Helical burrow shapes produced by animals are known in the fossil record (e.g. Daimonelix by rodents, Xenohelix by a crab) and are explained in terms of functional morphology as structures aiding the movement of an animal through a vertical shaft.

Daimonelix when first discovered, in 1891, was thought to be confined to the elevated tablelands of central Sioux County, Nebraska. In the meantime its range has been extended and it is now known almost throughout the entire Arikaree formation, a tract probably about five hundred miles in diameter, situated in Nebraska, Kansas, South Dakota, Wyoming and Colorado. The more fibrous forms of ... For the helical burrows (Daimonelix) of the Miocene beaver Palaeocastor fossor, extra and/or unusual effort was required for the helical passage versus a straight passage. Compared to a vertical shaft, the extra effort was from an additional 137% (for a 25° helical incline) to an additional 100% (for a 30° helical incline).
