In Jurassic Park, a book written by Michael Crichton and later adapted into a movie, John Hammond took dinosaur blood out of petrified mosquitoes in amber. He then patched the gaps of the DNA with Frog DNA, and created... a dinosaur. Now, that's not possible because of obvious reasons (Dinosaur + Frog ≠ Dinosaur. Dinosaur + Frog = Weird mutated thing. Also, ancient DNA have never been found to have more than 250 complete base pairs, while an entire dinosaur needs a few billion)
They did it in Pokémon too. Y'know, when you take the Old Amber to the Cinnabar Lab and get Aerodactyl?
What do you think they used to patch the Aerodactyl DNA? Poliwhirl DNA, maybe?
