Hello There! :)

Because there is not a single dinosaur that has ever appeared in Jurassic Park.

Not one. Not in the books. Not in the movies. Not ever.

"Now what John Hammond and InGen did at Jurassic Park was to create genetically engineered theme park monsters." ~Alan Grant

Grant says that in a moment of cynicism. It's part of his arc for the film. But it's not inaccurate. What Jurassic Park has, what it's always had since the very first novel, are "Mostly Dinosaurs".

"And since the DNA is so old, it's full of holes! Now, that's where our geneticists take over!" ~Mr. DNA

It's impossible to recover a fully intact gene sequence from an ancient amber mosquito. Cloning a pure dinosaur would have been completely impossible, and so the park filled in the gene sequence with whatever works. Frog. Lizard. Bird. Whatever they need to get the result they are trying to get.

Every single dinosaur is a chimeric beast made up of mostly dinosaur and a bunch of other stuff that some scientists thought would achieve the appropriate dinosaur-like result.

"Nothing in Jurassic World is natural! We have always filled gaps in the genome with the DNA of other animals. And if the genetic code was pure, many of them would look quite different." ~Dr. Henry Wu

Which, from a writing perspective, is fucking genius. Because now you have a preset excuse for each and every plot hole your movie has.

Like. Why don't the raptors have feathers? Because of the chimera DNA.

Why do dilophosaurs spit venom? Because of the chimera DNA.

Why do T-Rexes have movement based vision? Oh, they don't. But Rexy does. Because of her chimera DNA.

Why is the Spinosaurus so fucking big? Because of the chimera DNA.

Why are the velociraptors mislabeled? Because Hammond's a dipshit.

feverly making this shit just because i saw this
