A relative of Iguanodon, Muttaburrasaurus had the same spiked thumb and ability to walk either on all fours or on its hind legs. However, it differed in that it may have eaten meat as well as plants. Its name comes from the Australian town where it was first discovered. Muttaburrasaurus had an unusual rounded muzzle with a hollow chamber inside it the purpose of which is unknown. Perhaps it was to improve the sense of smell or to resonate sound and enable Muttaburrasaurus to make loud cries.
