Researchers are carefully excavating a mummified Edmontosaurus dinosaur from a rock that has encased it for 65 million years. The 42 foot long herbivore was discovered on a ranch in Marmarth, North Dakota in 1999 and has since been unearthed and resides at the state museum. It is one of the most complete dinosaur mummies ever found.
