Dating back to 255Mya, a diversity of vertebrate species have excavated mysterious, deep helical burrows called Daimonelix (devil's corkscrews). The possible functions of such structures are manifold, but their paucity in extant animals has frustrated their adaptive explanation. 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. An analogous aid for increased vertical mobility are the round stairways in mediaeval architecture.ture to the ichnogenus Daimonelix, although clearly the two were convergent designs (the original Daimonelix is Miocene in age and attributed to the fossil ...The mellow tones and chiming sparkle associated with these instruments is represented in a wide diversity of pieces whose styles and influences include fragments of classical forms in Mark Delpriora's Sonata, references to the mysteries of nature in Daimonelix, named after spiralling rock formations found in Nebraska, electronic music, rock ... Dating back to 255Mya, a diversity of vertebrates created mysterious deep helical burrows, often called Daimonelix (devil's corkscrews).
