Why Were Dinosaurs So Big Paleontology World 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. 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.
How Did Dinosaurs Get So Big Scientists Now Have The Answer During the cretaceous period – from 145 to 66 million years ago — theropod dinosaurs evolved across different continents, with the largest reaching roughly the same size, cullen adds. spinosaurus, with its notorious long snout and sail fin, is generally considered the largest of the bunch, but others weren’t far behind. 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. Most of the largest herbivorous specimens on record were discovered in the 1970s or later, and include the massive titanosaur argentinosaurus huinculensis, which is the largest dinosaur known from uncontroversial and relatively substantial evidence, estimated to have been 70–80 t (77–88 short tons) and 36 m (118 ft) long. Triceratops. triceratops was the largest ceratopsian dinosaur. this skeleton is on display in the dinosaurs gallery . weight: 13 tonnes. length: 9 metres. triceratops is among the world's most famous dinosaurs, known for its parrot like beak, three facial horns and large frill at the base of its skull.
