"Platanaceae dominates the late Cretaceous of North America and Hell Creek is no exception. These trees have held the same form throughout this time as they do today, as large canopy trees growing in close proximity to riverbeds. Platanites is fitting of this description."
― Saurian encylopedia
Platanites marginata belongs to the plane-tree family Platanaceae. It seems to have been a quite common tree in Hell Creek. Any kind of role in a future herbivorous gameplay, however, remains unknown.
