Probably E. regalis(which is weird because it doesn’t have the crest)

They both look the same to me

They seem pretty much the same in my eyes, though it could be due to my lack of enough color vision to properly notice a big enough difference

They are the same thing different environment influencing the colors

They are the same thing

I think they're both E. Annectens. The two Edmontosaurus Species would have probably met each other.
