Daimonelix

These include the extinct kangaroo rat (Eodipodomys celtiservator Voorhies, 1975a) and the extinct beaver Palaeocastor (Peterson, 1906). The burrow of …For the helical burrows (Daimonelix) of the Miocene beaver Palaeocastor fossor, extra and/or unusual effort was required for the helical passage versus a straight passage. Compared to a vertical shaft, the extra effort was from an additional 137% (for a 25° helical incline) to an additional 100% (for a 30° helical incline).' 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,

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.Various forms of Daimonelix are now known to have been constructed by a variety of terrestrial vertebrates since the Late Permian, approximately 260 million years ago (Smith, 1987;Fischer and ...Some of the diversity of the burrow fauna can, in its turn, be resolved from trace fossils. Retallack (1990) studied the smaller burrows found on the devil's corkscrews (Daimonelix). They turned out to be constructions of dungbeetles. In modern burrows, as many as 250 dungbeetles can live in one marmot latrine (Bibikov 1989). Back to lobby ….

Introduction. The Lower Devonian ichnocoenosis from the Old Red Sandstone of Spitsbergen is dominated by arthropod trace fossils (Diplichnites, Merostomichnites, Siskemia, Cruziana, Svalbardichnus) besides trace fossils of unsure origin (Planolites, Beaconites) and is described in detail by Wisshak et al.
