Gallimimus was an omnivore that lived in the Late Cretaceous, about 75-70 million years ago. Gallimimus means "rooster imitator" and was very similar to today's ostriches. These long-necked, long-legged creatures inhabited Asia and North America. 

It had great vision, thanks to its large eyes. They are the fastest of all dinosaurs, its long tail helped it to keep its balance when running and stabilized it in fast turns. It had a small head with a long beak. 

Gallimimus' arms, claws and hands were short, it also had elongated forelimbs. And because of this, it was discovered that they were likely to cling to tasty tree branches while feeding.

At first, scientists thought they were herbivores, but later discovered that these dinosaurs ate small Cretaceous animals, insects, eggs and plants.

It was about 4-6 m long, 1.9 m high at the hips and weighed 440 kg. Like most modern birds it had a hollow bone. It could run at speeds of about 43 miles per hour.
