Why exactly? Ouranosaurus is an iguanodont just like Mantellisaurus. With Muttaburrasaurus you would not have the thumbs, the headshape had to be changed and the bodyshape is different. The bipedal Mantellisaurus is just a suggestion by Gregory S. Paul because of the shorter front legs. It is said Mantellisaurus was quadrupedal and bipedal, but favoured being on four legs. Like JWE's Ouranosaurus.
