Daimonelix.

Daimonelix (devil's corkscrews) and their creators. A, fossilized helical burrow of Palaeocastor, a terrestrial beaver that lived during the late-Oligocene early Miocene (23–34 Mya), from the Badlands of Nebraska, USA (United States Geological Survey).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.The cranial morphology of the small Oligocene beaver Capacikala gradatus is described on the basis of a well preserved, nearly complete skull and partial mandibles from the John Day Formation, John Day Fossil Beds, Oregon, USA. The only nearly complete skull known so far from the same area as the type specimen is described here in detail.RT @FossilLocator: For #fossilfriday I’d like to tell you about the weird fossil burrows called Daimonelix from the Miocene of Nebraska. They were made by Palaeocastor, an ancient beaver.

Large helical burrows named Daimonelix have been known for some time from the Oligocene and Miocene of Nebraska, USA. They extend to 2.5 m deep and have an upper entrance pit, a middle vertical spiral and a lower living chamber (Figure 10.44(a)).The burrow diameter is constant and the helix may be dextral or sinistral in the same locality. ...

Introduction. Underground dens and burrow systems are ecologically and sociologically important for a wide range of species. A total of 447 of the 777 genera of extant terrestrial mammals spend a significant proportion of their lives underground (Kinlaw 1999), varying along a continuum from the totally subterranean naked mole rats …Flickr photos, groups, and tags related to the "daimonelix" Flickr tag.Chad Arment (2021) Dr. Erwin Hinckley Barbour first examined the giant spiral-shaped fossils in northwestern Nebraska’s Miocene sediments in 1891. The ranchers and settlers of the region called them ‘fossil twisters,’ or ‘Devil’s corkscrews,’ inspiring Barbour to name them Daimonelix, sometimes spelled Daemonelix in his writings. The Sierra de Los Colorados, in northwest La Rioja province, Argentina (Fig. 1 A), is composed of a very thick Neogene sedimentary sequence that is mostly assigned to the Vinchina (older) and Toro Negro (younger) formations (see also Turner, 1964, Ramos, 1970).These sediments are part of the filling of a broken Andean foreland trough named …
