In Argentina, scientists believe they have found some fossils that could belong to a titanosaur -- which is the largest creature to have ever walked on Earth.
Titanosaurs were a kind of sauropod dinosaur that stood on four legs, had very long necks, and were large in size.
So far, scientists have discovered 24 tail vertebrae and parts of the pelvic and pectoral girdle.
"It is a huge dinosaur, but we expect to find much more of the skeleton in future field trips, so we'll have the possibility to address with confidence how really big it was," said Alejandro Otero, study corresponding author and a paleontologist with Argentina's Museo de La Plata.
These gigantic dinosaurs were more than 122 feet long and weighed more than 77 tons, according to the scientists.
To put that in perspective, blue whales can reach a length of over 80 feet and African elephants weigh just about 9 tons.
