Zoophycos spreite is silicified. C, cross-section, as seen in the righthand end of Figure B, showing the details of the spreite preserved as a ghost …Meaning of zoophycos. What does zoophycos mean?

Zoophycos ichnofacies is still enig-matic (Ekdale, 1992). Attempts to re-solve the question of the primary sed-imentary structures and other trace fossils associated with Zoophycos have not resulted in any way that is significantly useful in facies inter-pretation. This is aggravated by the apparent change in facies of Zoophy-Zoophycos je jedním z druhů stop po činnosti organismů. A zrovna jeden z nejzajímavějších. Jedná se o složitou 3D spirálu, kterou vytvořil pravděpodobně nějaký červ tím, že velmi pravidelně prožíral bahno. Seberte si nejbližší okolní kámen a koukněte se do něj.

The feeding mechanism of Zoophycos producers demonstrates non‐selection by particle size or quality. The characteristic morphology and mode of Occurrence of Zoophycos and the presence of pellets with pyroclastic grains imply that the Zoophycos producers were surface deposit‐feeders. They dwelt in a burrow within the sediment and ingested the grains with nutrient detritus on the sea floor ...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 ...…

Next, a fractal dimension (D) model was proposed and the spatio-temporal evolution trend of the complexity of the trace-making behavior was established. In application, the correlation of D to the paleo-water depth and substrate consistency of ...
