Dinosaur Skin

What dinosaur “skins” have recently been found?

There have been several discoveries of dinosaur “skin” in recent years. One was discovered several years ago by a teenager on his family ranch in North Dakota: a 67 million-year-old hadrosaur (duck-billed dinosaur) with actual fossilized skin, complete with scales and a suggestion of stripes. The dinosaur mummy was found in southwestern North Dakota in 2004; to date, it is one of only about four dinosaurs ever found with fossilized skin. Another one was found in China, complete with a tear caused by a predator. It also shows that below the scales of this Psittacosaurus was a thick hide comprised of 25 layers of collagen, which is thought to be similar to modern shark skin.
