Fact File

Length: 4 metres

Height: 2.5 metres

Weight: 500kg

Diet: Omnivore


Though classed as a theropod, a meat-eating dinosaur, Ornithomimus was probably an omnivore. It would have eaten plants, eggs, insects and meat, depending on what was available. To avoid becoming a meal for dinosaurs like T-Rex, it could run very fast, and would have lived in groups so they could stay alert.
