(the same guy who suggested to add the Edmontosaur)

And about the rivalry buff, their glow effect should be at the front foot (if that's what you call it). And on taming them, if you give them any kinds of berries, they'll have a 2.4% taming process (if that's what you call it i really don't know what you call it), if you give it crops you'll have a 30.5% taming process and if their favorite kibble (I would suggest it would be Extraordinary Kibble if on PC/Console and Bronto Kibble if on mobile if they would be added), their taming process would be 59.9% and their color patterns should be white and light brown, white and red, brown and orange and blue and yellow. And their egg color will be white and blue and their Kibble is used to tame the Mosasaur, to make the Edmontosaur kibble you'll need 1 Edmonto egg, 1 prime meat jerky, 2 citronals, 3 rockarrots, 2 mejoberries and 3 fiber. Edmontosaurs should be great berry collecting, hide collecting, rockarrot collecting and wood collecting.

And besides their rivalry buff, their special ability should be that they should have a pack buff and that would enhance their strength and speed. They can be found at the redwoods, near the green obelisk, and in Forests. And since I said they're the biggest Hadrosaurs I mean bigger than a giga, but sadly I don't think they should have a platform saddle. (I think most of what I said is too op but I hope this will be accepted 😊😊😊.) I hope you like the idea.
