Daimonelix.

Palaeocastor ('ancient beaver') is an extinct genus of beavers that lived in the North American Badlands during the late Oligocene period [1] to early Miocene. [2] Palaeocastor was much smaller than modern beavers. There are several species including Palaeocastor fossor, Palaeocastor magnus, Palaeocastor wahlerti, and Palaeocastor …A world-renowned foundation dedicated to the preservation of big cats accidentally impregnates an African lioness with the semen of a man-eating Siberian tiger and releases her into Kenya's Masai Mara Game Preserve.

They were sand-filled spiral tubes up to 3 meters long with walls of white fibrous material. Such fossils were found in an area that at the time was considered the bottom of a dried-up ancient lake. The local population called them Devil’s corkscrews, and Barbour, believing he had discovered a new, hitherto unknown genus of freshwater fossil ...Helical burrow shapes produced by animals are known in the fossil record (e.g. Daimonelix by rodents, Xenohelix by a crab) and are explained in terms of functional morphology as structures aiding the movement of an animal through a vertical shaft. An analogous aid for increased vertical mobility are the round stairways in mediaeval …Daimonelix (alt. Daemonelix; pl. daimonelices). After considering whether it might be a fossil bryozoan or the case of an ancient worm (Barbour 1892), he proposed that they were fossil plants with large helical roots and horizontal rhizomes (Barbour 1896), while other scientists thought they might simply be concretions.

Burrow design varies widely among and within taxa, and these structures are adaptive, fulfilling physiological (and other) functions. We examined the burrow architecture of three scorpion species of the family Scorpionidae: Scorpio …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 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 …

The bones found within the corkscrews belonged to the rodents who dug them and became entombed within. The term Daimonelix was first used by Barbour in 1892 2 in describing the large, vertical, open spiral structures which he had located in Sioux County. That the discoverers were greatly im­ pressed and somewhat puzzled by these unusual fossils is shown in the following, passage from Barbour's type description: Pendant de nombreuses années géologues Ils ont été déroutés par des structures étranges spiraliformi, jusqu'à 2,5 m de profondeur, on trouve dans paléosols la Nebraska, États-Unis et qui ont été populairement appelé tire-bouchon du diable ( « Tire-bouchon Diable »), d'où le nom scientifique de "Daemonhelix« (Spirale du diable) .
