GALLIMIMUS
Pronunciation: gal-uh-MY-mus  
Translation: Chicken Mimic
Also known as:

Weight: 260 pounds (118 kg)
Period: Late Cretaceous


Notes: Found in southern Mongolia, Gallimimus is the largest ornithomimid to be discovered, and the only one for which a good skull has been recovered. The skull reveals that Gallimimus' snout was like that of a modern-day goose -- flattened at the end. Its neck was long and mobile, suggesting the ostrich, which it resembles. Its hands were thin and probably too weak for strong grasping.
