Zoophycus
The U.S. Department of Energy's Office of Scientific and Technical InformationZoophycos 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.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. These can be seen both in section and when the rock is …

Zoophycos is one of the most complex, enigmatic and widespread trace fossils in Phanerozoic marine environments 1,2,3,4,5. 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 ...Several oil shale beds, over 10 m thick, occur at the base of the first member of the Upper Cretaceous Qingshankou Formation (K2 qn 1) in the Songliao Basin. They act both as excellent source rocks for conventional oil and as potential oil deposit for shale oil production. Here we combine micropaleontology with organic geochemistry to investigate …Ichnofacies can provide information about water depth, salinity, turbidity and energy. In general, traces found in shallower water are vertical, those in deeper water are more horizontal and patterned. [1] This is partly because of the relative abundance of suspended food particles, such as plankton, in the shallower waters of the photic zone ...
