BEHAVIOR(S): Domichnia (dwelling).

ENVIRONMENTAL SETTINGS: Marine and continental aquatic environments.

POSSIBLE TRACEMAKERS: Worms, arthropods.

GEOLOGIC RANGE: Cambrian–recent

ADDITIONAL REFERENCES: Ash and Hasiotis, 2013; See Gardet, Lugier, and Lessertisseur, 1957, for detailed remarks.

REMARKS: May appear similar to Palaeophycus, and some even regard this trace as that ichnotaxon. In modern freshwater environments these tubes are similar to those produced by midge fly larvae and other members of the Chironomidae.
