About Level 40 Dinosaurs
Level 40 is the max a player can level his or her dinosaur. The dinosaur either cannot be leveled, or the dinosaur can be fused with another level 40 dinosaur to make a hybrid. It takes 8 dinosaurs to make one level 31-40 dinosaur.
In lvl 40, usually the dinosaur seems to have a lot more detail and their body parts (wings, sails,feathers) seem to be more distinct and more colorful.
