Gallimimus (gal-ih-MY-mus) meaning "rooster mimic", because its fossils resembled that of a very large rooster (Latin gallus = rooster + mimus = mimic), was an ornithomimosaur from the Late Cretaceous of Mongolia.

Gallimimus was rather bird-like, with a small head, large eyes, a long neck, short arms, long legs, and a long tail. The tail was used as a counter-balance. The eyes were placed on the sides of its head, meaning that it did not possess binocular vision. Like most modern birds, it had hollow bones. Gallimimus had a number of adaptations which suggest good running ability, such as long limbs, a long tibia and metatarsus, and short toes, but it is unknown how fast they could run. Binocular vision is vision in which both eyes are used synchronously to produce a single image. ...

A fossilized beak is present in one Gallimimus skull, and ridges on the beak have been interpreted as part of a duck-like filter-feeding mechanism. However, similar ridges are seen in herbivorous sea turtles, and ornithomimids were relatively common in seasonally dry environments where filter-feeding was probably not a viable lifestyle. It seems more probableGallimimus was probably an omnivore or herbivore, using its beak to crop plants.
