the Autobots and the Decepticons crash-landed on Earth centuries ago, and they where all in stasis lock. But millions of years ago. The Dinobots where awaken in the cretaceous paired. And took the form of there iconic dinosaur forms. Snarl not particularly liking his. But some kind words from Swoop make him change his mind about it a little. And it's a day before the asteroid hit earth. But Telatran 1 alerted them when the asteroid came into earth's orbit. Luckily for the Dinobots, they got back into there stasis pods at the last second. Saddened by the thought of not being able to save at least some of the dinosaurs. But then the autobots and the decepticons awakened in the present day, near Central City. But the Transformers remain hidden from the humans, at least for now, thus reinforcing the "robots in disguise" concept.
