Estimating body size of extinct mammals presents problems when size can be estimated only by extrapolation. I examined the influence of phylogenetic, biomechanical, and statistical assumptions on body size estimates for 2 species of fossil castorids, the Pleistocene “giant” beaver Castoroides and the fossorial Miocene beaver Palaeocastor. Trapdoor spiders are masters of surprise, crafting cleverly concealed "doors" and striking when unsuspecting prey wanders. Subscribe: http://bit.ly/BBCEarthS...

Quite possibly, the Palaeocastor is an extinct prehistoric beaver that lived during the late Oligocene to early Miocene periods. It’s one of the strangest mammals to be discovered in Nebraska. Its basic form is an elongated spiral of hardened earth material. These puzzling structures were first found in Sioux County as tree-sized, screw-like underground formations.
