It is predicted Perucetus would have been about 17-20m in length, which is not exceptional. But its bone mass alone would have been somewhere between 5.3 and 7.6 tonnes. And by the time you add in
An early and not especially large sauropod, it lived 160 million years ago, laid eggs and possibly lived in a herd. It weighed 13 tons and ate 1,150 pounds of vegetation a day. The model focuses
Pterodactyl, informal term for a subgroup of flying reptiles (Pterosauria) known from the Late Jurassic through the Late Cretaceous epochs (163.5 to 66 million years ago). Their wingspans ranged from 2 to 11 meters (6.5 to 36 feet), which makes them the largest known flying animal.
Supersaurus (meaning "super lizard") is a genus of diplodocid sauropod dinosaur that lived in North America during the Late Jurassic period. The type species, S. vivianae, was first discovered by Vivian Jones of Delta, Colorado, in the middle Morrison Formation of Colorado in 1972. The fossil remains came from the Brushy Basin Member of the formation, dating between 153 to 145 million years ago.
While it is true that the weight of Giraffatitan and Brachiosaurus have varied wildly over the years, the most recent estimates have been nowhere near the cherry-picked 80-tonne figure. Indeed, in
Dinosaur eggs came in many sizes. The smallest known dinosaur— crow-sized Microraptor (MY-kroh-RAP-tur)—probably had small eggs. As for big dinosaurs, scientists say eggs couldn't be much bigger than a soccer ball. A bigger egg would either crack from its own weight or have a shell so thick that it would stop fresh air from seeping
