Zoophycus
Zoophycos is a somewhat cosmopolitan ichnogenus thought to be produced by moving and feeding polychaete worms. [1] Appearance Zoophycos occurs in two forms, one planar, and one which resembles a corkscrew. [2] In the latter helicoidal form, successive turns have larger or smaller radii. Nov 30, 2015 · Zoophycos is a characteristic trace fossil in the Mississippian in the Alborz Basin deposits of north Iran, and is described for the first time in the Mobarak Formation. The vertical distribution ...

Middle Kinniny Limestone; the trace fossil Zoophycus. One hundred and sixty metres west of the pool and 4 m south of the path (which lies here on a low postglacial raised beach) lies the Middle Kinniny Limestone which is 1 m thick and displays Zoophycus markings in abundance in the top 15 cm.

Now I'm leaning towards Zoophycos. Can anyone confirm if it is zoophycos, and help with the morphology of this specific find? I'm under the impression that zoophycos morphology changed throughout the ages, and I'm trying to reverse ID the age of rocks I found it in since the geological maps of my area are extremely vague and lack detail.Possible influence of Zoophycos bioturbation on radiocarbon dating and environmental interpretationProses 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 well-known trace fossil common throughout the Phanerozoic. Paleozoic forms show important differences in morphology and habitat distribution with respect to the Jurassic, Cretaceous, and Cenozoic ones. Therefore, Early–Middle Triassic is considered a crucial time-span for the understanding of the evolution of this trace fossil.

In shales, only a subset of bioturbation features falls into formally named categories of burrow types, such as Chondrites, Teichichnus, and Zoophycus (Wetzel and Uchmann, 1998), burrows that are emplaced into partially consolidated muds.The Zoophycos ichnofacies ideally is found in circalittoral to bathyal, quiet-water marine muds or muddy sands, below the storm wave base, particularly in shelfal to slope areas (MacEachern et al., 2007, MacEachern et al., 2012; Buatois and Mángano, 2011, Fig. 12). Settings are generally free of turbidity flows and subject to oxygen deficiencies.
