Ornitomimus means "bird mimic"
Ornitomimus was 12 feet long
and when he stood on his hind legs he as 10 feet tall.
Ornithomimus looked like a featherless ostrich.
Ornithomimus had a small head, toothless beak, a long curved neck,
and thin arms which had 3 fingures with claws on each hand.
Ornithomimus also had long sprinters legs,
and a long tail that was more than half of its length.
Since Ornithomimus had a toothless beak it probably
swallowed insects, small animals, and fruit whole.
Many scientists also think that Ornithomimus
also ate the eggs of other dinosaurs.
Ornithomimus's only defense against other
meat-eating dinosaurs was its speed.
Ornithomimus lived in what is know presant day North America and Asia.
