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 …In Daimonelix, the basal chamber can be as long as the helix is deep, while ranging from 2° to 43° (e.g., Martin and Bennett, 1977;Meyer, 1999) or more (up to ~80°; see Barbour, 1892Barbour ...

Barbour continued his research on the Daimonelix problem in the 1890's and soon developed an elaborate phylogeny . l~ which . Fig. 1. Pine Ridge east of Five Points. Sioux County. Nebraska. Gering and lowerComparison is drawn between helical burrow casts in the Lower Beaufort and other recorded occurrences, in particular, Daimonelix, a beaver burrow from the Miocene of Nebraska. Fundamental similarities far outweigh differences to the extent that the Beaufort helical burrows may be grouped with the “daimonelices”.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 ... ….
