A consensus function for these unique structures has not been reached, but the recent discovery of deep helical nesting burrows created by (extant) monitor lizards provides a unique opportunity to interpret Daimonelix and morphologically similar fossil burrows.

' 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. The latter spelling has come into such general and accepted use that it is believed unwise to revert to the original form. Since the word is no longer regarded as a proper generic term,
