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. Dating back to 255Mya, a diversity of vertebrate species have excavated mysterious, deep helical burrows called Daimonelix (devil's corkscrews).
