Rusophycus even shows that more than one kind of organism can make the same type of trace. Rusophycus is also found in the Triassic, long after trilobites went extinct.

The specimen above is “convex hyporelief”, meaning it is on ...Rusophycus is an ichnogenus comprising shallow burrows generally attributed to trilobites and other arthropods.

However, the styles and quality of preservation are consistent with a (very) shallow mixed layer and the presence of a firm substrate just beneath it.
