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.The two best known named examples are Daimonelix Barbour and Gyrolithes De Saporta. Daimonelix is known only from continental, princi- pally fluvial, rocks, mostly from the Miocene of the Great Plains (Voorhies, 1975).
