Occurrences of Zoophycos are described and figured from the Amberley Limestone (Oligocene) in North Canterbury. The structure consists of a flattened to markedly conical helical slab of sediment.

1 Introduction. The stable calcium (Ca) isotopic composition of marine carbonate archives (δ 44/40 Ca) was proposed to be an important palaeo-environmental and palaeo-oceanographic proxy, mainly because of the linkage between the Ca and C geochemical cycles. The continental weathering of Ca bearing carbonates and silicates …

This specimen shows clearly that it is Zoophycos in its earlier morphotype (although it hasn't a comparative scale) when it was smaller than the later ones in the evolution process , similar to the specimens from Zhang et al., 2015. excerpt from L. Zhang et al. 2015. Zoophycos macroevolution since 541 Ma. Scientific Reports, 5: 1-10Oct 9, 2015 · In the Cenozoic, Zoophycos took the shape of complex, irregular skirt-like spreiten in several whorls with many long marginal lobes and alternating primary and secondary lamellae (such as Zoophycos insignis 18, Zoophycos rhodensis 4) (Fig. 2o–s), which are largely preserved in the upper part of sandy turbidites, silty turbidites or deep-sea ... Zoophycos is thought to be formed by moving and feeding marine polychaete worms and can extend for up to 1 m, both horizontally and vertically in the rock. Zoophycos are an important part of the bedding plane waviness at 0.5-1 m scale, and thought to probably contribute greatly to the engineering stability of the rock mass.Trace fossils, including Zoophycus, Chondrites, and Planolites, have been identified in or just below the light-colored shale intervals (e.g., Lineback, 1968, 1970; Cluff, 1980).

An exception to the preference for interglacial intervals can be found in the lower part of the intensely bioturbated, glacial interval MIS 6, where a number of spreiten-like traces were also seen.The trace fossils occurring in the Katesar member are k-selective in nature (Zoophycos ichnofacies) which gradually shifts to r-selective traces like Skolithos, Ophiomorpha (Skolithos ichnofacies).
