As someone who routinely works with this material, I am not planning on using the name Mantellisaurus. The differences between the species have existed for some time (indeed, over 130Million years), and were recognised by Norman in his many papers on the animals, and he never saw fit to split them. In real terms, one name or the other merely serves to create more monospecific genera, which in my opinion is not a desirable thing.

Maybe keeping both in *Iguanodon* would make *I.* paraphyletic? In that case separate genus names -- actually clade names -- make sense.
