features similar to Daimonelix. Heer's fossil occurs in the Miocene of Switzerland, while Spirophyton and Spiraxis occur in the Che-mung of New York and Pennsylvania.

RT @FossilBonanza: #HowDidItLiveWeek Daimonelix, "the devil's corkscrew", was a spiral burrow excavated by an ancient land beaver, Palaeocastor. It used its robust incisors to carve its whirly home.

The ranchers and settlers of the region called them ‘fossil twisters,’ or ‘Devil’s corkscrews,’ inspiring Barbour to name them Daimonelix, sometimes spelled Daemonelix in his writings.' The original spelling of this word by E. H. Barbour (1892) was "Daimonelix," which he altered a little later to the familiar "Daemonelix," as used herein.
