This “cast” led to the preservation of the Daimonelix. The burrowing beavers were about the size of woodchucks or smaller.

Overview Abstract Dating back to 255 Mya, a diversity of vertebrate species have excavated mysterious, deep helical burrows called Daimonelix (devil?s corkscrews). The possible …The first group is typified by the occurrence of large vertebrate burrows, mostly exhibiting a helical pattern with a terminal chamber (Daimonelix) or a low-angle ramp tunnel with a rounded end (that may or may not be enlarged). Associated trace fossils are rhizoliths, meniscate burrows, and rare insect trace fossils (ant nests and possible ...

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. We suggest that Daimonelix were used mainly for nesting or rearing young, because helical burrows of extant vertebrates are generally ...The first group is typified by the occurrence of large vertebrate burrows, mostly exhibiting a helical pattern with a terminal chamber (Daimonelix) or a low-angle ramp tunnel with a rounded end (that may or may not be enlarged).
