In addition, sectioned material indicates that these Rusophycus may have been open at the sediment-water interface, while the crisp preservation of both Rusophycus and Teichichnus, along with the preservation of such delicate morphological details as scratch marks, suggests that the sediment must have been relatively firm at the time the traces ...Rusophycus is a trace fossil allied to Cruziana.

As such, our joint posterior estimate for crown-group Panarthropoda ...These trace fossils, called Rusophycus, were made by trilobites digging straight down into the muddy bottom. The holes they left were filled in by sand. That's why the tracks sometimes look upside down. They're actually sand casts of the tracks.
