A little strange making an idea thread just to suggest five new dinosaurs...
That said, I agree with your suggestions, except for maybe Tenontosaurus... I do think it should be added eventually, but I feel something like Dryosaurus should be a higher priority, as we have yet to get a hypsilophodont-type dinosaur... meanwhile your list already contains Iguanodon, and Muttaburrasaurus is already in the game, which for now sufficiently covers iguanodonts.
