Ornithomimus facts for kids

Scientists think they probably looked like a feathery kangaroo - but they could run as fast as an ostrich. It used this as a defense - it would run to safety if a predator arrived.

It had 3 toes on its hind legs that would dig into the ground when it was running - like spikes on running shoes.

It is thought they could run at speeds of up to 40 mph, which means it would take them only 5.59 seconds to run 100 meters - almost twice as fast as Usain Bolt's 9.58 seconds!
