Rusophycus are created when a trilobite is stationary upon loose substrate. In filter-feeding trilobites such as Cryptolithus, the movement of limbs under the circular cephalic shield create distinctive trace fossils that mark this kind of feeding behavior, called Rusophycus cyptolithi.

Scale bar 4 cm.The sizes and shapes of this trilobite and the traces match closely. Five specimens have even been found where an articulated specimen of Asaphellus appears to be directly located over a specimen of Rusophycus carleyi within a thin bed of sandstone, suggesting that the trilobite animal may have been trapped on top of a trace that it had just ...

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 ...Inferences about the ventral anatomy and behavioural activities of trilobites can also be derived from the ichnological record, which suggests that most Cruziana and Rusophycus trace fossils were possibly produced by the actions of trilobites.geology of the flathead formation (middle cambrian) on the perimeter of the bighorn basin, beartooth mountains, and little belt mountains in wyomingTwo specimens of the trace fossil Rusophycus bilobatus from the Silurian Rose Hill Shale of Scott County, Virginia (PRI 76851).
