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.
Dilophosaurus
"Dilophosaurus" was one of the earliest large predatory dinosaurs, a medium-sized theropod, though small compared to some of the later theropods. Slender and lightly built, its size was comparable to that of a brown bear. The largest known specimen weighed about , measured about in length, and its skull was long. The smaller holotype specimen weighed about , was long, with a hip height of about , and its skull was long. A resting trace of a theropod similar to "Dilophosaurus" and "Liliensternus" has been interpreted by some researchers as showing impressions of feathers around the belly and feet, similar to down. Other researchers instead interpret these impressions as sedimentological artifacts created as the dinosaur moved, though this interpretation does not rule out that the track-maker could have borne feathers.
