Palaeocastor behavior
Nov 15, 2010 · The extant beaver, Castor, has played an important role shaping landscapes and ecosystems in Eurasia and North America, yet the origins and early evolution of this lineage remain poorly understood. Here we use a geometric morphometric approach to help re-evaluate the phylogenetic affinities of a fossil skull from the Late Miocene of China. This specimen was originally considered Sinocastor ... Some 10,000 years ago, a giant beaver known as Castoroides ohioensis roamed the Earth alongside woolly mammoths and other ancient megafauna. But this giant species became extinct with the end of the Ice Age while its smaller cousin was able to live on to this day. And now scientists know why: This giant beaver simply didn’t chuck wood like ...Palaeocastor ('ancient beaver') is an extinct genus of beavers that lived in the North American Badlands during the late Oligocene period to early Miocene. Palaeocastor was much smaller than modern beavers. There are several species including Palaeocastor fossor, Palaeocastor magnus, Palaeocastor wahlerti, and Palaeocastor peninsulatus.

Migmacastor procumbodens and three species of Palaeocastor (P. fossor, P. simplicidens, and P. magnus) fall within the range of values observed for extant chisel-tooth diggers. Other members of the Palaeocastorinae (e.g., Euhapsis breugerorum and Euhapsis platyceps ) fall in the space between the extant chisel-tooth and head-lift digging groups.Trapdoor Spiders are a medium-sized mygalomorph (an infraorder of spiders), spiders that construct burrows with a cork-like trapdoor made of soil, vegetation and silk.

It lived during the Miocene Epoch between 23 and five million years ago, which makes it one of the oldest known beavers based on available fossil evidence.Description: Palaeocastor was one of the earliest known beavers. Unlike today’s aquatic beaver, Palaeocastor was terrestrial. It was about the size of a muskrat, about a foot long. Palaeocastor excavated and lived in 2.5 m long corkscrew shaped burrows.The Devil's Corkscrew is a fascinating example of trace fossil, which is a fossil that preserves the evidence of an animal's activity rather than the animal itself. Trace fossils can provide valuable information about the behavior and ecology of extinct animals. In addition to the Devil's Corkscrews, there are many other types of trace fossils. Palaeocastor’s helical burrows join several other biostratigraphic arguments exploring the fossil record’s relationship to the biblical record (Arment 2020a; 2020b; Ross 2012; 2014).

Another 32% are herbivorous, while humans belong to a small minority, just 3%, of omnivorous animals. The genus Palaeocastor includes species adapted for scratch-digging and/or chisel-tooth digging (with ontogenetic changes likely influencing some shifts in behavior).

And with that, America was introduced to one of its oddest ancestral creatures--a family of 22-million-year-old, spiral-burrowing land beavers named the Palaeocastor.
Why did Palaeocastor, Diictodon, and other species excavate deep helical burrows? Meyer (1999) calculated that the helical burrows of Palaeocastor required 36–61% more effort than straight burrows with the same incline, suggesting an adaptive function. He argued against the helix as a solution to predation pressure, or to prevent interference ...Aug 28, 2016 · Palaeocastor homes and Daemonelix burrows were some part of what drew paleontologists to the area in the late 1800s. Fossilized mammals from the Miocene Epoch, 23 million to 5.3 million years ago led to the creation of Agate in 1965.
