A nodosaur was a large, lumbering herbivorous dinosaur that was robustly armored. Nodosaurs are related to ankylosaurs, another bulky plant-eater, except nodosaurs don’t have the trademark tail clubs. Even though they did not have tail clubs, they had spectacular armor that is preserved in this specimen with a level of perfection that almost defies explanation. This fossil is truly unique because rather than just a skeleton, most of what is preserved is its petrified body—a truly rare occurrence in the world of paleontology.
