    It's been a month of dino discoveries, but this one may literally be the biggest. Paleontologists in Argentina announced that they have discovered the fossils of what they believe to be the largest dinosaur, the titanosaur. Based on the bones, they estimate the titanosaur was 65 feet tall and 130 feet long. The titanosaur clocked in at 77 tons, which means it weighed as much as 14 African elephants. Diego Pol, one of the dig leaders, said that although they have determined that the titanosaur roamed the earth over 90 million years ago and was likely an herbivore, there is more to learn. "Now we have discovered over 200 bones of a completely new species and therefore we will be able to study how these animals grew, how these animals moved on Earth," he said.
