Scientists have announced the discovery of a 65 tonne dinosaur in Argentina that was one of the largest dinosaurs to ever walk the Earth. Believed to have existed about 77 million years ago, Dreadnoughtus Schrani weighed more than a Boeing 737 jet and was longer than a basketball court. Ben Gruber reports.
STORY: 77 millions years ago, this massive animal walked the Earth with nothing to fear, which is why paleontologists named the newly discovered dinosaur - dreadnoughtus. Kenneth Lacovara from Drexel University led the excavation in Argentina. After analysing the fossil remains, he says the giant dinosaur had the largest calculable weight of any animal ever discovered. Another giant dinosaur, Argentinosaurus, might have been larger but its scant remains do not allow a reliable weight estimate. Dreadnoughtus was a vegetarian but it had nothing to fear from its meat eating cousins. Lacovara said a single swing of its massive tail could have clobbered any predator foolish enough to attack it. Dreadnoughtus was a member of a group of dinosaurs called titanosaurs that are thought to have been the largest dinosaurs that ever lived.
