Cruziana / Rusophycus
Vendor: Fossil Soup
SKU Number: SQ5776002
Rusophycus and Cruziana, most likely associated with a trilobite, from the Devonian of Pennsylvania.
A moment in time as a Devonian trilobite created a trackway (Cruziana) along the sea bed while probably foraging for food . The trackway leads to where a Rusophycus is located on the right side of the piece. The Rusophycus is very well defined, showing in detail where the trilobite rested for a while - maybe while eating.
Full dimensions are listed below.

Additional Information
Cruziana is a trace fossil consisting of elongate, bilobed, approximately bilaterally symmetrical burrows, usually preserved along bedding planes. It is found in marine and freshwater sediments.
Rusophycus is a trace fossil ichnogenus allied to Cruziana. Rusophycus is the resting trace, recording the outline of the tracemaker; Cruziana is made when the organism moved. The sculpture of Rusophycus may reveal the approximate number of legs that the tracemaker had, although striations (scratchmarks) from a single leg may overlap or be repeated. Both Rusophycus and Cruziana are typically associated with trilobites but can also be made by other arthropods.
