Dreadnoughtus schrani (S/F)

Dreadnoughtos schrani was titanosaurid sauropod that lived in the Upper Cretaceous Period, circa 84-66 mya in what is now present-day Argentina. Dreadnoughtus schrani is the only species in its genus and is primarily known from two partial skeletons. Dreadnoughtus was estimated to be one of the largest terrestrial species known, with an estimated mass of 54 tons, and a length of 85 feet, with a height of 40 ft.


Dreadnoughtus was one of the species represented in a briefcase full of various dinosaur DNA vials taken from Isla Nublar after the eruption of Mt. Sibo. The case was seen being loaded onto a plane by a smuggler who had participated in the dinosaur auction. Dreadnoughtus was also seen in the form of a herd of animals maneuvering through a shallow lake in the Cretaceous period. Their movements through the water disturb nearby nesting Pteranodon, causing them to fly off.
