Weighing 65 tons (equivalent to 7 T. rex), Dreadnoughtus is not just the largest dinosaur ever discovered, it's the largest animal known that ever walked the earth. The name 'Dreadnoughtus' alludes to the dreadnought, a type of battleship, and means "fears nothing". These massive dinosaurs likely had no natural predators, although multiple teeth of small theropods were found with the specimens, indicating a Dreadnoughtus carcass was a popular destination for scavengers.
First discovered in southern Patagonia in 2005 by Paleontologist Kenneth Lacovara, and unearthed over the course of four years, two incomplete Dreadnoughtus skeletons have been discovered to date. 70 percent of the skeleton has been recovered, as the specimens were likely buried quickly by a flood or mudslide. The unusually high completion of the skeleton - including most of the tail and neck, forelimbs and hindlimbs, and more - means it is possible to calculate the weight of the Dreadnoughtus with confidence.
The Cerro Fortaleza Formation, where the Dreadnoughtus specimens were discovered, was likely a humid, swamp-like environment with a high level of rainfall.
