>>53841924>Pokemon goes extinct>gets revived as a fossil>fossil Pokemon get out into the wild>this new version of the pokemon now exists as time passes in the Pokemon UniverseIt's a little inconsistent, both Mega Aerodactyl and Tyratrum imply that the Pokemon revived via fossil aren't the "true" form of the Pokemon, but then I think it was Kabuto who was stated to have actually been hidden away all this time, so it's your usual "Pokedex is weird" business.
