World's Largest Dinosaur
The "World's Largest Dinosaur" is the name of a model "Tyrannosaurus rex" located in the town of Drumheller in the Canadian province of Alberta. Built of fiberglass and steel, has a height of and a length of , considerably larger than the largest known specimens of the actual dinosaur which reached up to in length, and was up to tall at the hips. The dinosaur was built while former mayor Phil Bryant was in his term.
Sauropoda
Their body structure did not vary as much as other dinosaurs, perhaps due to size constraints, but they displayed ample variety. Some, like the diplodocids, possessed tremendously long tails, which they may have been able to crack like a whip as a signal or to deter or injure predators, or to make sonic booms. "Supersaurus", at long, was the longest sauropod known from reasonably complete remains, but others, like the old record holder, "Diplodocus", were also extremely long. The holotype (and now lost) vertebra of "Amphicoelias fragillimus" may have come from an animal long; its vertebral column would have been substantially longer than that of the blue whale. However, a research published in 2015 speculated that the size estimates of "A. fragillimus" may have been highly exaggerated. The longest dinosaur known from reasonable fossils material is probably "Argentinosaurus huinculensis" with length estimates of to .
