ANATOMY
Gallimimus was a fast-running dinosaur with a very long, thin, flattened, toothless, horny beak, a small head, and a relatively large brain. The bottom front part of its beak was shaped like a shovel. It had large eyes positioned on opposite sites of its head, ruling out binocular vision (depth perception). It had a long neck, long tail, long legs, and hollow bones. Gallimimus was up about 17 feet long (5 m) and may have weighed about 60 pounds (27 kg).
This oviraptorosaur had short arms with three clawed fingers on each hand, and long legs with three clawed toes on each. A long tail acted as a counterbalance and as a stabilizer during fast turns. Its bones were hollow.
WHEN GALLIMIMUS LIVED
Gallimimus lived in the late Cretaceous period, about 75-70 million years ago.

BEHAVIOR
There is no evidence that Gallimimus gathered in herds.

INTELLIGENCE
Gallimimus was a theropod, whose intelligence (as measured by its relative brain to body weight, or EQ) was high among the dinosaurs.

DIET
Gallimimus may have been an omnivore, eating small animals, insects, eggs, and some plant material.

LOCOMOTION
Gallimimus walked on two long, slender legs. It was a fast, agile dinosaur, probably running about as quickly as an ostrich , which can run up to 43 mph (70 kph).

DISCOVERY OF FOSSILS
Gallimimus was found in the Gobi desert in the early 1970's. It was named by paleontologists Rinchen Barsbold, Halszka Osmólska, and Ewa Roniewicz in 1972. Several fossils have been found in Mongolia.

CLASSIFICATION
Gallimimus belonged to the:

Kingdom Animalia (animals)
Phylum Chordata (having a hollow nerve chord ending in a brain)
Class Archosauria diapsids with socket-set teeth, etc.)
Order Saurischia - lizard-hipped dinosaurs
Suborder Theropoda - bipedal carnivores
Infraorder Coelurosauria - lightly-built fast-running predators with hollow bones and large brains
Superfamily Maniraptoriformes - advanced coelurosaurs with a fused wrist bone
Family Ornithomimosauria - ostrich mimics, the fastest dinosaurs. Had large eyes.
Genus Gallimimus

species bullatus (the type species, Osmólska, Roniewicz, and Barsbold,1972)
species mongoliensis (Barsbold, 1996)
