New Food Types; Cycads and Fern Trees
currently creatures like Iguanodon, Stegosaurus and Lambeo have very limited diets currently while also having to compete for the exact same food source. It would be far more interesting to add some more medium or high foliage for the more high browsing creatures to be able to eat.
Tree ferns and cycads would be perfect due to their easily identifiable appearance and prehistoric feel while also not clashing with the environment.
These would also be great sources of food for Barsboldia and Amargasaurus is the future.
I'd like to add it could also use a recolored version of the pine cone on a normal ferns to make it appear like a cycad fruit.
