Hi everyone, I'm usually not on the boards but I came up with an explanation about dinobots being dinosaurs before coming to Earth if they were ever in the movieverse. What if cybertronian scientists (Including Dinobots, who are not stupid, but like to get their hands dirty) discovered Earth and came here in the cambrian era, then used genetic codes to shape the planet's inhabitants to their liking, such as forms they used and the creatures that lived on Cybertron. Tampering with the simple cells started the growth and evolution of Earth. They would come back every 1 million years to see the progress. (These scientists had no intention about telling the primes about this experiment, fearing they would harvest the star it relied upon.) After they found that most of their creations died out during "The Mass Extinction", they decided to work on different types of organisms, thus giving way to mammals and us. Then, the Primes started wondering where they were going to every 1 million years. They followed them and found this planet. They were angry at the scientists for giving life to this planet, but still followed their law about how sentient life can never be destroyed. Megatronus Prime, however, was disgusted by the "humans", as the scientists named them, and how primitive they were. He told his brothers that such a world was not worth saving, but was not successful. The rest lies in ROTF. What do you guys think? Could they make this the official tie-in/explanation to pre-earth dinos? Or are there plotholes?
