A moment in time as an early Ordovician trilobite wandered along the sea flow moving sediment while possibly in search of food. The trackway leads to where a Rusophycus is located.

Cruziana and Rusophycus are commonly assumed to be trilobite trace fossils, although associated exoskeletons are almost invariably absent from host strata.
