(Good Morning America) Researchers believe they’ve found fossils of a dinosaur so large that it would have made Tyrannosaurus rex look like a pipsqueak.
Researchers announced this week they found fossils of a sauropod dinosaur that they estimate was the largest creature to have ever walked the earth.
Dr. Ruben Cueno, director of Museo Paleontológico Egidio Feruglio in Trelew, Argentina, said the dinosaur would have weighed at least 77 tons and grown to triple the size of a T. Rex. The bones were initially discovered by a farmer who spotted something unusual coming out of the ground.
