Rusophycus.
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 ...

Euarthropoda is one of the best-preserved fossil animal groups and has been the most diverse animal phylum for over 500 million years. Fossil Konservat-Lagerstätten, such as Burgess Shale-type deposits (BSTs), show the evolution of the euarthropod stem lineage during the Cambrian from 518 million years ago (Ma).Neoichnological study and comparison of these bioturbation structures with the fossil record allow associating them as Cruziana- and Rusophycus-like traces, i.e. traces with features very similar to those of such ichnogenera. Since these ichnotaxa have been commonly interpreted as the result of the locomotion and resting of different kinds of ...A unique specimen of the trace fossil Rusophycus in the Moydart Formation (Ludlow) of the Siluro-Devonlan Arisaig Group of northeastern Nova Scotia la at least 35 cm long, 18 en wide and 8.5 cm deep.Recurring associations of the trilobite ichnogenus Rusophycus with various "worm" burrows suggest an interaction between the two tracemakers, specifically, capture of the worm by the trilobite. An exceptional ichnofossil from the Upper Ordovician of southwestern Ohio shows characters consistent with previously described "trilobite hunting burrows" from Cambrian and Silurian strata ...
