Rusophycus trace fossil from the Ordovician of southern Ohio. Scale bar is 10 mm. Rusophycus is a trace fossil allied to Cruziana [1]. Rusophycus is the resting trace, recording the outline of the tracemaker; Cruziana is made when the organism moved. [2] Both are typically associated with trilobites but can also made by other arthropods.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 ...Rusophycus are created when a trilobite is stationary upon loose substrate.
