Gallimimus

Gallimimus is a genus of theropod dinosaur that lived in what is now Mongolia during the Late Cretaceous period, about seventy million years ago. Adults were about 6 metres long, 1. 9 metres tall at the hip and weighed about 440 kilograms. The fossil remains were discovered by Polish-Mongolian expeditions in the Gobi Desert of Mongolia in the 1960s.
