This undated artist rendering provided by the Carnegie Museum of Natural History shows the Dreadnoughtus. The dinosaur Dreadnoughtus had a 37-foot-long neck, 30-foot tail, and weighed an estimated 65 tons. In life, Dreadnoughtus was an herbivore that likely spent much of its life eating massive quantities of plants to maintain its enormous body size.
