Muttaburrasaurus was a large four-legged ornithopod herbivorous dinosaur genus that was able of rearing onto two legs. It was alike to Iguanodon in that its three middle fingers were joined together into a hoof-like pad for walking on. It is known from one partial skeleton establish at Muttaburra, Queensland, Australia, which also provides the creature's name.

Muttaburrasaurus had very influential jaws equipped with shearing teeth. These were probably an version for eating tough vegetation such as cycads. It also had an enlarged, hollow, upward-bulging muzzle that might have been used to make distinctive calls or for display purposes. However, as no fossilized nasal tissue has been found, this remains conjectural.
