Recently Discovered "Mummified" Dinosaur Is So Well-Preserved It Even Has The Skin And Guts Intact (Photos & Video)

This dinosaur was built like a tank. A member of a newly discovered species called nodosaur, it was an enormous four-legged herbivore protected by a spiky, plated armor. It weighed approximately 3,000 pounds. To give you an idea of how intact the mummified nodosaur is: it still weighs 2,500 pounds. Although how the dinosaur mummy could remain so intact for so long remains somewhat of a mystery, researchers suggest that the nodosaur may have been swept away by a flooded river and carried out to sea, where it eventually sank to the ocean floor.
