The one and ONLY thing standing in the way is the fact that a Parasaurolophus is in the film. Like, if you changed the crest...and NOTHING else... the scene would still work exactly right.

So what I think this seems to show is that the intent was Corythosaur up to a point: the real question is WHEN was that point?

It seems to have been AFTER filming completed but obviously before completion, so I narrowed it to the stage of post-production when the film was turned over to ILM ("ILM stage"). Thanks for clarifying. It appears it was pretty early in development as there exists concept art of a red-crested Parasaurolophus (that can be seen at 3:24 of this video) which Paul Mejias made a maquette of and there's a photoshop rendering by Stefan Dechant of a red-crested Parasaur being restrained by the hunters like Elvis in the final film (this piece of art is included in the book The Lost World: Jurassic Park.
