Fastest Dinosaur in the world - Dromiceiomimus

Speed - 37 mph

It was about 3.5 meters (12 ft) long and weighed about 100 to 150 kilograms (220 to 330 lb). Its femur (thigh bone) was 468 mm (18⅜ in) long. This ornithomimid (a bird-like theropod) had very long limbs, hollow bones, and a large brain and eyes. It had a toothless, beaked mouth, and weak jaws.

The brains of ornithomimids were large for dinosaurs, but this may not necessarily be a sign of greater intelligence; some paleontologists think that the enlarged portions of the brain were dedicated to kinesthetic coordination. Compared to other ornithomimosaurs Dromiceiomimus had a short back, long slender forearms, very large eye sockets, and pelvic bones that were arranged somewhat differently.
