Thick-Skinned The textured skin of a hadrosaur is shown. The 66 million-year-old duckbilled dinosaur mummy was found in Southwest North Dakota in 2004. It is one of only four dinosaurs ever found with fossilized skin. Now the fossil has yielded soft-tissue skin structures and organic molecules. Analysis further showed the dinosaur had thick skin, like an elephant's.
