Quick correction. Iguanodont refers to Iguanodontia, which includes species such as Dryosaurus and Parasaurolophus. What you’re probably thinking of is Iguanodontidae (Iguanodontid), which doesn’t include Ouranosaurus.We also have Ouranosaurus as an iguanodont. Yes some other families could use some more love as well. Though I'm biased myself, I love hadrosaurs and would love to see even more of them in the game.
