“The burrow system, a large spiral curved form parallel to bedding, comprises a series of continuous, zigzag-arranged, spindle-shaped burrows that collectively form a herringbone. Subsequently formed herringbone sets develop from the inside of previous sets in order to retain a spirally developed course.” (Yang, 1984, p. 708, trans. lift., partirri).
