Scientists are excited about a 67 million-year-old duck-billed hadrosaur so well-preserved its skin and possibly some internal organs are intact. It’s not quite the makings for a real-life Jurassic Park but this is perhaps the best example of what dinosaurs were really like. These remains were discovered in 1999 by a 14-year-old boy in North Dakota, who is now a graduate student at Yale, working on his PhD in paleontology.
