Question. The blue whale, presently the largest mammal, weighs about 2.27 times more than the largest dinosaur. Blue whales weigh about 1.362 \times 10 ^ { 5 } 1.362 ×105 kilograms. Using scientific notation, about how much did the largest dinosaur weigh? At 59 tonnes, plant-eating dinosaur had 'the largest reliably calculable weight' of any known land animal. The dinosaur Dreadnoughtus weighed 59,300 kilograms and measured 26 metres long. It was The original discovery, and classification, of Rhamphorhynchus is a case study in well-meaning confusion. After it was unearthed in 1825, this pterosaur was classified as a species of Pterodactylus, which at the time was also known by the now-discarded genus name Ornithocephalus ("bird head").Twenty years later, Ornithocephalus reverted to Pterodactylus, and in 1861 the famous British When you're talking in terms of tons, rather than pounds, it's easy to get carried away and carelessly attribute a weight of 100 tons to a newly discovered titanosaur, since 100 is such a nice, round, newspaper-friendly number. That makes it only about a fifth to a sixth the weight of its infamous cousin Tyrannosaurus rex—but some 40 times heavier than the largest previously known feathered dinosaur. Argentinosaurus, a titanosaur sauropod dinosaur from the Cretaceous period in Argentina. By the beginning of the Cretaceous period, about 145 million years ago, gigantic, plant-eating dinosaurs like Diplodocus and Brachiosaurus were on the evolutionary decline. However, this didn't mean that sauropods as a whole were destined for early 2RxMI2.
