The lead dinosaur, a hadrosaur species known as Edmontosaurus Regalis, walked a few steps down from the trees. It rose up on its back legs and angled its face toward the foreign object, sniffing. It did not like the large, strange-smelling structure on the river bank. One instinct demanded flight. The herd should leave before any trouble occurred. Another instinct said that territory could not be yielded. The rest of the herd remained at the forest’s edge, motionless except for the gentle oscillations of their tails. 

A multinational group of paleontologists has described a new titanosaurian dinosaur, named Dreadnoughtus schrani, from Upper Cretaceous sediments in southern Patagonia, Argentina. It is the most complete giant titanosaur yet discovered, and provides new insight into the morphology and evolutionary history of these supermassive dinosaurs.

“With a body the size of a house and a weaponized tail, it would have feared nothing,” the scientist said. As a result, he chose the name Dreadnoughtus, meaning ‘fears nothing.’
