Muttaburrasaurus is a genus of dinosaur with a large, bulging crest-like nasal area.
Muttaburrasaurus could either walk on four legs or two, due to having three of the middle digits on each forelimb joined in a hoof-like pad to walk upon. The forelimb paw was long and broad with four digits total.
It had a long, triangular, flat head, with a large, strongly bulging nasal area on the top of its snout, called a bulla nasalis. The bulge was used to make calls and for display purposes.
It was equipped with a very strong jaw and shearing teeth, similar to those of the Ceratopsians, for eating tough vegetation.
It is classified in the Rhabdodontidae family, closely related to the Iguanadontids.
