Scientists Examine Dinosaur Skin
jd writes "Fossilized skin from a dinosaur in China is allowing paleontologists a better understanding of what dinosaur skin was like. A tear, caused by a predator, shows that below the scales of the Psittacosaurus was a thick hide comprised of 25 layers of collagen. Other than the multitude of layers, this is very similar in nature to modern shark skin. The gash caused by a predator allowed the skin and the soft interior to be fossilized along with the bones. This is not the same dinosaur that had been reported previously on Slashdot, which was found in South Dakota, although the process and extent of fossilization is very similar."

Somebody's a bit sensitive about dupes
Table-ized A.I.
Reading the 'Origin of Species' gives great insight into those ideas. It's gives pretty interesting explanations (though a bit outdated) on why some species seem to revert to old forms (such as why whales look like fish), and why some useful features stay the same through the ages seemingly unchanged. Go on, get it and take it one idea at a time. It's available to everyone as a free audiobook or free text

If only they'd built them with 26 layers!
