Diagnosis. Rarely branched, spiralled burrows; helix essentially vertical, consisting of dextral, sinistral or reversing coils, which are not in contact (modified after Bromley and Frey, 1974).
Remarks. The phrase “… coils, which are not in contact” is added to make a distinction between Gyrolithes and Ichnogyrus Bown and Kraus, 1983, amammal burrow from continental sediments, which was included in Gyrolithes by Jensen (1997),
