World's largest animal bones

Archaeologists dug up fossils of what seems to have been the largest animal to ever walk the Earth early last week. They found the bones of a massive dinosaur in Argentina. When standing up straight, it would be as tall as a 7-story building. The dinosaur also weighed up to 77 tons. The scientist's guess is that the animal died in either a drought from dehydration or from getting stuck in the mud. Even though this thing was so massive and could have probably destroyed any other dinosaur in a fight, it was a peaceful herbivore.
