Dreadnoughtus schrani holds the place for the largest dinosaur ever discovered. This 65-ton (130,000 pounds) herbivore lived about 77 million years ago and died in Patagonia, Argentina. In 2005, Paleontologist Kenneth Lacovara discovered the first bone and worked with a team until 2009 to unearth the skeleton. Lacovara names it “Dreadnoughtus,” which means “nothing to fear,” because although it was a plant-eater, its massive size and weaponized tail would have protected it from any carnivores.
