These are still living amongst us, they're working with the Greys and the shadow governments, the USAF top secret, they're at war with various other Reptilian breeds, the Draco and many others, they like to eat humans, their existence is being kept secret because the human race would not accept them into society, but the thing is, they've been here for thousands of years anyway, and are living underground. There are hundreds of other species of Alien coming and leaving our planet regularly, the Raptor will surface as soon as our Atmosphere is perfect for them, this is why our air is being polluted with metal particulates every day (Chem-trailing) and the reason Fukushima was opened up for the radiation levels creating the perfect environment.
Darn I wanted to do that for so long! I even made an crosover picture of my O.C. (a raptor) fighting xenomorph. But you would do it better anyways >.< Amazing! I love it and I can never stop dreaming about aliens vs dinosaurs <3
