Ben Bird Dragon is the fastest dinosaur known at present, with a speed of over 70km/h and agility, which is equivalent to the running speed of horse racing. It looks like a giant bird without feathers. It was the champion of theropod long-distance running in Cretaceous.

Brief introduction of bird running dragon

In the world of dinosaurs, in order to survive, everyone played their own advantages, among which, some were good at running. Benniaolong was the champion of long-distance running of theropod in Cretaceous. Beaked mouth has no teeth, long neck T-bone and thin and long hind legs, which is good for running. The tail is very hard. When running, the tail stretches straight back, which can be used to master the direction of running.

The bird-running dragon found in Canada is about 3.5 meters long. Among carnivorous dinosaurs, it is considered a small dinosaur. But its running speed is extremely fast. Scientists calculated the running speed of the bird dragon according to its fossil footprint, which is about 65 kilometers per hour. No dinosaur could compare with it at that time.

The ability to run fast gives this dinosaur an advantage over other animals: first, chasing prey; One is to avoid the enemy's attack. As a result, the fast-moving herbivorous dinosaurs and carnivorous dinosaurs began a speed race: in order to escape from the faster and faster carnivorous dinosaurs, herbivorous dinosaurs must also be able to run faster and faster.
