Daspletosaurus ("frightful lizard") was a tyrannosaurid theropod dinosaur that was 26-33 feet (8-10 m) long and weighed perhaps 2-3 tons (3000 kg).
It had tiny horns behind its eyes and its arms were a bit longer than those of T. rex. It may have been an ancestor of Tyrannosaurus. This bipedal meat-eater lived in marshes by streams in what is now Alberta, Canada, during the Upper Cretaceous period, 76-72 million years ago. It may have preyed upon Triceratops. It was named by D.A. Russell in 1970. The type species is D. torosus.
