Vertical, spiralling burrows termed Daimonelix (or Daemonelix or Daimonhelix) are known from sediments more than 20 million years old (dating to the Late Oligocene …Dec 18, 2019 · Daemonelix Trail Agate Fossil Beds National Monument This one-mile (1.6 km) trail at the west end of the park offers visitors a tour through through time. In addition to a dry land beaver's curious spiral burrows, the Daemonelix or Devil's Corkscrew, visitors see ancient sand dunes and fossil grassland soils called paleosols. Soil‐filled burrows do not support the hypothesis generated for Daimonelix that the helix would provide more consistent temperature and humidity as a result of limited air circulation in dry palaeoclimates.

Retallack (1990) studied the smaller burrows found on the devil's corkscrews (Daimonelix). They turned out to be constructions of dungbeetles.
