Paleontologists have just discovered the bones of the largest animal known in Argentina. When the researchers were first drawn to the site, they knew that there was something large buried there. Twenty-four large vertebrae, the pelvis, and pectoral girdle all indicated that it was a large dinosaur — but they didn’t know exactly how big. Now it is looking like it is a long-neck dinosaur that will be longer than 122-feet and over 70 tons! It could be larger than the largest known dinosaur right now. That dinosaur is a long-necked titanosaur named Patagontitan.
