Daspletosaurus wilsoni was a large predatory dinosaur that lived during the Late Cretaceous period (about 77-75 million years ago). It was a member of the tyrannosaur family and was similar in appearance to its better-known relative, Tyrannosaurus rex. D. wilsoni was approximately 9-10 meters long and weighed about 2-3 tons. It had a large skull with sharp teeth, strong jaws, and binocular vision. It was a bipedal animal and its long, powerful hind legs enabled it to run at high speeds. D. wilsoni lived in what is now western North America.
