Muttaburrasaurus was a primarily herbivorous dinosaur from the early Cretaceous period of roughly 112 to 104 million years ago. The species is known from fossils found near Queensland, Australia.
The specimen reached up to 27 feet in length and weighed as much as 4 tons. Muttaburrasaurus had a large bulge on its snout between the eyes and mouth, which was associated with the sense of smell or the ability to make sounds. A beak, a flattened thumb spike, hooked claws and sharp teeth helped the creature forage. Similar to an iguanodon, the dinosaur likely walked on two or four legs.
