TDR's Daily Dino Facts! Muttaburrasaurus!

Muttaburrasaurus is known from one partial skeleton found at Muttaburra, Queensland, Australia. Muttaburrasaurus was very similar to Iguanodon, being a large four-legged herbivore that was capable of rearing onto two legs. Like Iguanodon it had a pronounced claw on the thumb while the three middle fingers were joined together into a hoof-like pad.

Its jaws were very powerful and equipped with shearing teeth which were probably an adaptation for eating tough vegetation such as cycads. These were common in this part of Australia at the time. Muttaburrasaurus also had an enlarged hollow upward-bulging muzzle, that might have been used to produce distinctive calls or for display purposes. However, as no fossilised nasal tissue has been found, this remains conjectural.
