Paleontologists are making a roaring discovery in South America.
Experts think the massive dinosaur fossils they found in Argentina could belong to one of the biggest creatures ever to roam the world. It is believed to be a 98-million-year-old titanosaur and may have been roughly 122 feet long. For comparison, the largest living creature today, a blue whale, can reach lengths of over 80 feet. A paleontologist on the mission told CNN they still have more of the skeleton to unearth to determine the dino’s full size.
