Known as Devil’s Corkscrews, each structure is the infilling of a left- or right-handed spiral or helix that can extend up to seven feet into the ground. At the deep end of the spiral, a tunnel extends sideways and up at an angle. ( Wikimedia Commons)

 

 

Health Editor’s Note:I have to say this is amazing….and was a mystery to researchers for a long time.  Simply an extinct beaver’s burrow which is a spiral tunnel excavated in a left and right-handed strokes of the large incisors. The burrows extended down in a tightly coiled spiral and at the bottom the tunnels moved upwards at a 30 degree angle to create the chamber. There were good guesses as to how these spirals were made but the actual reason for these unusual fossil casts (ancient rodent burrow) are awesome!….Carol
