Conversely, the overall morphology of ichnogenera Cruziana D'Orbigny, 1842, Rusophycus Hall, 1852 and Didymaulichnus Young, 1972 has more diagnostic features in common with both morphotypes. Among them, the two elongate ichnotaxa interpreted as locomotion traces, i.e. Cruziana and Didymaulichnus , share more similarities with ‘morphotype A ...

An exceptional ichnofossil from the Upper Ordovician of southwestern Ohio shows characters consistent with previously described "trilobite hunting burrows" from Cambrian and Silurian strata.

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 ...The only detailed ichnological contributions are from Gibb et al.

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.
