This early Cretaceous dinosaur grew to around 3 metres (10 ft.) in length and weighed around 80 kg (176 lb). Its name, which means 'terrible claw', refers to the deadly claw found on each of its feet.
While small compared to other dinosaurs, Deinonychus was built for speed, and would have been an effective predator. It had long forelimbs and powerful clawed 'hands'.
In the museum, however, she is affectionately named Samantha!
