Untitled вђ Why Did Dinosaurs Get So Big And Pterosaurs Theory no. 3: dinosaur gigantism was a byproduct of cold bloodedness. this is where things get a bit sticky. many paleontologists who study giant plant eating dinosaurs like hadrosaurs and sauropods believe that these behemoths were cold blooded, for two compelling reasons: first, based on our current physiological models, a warm blooded. All dinosaurs shared this body shape advantage. but while two legs are good for running and so all predatory dinosaurs were bipedal four legs can support a much larger body. this is why the biggest bipedal dinosaurs, such as spinosaurus, tyrannosaurus and giganotosaurus, only weighed about seven tonnes.
Why Did Dinosaurs Get So Big Journalhow So we know that the impressive size of argentinosaurus and other top sauropods was not a matter of an abiotic factor like increased oxygen in the atmosphere or lower gravity. our explanation lies. Why were some dinosaurs so big? how did their environment play a role in their size? “we still don’t know much about gigantism in sauropods and in dinosaurs in general,” andreas jannel, a postdoctoral researcher at the museum für naturkunde in berlin, says. “it’s a very active field of research.”. The image stuck, and well into the 1960s dinosaurs were portrayed as sluggish, lumbering beasts that must have grown slowly to great size in a sort of benign hothouse where huge beasts reigned and. Sauropods are a unique group of dinosaurs. they had hollow bones, didn't chew their food, they had incredibly long necks, and likely possessed huge stomachs. these traits are theorized to be key in how they attained their enormous size. undoubtedly, their long necks allowed them to reach food other animals couldn’t, which made a bigger size.

Discover the secrets of dinosaur size and how it affected their survival, evolution and extinction in this fascinating article from bbc science focus magazine. Our retrocalculations estimated that t. rex took 15 to 18 years to attain full size—that is, a hip height of 3 meters, a length of 11 meters, and a weight of 5,000 to 8,000 kilograms. if that.
