Behemoth Argentine dinosaur Dreadnoughtus made T-rex look puny

WASHINGTON (REUTERS) - The word big does not do justice to a massive, long-necked dinosaur that shook the Earth in Argentina about 77 million years ago.

Try colossal, enormous, gargantuan and stupendous - and you might come close to an accurate description of this behemoth, known to scientists as Dreadnoughtus schrani.

Scientists on Thursday announced the discovery in southern Patagonia of remarkably complete and well-preserved fossil remains of the dinosaur, which weighed 65 tonnes and measured 26 meters long with a neck of 11.3 meters and a tail 8.7 meters long.

Paleontologist Kenneth Lacovara of Drexel University in Philadelphia, who discovered the dinosaur and led the effort for its excavation and analysis, said the scientists calculated its weight on the basis of the bones in its upper arm and thigh.
