(Scratch marks left between the arms of the U indicating that the organism lengthened and deepened the tube by transferring sediment from the floor of the burrow to the ceiling.) Tube diameter 10-12 mm. Rhyzocorallium is part of the cruziana assemblage associated with the neritic zone. From Dartford, Kent, England.
