Gallimimus was an ornithomimid that lived during the late Cretaceous, in what is now Mongolia. With individuals as long as 26 ft (8 metres), they are among the largest ornithomimids, the only one larger being the 36ft (11 metre) Deinocheirus.
Gallimimus was ostrich-like, with a small head, toothless beak, large eyes, a long neck, short arms, long legs, and a long tail. It had a short 'hand' relative to the humerus length, when compared to other ornithomimids. The tail was used for balance. The eyes were placed on the sides of its head and the bottom front part of its beak was shaped like a shovel. Like most modern birds and other theropods, it had hollow bones. Gallimimus had numerous traits that hint that it could run fast, such as a strong ilium, heavy tail base, long limbs, a long tibia and metatarsus and short toes, but no one knows how fast it could run.
In The Land Before Time
Gallimimus appears in the book The Land Before Time: How to Draw Dinosaurs as one of the dinosaurs that the readers of the book can practice drawing.
