Hold on to your butts, you’re about to get schooled … in dinosaur kills.

The nerds at Dog and Pony Show break down all the prehistoric carnage from the three ‘Jurassic Park’ movies in this handy graphic, which ranks the dinosaurs based on the number of people they killed in the movies. And guess what? The Velociraptors have the most blood on their hands. Surprise! We think it’s because they figured out how to open kitchen doors; that stupid T-Rex could never learn how to do that, especially with those tiny Cee-Lo arms.

What’s your favorite ‘Jurassic Park’ kill scene? We love the one where a bloodthirsty Giganotosaurus mauls ‘Jurassic Park 3’ director Joe Johnston in his trailer. (OK, maybe we just imagined that one after seeing that terrible movie.)
