Dec 15, 2008 · The Daimonelix ichnocoenosis, with Daimonelix, Beaconites, small-to-large Katarrhedrites, and 5–10 mm diameter rhizoliths, is present in the lower profile of very organic-rich paleosols generally above the influence of the water table but subject to seasonally variable saturated and unsaturated conditions. The best-preserved and exposed ichnofossils are located approximately 1.6 km south of Lake Scott State Park in a road cut through an east–west trending ridge of Ogallala strata called the Devil's Backbone (Fig. 1).The road cut exposes ~ 23 vertical meters of rock composed chiefly of tan- to reddish brown-colored, moderately sorted, …DAIMONELIX.

[2] Palaeocastor was much smaller than modern beavers. There are several species including Palaeocastor fossor, Palaeocastor magnus, Palaeocastor wahlerti, and Palaeocastor peninsulatus.

Vertebrate burrows, interpreted as most likely constructed by mammals, are described from the Salt Wash Member of the Upper Jurassic Morrison Formation (Utah, United States) by Raisanen & Hasiotis (2018), who name new ichnotaxa Daimonelix martini and Fractisemita henrii (the latter potentially representing the burrows of a social mammal).The Daimonelix-building Palaeocastor sported large, flat incisors. It lived and, based on finds of bones of young beavers, raised its litters at the end of this straight chamber. The tall, tightly coiled spiral entrance forming the top portion of the burrow is now thought to be an ingenious method for helping to retain moisture and control ...

Dating back to 255Mya, a diversity of vertebrates created mysterious deep helical burrows, often called Daimonelix (devil's corkscrews). 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 surrounding sediments were so rich in volcanic glass that the groundwater was charged with silica, and plant roots became embedded in a glassy matrix (the hard, white exterior of the burrows). This “cast” led to the preservation of the Daimonelix. The burrowing beavers were about the size of woodchucks or smaller.
